A story from a cloaky camper and an attempt to build a beast mode multi-boxing server.

21/04/2018
Hello Nerds!
 
Some of you may know me, some may not. Those that do will know I offer cloaky camping services over new eden. I do camping contracts / extort renters and focus my time hunting botters when the contracts are quiet. I offer PvP entities access to my cyno network to get dank kills and big escalations. From super carriers to Rattlesnakes.
 
The thing that got me into camping was hunting bots back in the dronelands a few years ago. I realised the most effective way to hurt them was to camp them 23/7, follow them around using locator agents. Eventually they had to rat with me in system. When they did I setup bubble traps etc and dropped blops and cleaned them up.
 
The 2nd thing I love about cloaky camping is the ability to counter Alliances (i feel its overpowered) intel channels / networks. Think about it. They have multiple intel toons dotted around the entrances to their pipes reporting hunters coming into the pipe allowing the PvE players to warp off and safe up. They even use external programs to collect this intel and give audible alerts. Cloaky camping is just the polar opposite. Dotting toons in their ratting pocket and giving me intel on whats going on in their system. As long as local chat exists so will cloaky camping. I'm pretty confident CCP share the same thought.
 
People probably think cloaky camping is easy. You are wrong. The prep work and behind the scenes work that goes into it is pretty immense. You are about to find out.
 
The hardware i'm currently running the 60 clients on is as follows:

Camper2:
 
How do you pay for 60 toons
I started with 10 campers and made ISK by other means. When I made new campers I invested ISK and started to Skill extract and plexing the toons. I also make a decent amount from people who pay me to camp others.
 
The Setup  
I manage the clients window positions and CPU allocation with ISBOXER. Its legal to use as long as you don't use input broadcasting. I boot up the clients with ISBOXER EVE Launcher. I copy the window positions / chat channels etc over using garpaui. I use remote desktop to manage the clients light cynos etc.
Example here
 
On both motherboards I had to under clock the processors as they were drawing too much power from the motherboard and causing the chipset to overheat. I think these motherboards are not beefy enough to support these 8 core processors. It caused the CPU to throttle reducing the clock speeds to 1.3Ghz and causing lag issues. I solved this problem by reducing the clock speed from 4Ghz to 3.6Ghz and reducing the CPU voltage. This reduced the heat by a really good amount and stopped the problems.
 
However, Me being me I wanted to expand and the camping pcs were running at full chat. So I needed a better piece of hardware to host these 60+ clients. So, while at Fanfest, I bidded on this R820 Server on ebay and won!
 
Specs:
 
The hardware should be able to support multiple clients. However i'm not too sure how eve is going to behave when I try and open 60 instances all in one OS. I have set myself up for a hell of a challenge! However, I feel like I got a pretty good deal on the server and DELL hold their value. I'm sure I can re sell it if the project fails.
 
Things to work out:
 
Things I will teach you guys
 
I'm learning too so your help input would be awesome! First question. Shall I just update this reddit post each time or create some sort of blog?
Old AMD FX Rigs
New Kit / with various bits I gathered to get started
 
Update 23/04/18
I have made some decent progress on this crazy project. I will give some breif updates here. I will get a blog up and running to post full details with how to's etc. Its probably way to long for reddit.
 
I have successfully installed some GPU's into the R810 AMD R9 280x and Nvidia GTX 970. I soldered some PCI-E cables to the PDB and it worked fine. The GTX sits nicely in the chassis however, the R9 280X is external atm using a PCIE x1 to x16 riser (from my bitcoin mining). Also I have managed to enable and use them both with passthrough in ESXI 6.5. Yes the GPU works with a x1 adaptor. WTF!
 
Freezing Problem with a single os install
If I try and run more than 40 clients in a single OS I the system freezes when loading up client 41. I have tried the following:
I cannot see why it is freezing. Is there any way to gather logs for the client? It doesn't appear to be a resource problem. Plenty of RAM / CPU and HDD isn't going crazy.
 
Here are some pics of the current progress:

[USA-IN][H] Sapphire R9 280x, GTX 660 2gb, iPhone 5s [W] Paypal

Edit: Repost
Edit: 280x sold to LactosBear
Edit: GTX 660 sold to Vexedly_
Edit: GTX 660 is available
Hey everyone! Just trying to sell off some of my old hardware I had laying around.
I have a Sapphire R9 280x Vabor-X. This model is pretty much the Bee's knees of the 280x's. Full disclosure! I mined on this card for about a month way back in the days of Bitcoin and Litecoin mining. However, the card still runs super cool and stable. Has fresh paste on the card and runs at 45-50C when gaming! This card still rocks at 1080p gaming and does't mine crypto currency all that well which keeps the price down :D I'm asking $130 shipped.
I also have a EVGA GTX 660 2gb. Has fresh paste on it and runs super cool. A great budget card for 1080p gaming. I'm asking $55 shipped.
Finally I have an iPhone 5s up for sale. It's a 16gb AT&T model. It is slightly bent(as pictured) but still works great! According to my girlfriend it is unlocked. She just happened to have an AT&T contract with the phone. I'm asking $90 shipped OBO.

Crypto Gui Miner - official thread and support

This is the official thread for support and development of CryptoGuiMiner! Please any suggest, criticize and praise.
I see that there are a lot of questions and different answers on forums on the subject of mining cryptocurrencies. So now… which cryptocurrency should you be mining and how? For beginners and people with no knowledge of cryptocurrencies, the biggest issue are the very basics like adjusting the settings which can be complicated and hard to figure out. If you want to start mining, it must be way more complicated than just a few clicks! Or is it? So you don’t have to bother, lose time or God forbid adjust something wrongly, there is an interesting piece of software that helps you and does everything automatically for you. I’m writing this because I myself am using this software and can confirm that it is definitely the best solution for everyone who is new in the world of cryptocurrency mining.
The program is called Crypto Gui Miner and it you can download it from https://cryptoguiminer.com/ (Crypto Gui Miner | Free Easy GPU Mining Software Application)
The main thing which makes this program so special and what sets it apart from the others is the simplicity and automatic set-up function. There is even a calculator on their website that will calculate which cryptocurrency is the most profitable to mine, depending on the graphics cards that you use.
When you run the program, it will automatically recognize the graphics cards that you are using and adjust the settings so that it mines the cryptocurrency that is the most profitable. You also have a nice and clear display of temperature and other useful data such as hashrates, estimated monthly earnings in US dollars or Bitcoin, monitoring for tracking results via mobile phone, etc. All you have to do is insert your wallet address so you can dafely save the currency you are mining directly into your wallet (and it is saved automatically). The best place for creating your wallet is the official website of the cryptocurrency that you wish to start mining. Of course, you always have control over what and when you will be mining.
You can also enter more than one wallet into the program, so the program will mine the currency that is the most profitable at that time. However, if you only wish to mine one cryptocurrency, then just click on the button “Force” and the chosen cryptocurrency will be mined regardless of the others.
In short, don’t focus on mining Bitcoin, Litecoin, Ethereum or other currencies that are difficult to mine and you need hardware of 100+ thousands of EUR. Focus on currencies that can quickly be mined and monetized, converted into cash or for buying other cryptocurrrencies or if you plan to invest them in the long run. Just download the program, choose one or more currencies for mining, insert your wallet and that is it. No complicated settings, losing time, uncertainties etc.

Advice? Going a bit insane.

I have a simple set-up I've been trying to get running stable for about a week now. I have 2x nVIDIA GTX 980 and 2x Radeon 29 280X cards that I want to use.
I have previously used just the GTX 980s and they were stable for weeks. I recently acquired the 280s, and while I can't be certain, I think the cards are not at issue.
I also had two of the 980s and one 280 running in my desktop stable for quite some time, just as a tester. But for the actual mining rig, I was using old AMD AM3-based hardware. And I've had nothing but problems. Murphy's law.
First, I had a motherboard go out (ASUS M4A87TD EVO.) Luckily I had a spare. But the ASUS board had two native PCI-E x16 slots (one running at x1 speed,) and so I had been running the 980s both in the motherboard, and was using this riser extender to run the other cards, with molex->SATA risers (I don't have enough native 4-pin connectors to run without molex to SATA adapters.)
The "new" board (which is actually chronologically older and older tech) is a Gigabyte GA-MA785GM-US2H. It's also socket AM3 but only supports DDR2 memory; luckily I had old DDR2 available. This board also only has one x16 slot, so I am running 3 GPUs outside of the chassis with x16 risers.
It turns out after some nightmare of troubleshooting that one of the DDR2 DIMMs is probably bad. I don't have a replacement at the moment, but I've tried running everything with one DIMM.
I also have Virtual Memory (swap/page file) set to 16GB. I don't know why this is necessary, but other people mention it and NiceHash wouldn't let me run 4 cards without it.
Anyway, all works "fine;" I have the 280s set to 850MHz core clock and +20 power with 100% fans, and 100% fans and native clock on the 980s.
But I keep getting crashes. Before I had freezes, so I also changed out power supplies several times and tried everything you can think of. I don't think the issue is down to power any more, but I'm open to correction if anyone has a suggestion or tip.
For power, I'm using a 3 to 1 ATX-24 pin adapter, with a SeaSonic 620W as the master, and a Corsair 550W as the "slave." The SeaSonic powers the motherboard and the ATX12V for the CPU. It also powers the 3 SATA to molex adapters for the x16 risers, and the 8+6 pin PCI-E power connectors for the 280s.
The Corsair powers the HDD (this I have also suspected of causing problems but I have swapped HDDs and had the same issues, and I really need to get an SSD for this thing,) two 120mm intake fans, two 140mm exhaust fans, and the 6 pin PCI-E connectors for the 980s.
It doesn't seem to freeze anymore. It will mine just fine for a while but eventually I will get a BSOD, usually saying that the device driver has gone into an infinite loop. I believe this is the Crimson driver (I am using version 15.12.)
I've swapped CPUs and memory and HDDs and motherboards and I'm just almost at my wits' end about to tear my hair out trying to get this thing to run stably. I most likely just need to get all new mainboard/CPU/memory, but I can't do that at the moment, so I am looking for any advice/help I can get.
I would assume the driver is going into an infinite loop because it's polling hardware and not getting the response it expects or something like that, which could indicate a power or heat issue, but I don't know. And I've searched for the BSOD error and 90% of the results for "device driver went into an infinite loop" (paraphrasing) were related to AMD Crimson drivers. So that's been where my suspicion has been so far, and I've had other problems with getting the AMD stuff to work when I was initially setting it up. (And had problems with AMD/ATi drivers going back 20 years, ugh.)
So.. Any advice?
TL;DR: Running 2x GTX 980 and 2x R9 280X; keep getting BSOD about device driver going into an infinite loop after some time mining. Want to stab myself.

Is Dogecoin mining profitable? No.

I love Dogecoin, and I love the dogecoin community. So I thought I'd take a moment to look at whether it's worth buying mining hardware to get Dogecoin, or just buying Dogecoin itself.
I had another redditor give me some figures to go off of, so I ran the numbers on Coinwarz and this is what I got:
A 280x costs $440 right now on Amazon.
I'm going to assume for the purposes of this calculation that no other hardware would be required other than the card. If someone else can give me an estimate for the accessories, please do.
We're getting 700 KH/s with power consumption of 260W, and electricity prices of $0.10 per KW/hour (the US average right now).
I'm using the coinwarz calculator to determine revenue (I set the equipment cost to $0): http://www.coinwarz.com/calculators/dogecoin-mining-calculato
Where people get tripped up is that they don't account for the difficulty increase. So what I've done is look at the Dogecoin and Bitcoin difficulty increase over the past month, and done a week by week look at the returns, assuming the same weekly difficulty increase as each currency had.
Dogecoin's difficulty went from 472 to 1385. That's a 193% increase in a month. Bitcoin's difficulty went from 1180-2193, an 85% increase.
Assuming a 193% increase, the difficulty will rise to 4058 by the end of the month.
To calculate the difficulty for a week, we use the average difficulty between the beginning and end of the week. The difficulty goes up 664 a week, so we take half of that and that's where we start the first week: (since the week starts at 1385 and ends at 2049, we add a half week's increase to get the average of 1717.
Week one - 1717 Difficulty: $55 Week two - 2381 Difficulty: $39 Week three - 3045 Difficulty: $29
Now i'm being generous because the reward halves in 18 days, but i'm pretending it lasts 3 weeks.
Week four - 3709 Difficulty: $10
Added together, you make $133 your first month. At the end of month difficulty (4058) You'd make $8.27 per week, or 38 weeks (or 9.5 months) to break even. And that's assuming the difficulty stays the same after one month.
Now, running the numbers assuming the 85% increase that bitcoin experienced:
week 1 - 1532: $62.60 Week 2 - 1826: $51.82 Week 3 - 2120: $44.02 the mining reward drops by 50%: Week 4 - 2561: $16.88 = $175.32
Assuming the same difficulty as the end of week four (2562) in perpetuity, it would take you 17 Weeks (4.3 months) to make back your initial investment. And that's assuming the difficulty stays the same, which it won't.
And if you're going to assert that "well, that's based on the fact that the price will stay the same, but part of the reason you mine is cause the price might go up!"
Yes, the price might go up, but you'd make the same amount of money buying $450 Dogecoins. The question is not "are Dogecoins a good investment?" It's "is mining Dogecoins a better investment than just buying them?"
TLDR; buying new hardware to mine Dogecoins is a bad investment when you take into account the rise in Difficulty.

How secure is the Vertcoin network from new-entrant bad actors? Let's do the math.

The core foundation of a cryptocurrency is the network's security yet we don't have a common methodology to compare currencies.
Thus I propose one method: the capital to market cap ratio.
To start let us calculate Bitcoin's C2MC ratio. Since BTC is an asic coin we need to estimate the cost to design and manufacturer enough asics to 51% the network.
The best method here is to look at the best value non-scam asic. The logic being if a for-profit company can bootstrap production at their public asking price then so could a malicious attacker. It does not matter for our calculation that the asic producers are abusing their customer's preorders and mining for their personal benefit, all that matters is they could produce the hardware. After all an attacker would also mine before they attack.
For our calculation let us use the KNC Neptune which costs $5,995.00 and hashes at 3TH/s. Then take the Bitcoin nethash: 83,161,066.76
Combined we get the formula: ((83,161,066.76 / 3000) * 6000 ) / 7,395,527,268
We thus find Bitcoin has a whole 3 cents of hardware defending every US dollar of BTC.
Now lets do it again for Vertcoin. To make things harder for Vertcoin we will only count the cost of the GPUs. We are thus ignoring the motherboard, power supply, and even CPU. We'll use the 280x which can be had right now for $300 and hashes 350KH/s.
We get: ((7629439.6 / 350) * 300) / 4900000
Or: 130 cents per US dollar.
So there, four months on we can say with confidence that asci-resistance leads to a stronger network. In other news, we've just redesigned the vertmarket so you should try selling something with your super-secure vertcoins.

Scrypt-N, what is it?

OK, so I started mining Bitcoin with 336Mh/s USB ASICs back when they were $10/each. By the time January hit they were useless, although they still generate about $7/week.
Then I bought an overpriced R9 280x and have been making a decent return every week. Now I'm seeing hashing speeds drop and on /litecoinmining I see posts about how there are scrypt ASICs coming.
I was really disappointed to hear this as I thought (and have argued this with friends) that Scrypt coining has been generally safer because to get high hash rates we all have to buy the same type of hardware, video cards, which usually only do 1 or 2 generation bumps a year, and those bumps don't always come with huge performance increase.
I also saw a few comments about Scrypt-N coins (panda, quark, etc.) How do these hashing algorithms differ from Scrypt coins (litecoin, feathercoin, doge, etc.)? Are they truly safe from ASICs? Should I switch to mining Scrypt-N coins now, and if so, which coins would be recommended?
I don't want to switch to a coin that's just going to be a pump and dump as I don't believe they truly help the community.

Used Hardware and warranty

About the time video cards were becoming not competitive doing Bitcoin mining, Ebay filled up with cheap second hand cards as the miners unloaded their rigs to recover some of their investment and contemplate their ASIC future. These cards had been running flatout for months and were considered pretty sketchy hardware, so they went cheap. I went looking for a bargain, and bought a 280X for $150.
Thing was, I bought an MSI, knowing that MSI supports warranty from the day of manufacture, and doesn't care who the owner was/is. Months later, running PVP WOW sessions at max quality it started bluescreening. I could run it fine if I dialed the quality back a step and frankly I couldn't tell the difference but it wasn't supposed to do that. No doubt it's prior life getting flogged as a Bitcoin slave hardened up some thermal interfaces. After verifying several times that I could induce a bluescreen at will just pushing up the settings and jumping into a 40 man PVP fight - off it went to the warranty doctor.
Today I got a new one in the mail. :o) MSI is a great company.

[Question] My friend has about 9 spare R9 280X's

Hi,
So my friend has 9 R9 280X's that he got for bitcoin mining. They are useless now as there is specialised hardware for it. He sells them for €200 while buying new ones cost €250.
He has no boxes of them anymore, but he does still have the manuals and cables that came with them.
Is it worth it? Should I just buy them new instead?

SHA256 with ASIC compared to Scrypt with GPU

this is the very basic for latecomer always doesn't understand.
i keep seeing they insist on mining bitcoin with SHA256 ASIC, i know its fun, its fun to see you generate money out of thin air, but thats not how we do it today because SHA256 ASIC era are gone, its very expensive playing field right now, if you insist want to mine some bitcoin, you should start mining using GPU! why?
lets calculate profitability of your SHA256 ASIC, and lets make it really easy by assuming some factor :
now go here you will see you will get 1 BTC in about 75 days right now (see the 2nd column from the rightmost), this value is not correct since it does not account for difficulty increase within 75 days, bitcoin difficulty are increasing about 35% in 2 weeks, thats about 70% per month, you will see the correct calculation is here which you will never get 1BTC within a year, and after 6 months your ASIC doesn't generate bitcoin anymore
now lets compare it to GPU miner for Scrypt mining, which i use realistic assumption here
now go here, you will see that on the most profitable coin (first row) you will get 1 bitcoin for about 30 days (its 45 days faster than SHA256 ASIC), how about difficulty increase within these period, this factor is not as scary as bitcoin, lets see difficulty chart for LTC here, you will see that the diff is up and down, by calculating the data history for 1 year, you will get that LTC difficulty increase is about 3% per month on average (this is 25x smaller than bitcoin difficulty change rate), so coinwarz data is not too much way off here by not take into account of difficulty increase
TL;DR;
note: this calculation are made in worst case scenario for GPU compared to best case scenario for bitcoin ASIC
thats just prediction and calculation, things will go wrong right? lets see the report from my own GPU mining rigs here, see 2nd sheet (RIG1-Report), this is my earning report day to day in BTC (already running since december 2013), my rigs cost about 2000$ (this is 2nd hand 6x AMD 7970 for 4.2MH/s) and will ROI within 50 days from start if my calculation are correct

GPUs will make a comeback to mining, and in doing so, will destroy the security of the Bitcoin network

The reason why Bitcoin is relatively secure right now is because the cost to mine is extraordinarily expensive.
Why is it so expensive? Not because of the cost of the silicon, or even really the cost to manufacture, but because the only use of an ASIC is for mining SHA-256 cryptocurrencies such as Bitcoin. When people pay up to $15,000 for an ASIC miner, they're paying for all the time and effort that went into it.
But consider this: What if mining machines become multi-purpose? In particular, what if GPUs return to the fore as competitive mining machines?
Now I know what you're thinking; you're thinking 'You fool, GPUs will never come close to the efficiency of an ASIC'. But the thing is, they don't need to be. They only need to be cheap, since the purchase cost of an ASIC greatly outweighs its electricity cost.
A 'CoinTerra AIRE' ASIC slated for release in March this year will cost $2499 and do 4500 GH/s. Now taking into account a number of factors like electricity cost and rate of value depreciation, I'd estimate that for a $200 GPU to be competative, it needs to do about 225GH/s - an improvement of 375x on current hardware. Impossible you say? Well, the hash rate of nVidia GPUs has improved by ~70-80x in just a few years, without any intentional focus towards Bitcoin: 5.66 MH/s 8600GT to ~414 MH/s GTX 960.
The nVidia GTX 780ti is a top of the line card currently priced at $440 and it does 0.5 GH/s, yet an Ati 280X which costs just half the price does at least 0.7 GH/s.
Ati cards have always displayed better performance in mining, but why? I'm no expert on the technical details, so I'll only say what can be deduced and is relevant: GPU designs can be altered to increase efficiency/performance when it comes to Bitcoin mining - this is a proven fact from the Ati/nVidia difference!
So far, these chipset makers have no doubt been focused on improving gaming performance. But what if they realize that there are many people who will buy more of their GPUs if they have the added benefit of good mining performance, as in 2011? Surely it wouldn't be too difficult or expensive to rearrange things a bit or slap a few things on - If a bunch of amateurs can create ASICs, how difficult could it be for a multi-billion dollar company to improve the hash rate of their GPUs at minimal extra end cost to the consumer? Or what if gaming just naturally tends more towards GPUs having better hash rates?
When this happens, Bitcoin will have a security crisis on its hands. There are millions of people with mid or high level graphics cards. In Q1 2014, AMD and NVidia sold a combined 14 million add-in boards. But let's be conservative - let's use the publically available Steam data, which says that yesterday there were a peak 8.3 million concurrent users online. Steam's hardware survey says about 65% of these are not mid or high level cards, so 0.35 x 8.3 mil = 2,905,000 people with decent AMD or nVidia cards who are conscious users (i.e. not office workers) at a certain time of day. For those 2.905 million gamers to launch a concerted and sucessful 51% attack on the network, their GPUs would only need to do on average 57.14 GH/s. If $200 GPUs were to be doing 225 GH/s, the entire number of ASICs throughout the world would be no match!
If you want a 'tl;dr' then go listen to Fenton or Shrem egg you on to buy or something - stay in your little dreamland while the price falls like a rock

Earning Beer Money with your Idle Computer(s)

Just wanted to share my experience with you all since many of you have access to powerful GPU(s) and cheap/free electricity (office building).
I recently started looking into mining cryptocurrency with my video card. I chose Monero. It seems to be getting popular as seen on https://www.coingecko.com and https://coinmarketcap.com.
Bitcoin is no longer viable to mine using GPU and needs specialized hardware (ASIC).
To see if it's worth it to you. You can follow these steps...
  1. Get a Monero wallet like https://mymonero.com
  2. Download and install mining software from a pool close to you like the ones listed here... https://monerohash.com/#network . When you choose a pool and go to their site, there should be a "Getting Started" section like this one.. https://monerohash.com/#getting_started .
  3. Run the software, and get your hashrate
  4. Plug your hashrate into a profit calculator like this one.. https://www.cryptocompare.com/mining/calculatoxmr
  5. If the numbers seem good to you, just run the mining software whenever you are not using your computer(s)
For me, I'm using an AMD 280x GPU which is not the fastest video card around. My hashrate is about 542 H/s. I got paid out 1.2 Monero in 1 week which is about $10 USD. It's not a whole lot, but just enough for /beermoney.
You'll earn more than me if you have a more powerful card and/or mine on multiple computers.
After you earn some Monero, here's some things you can do with it..
If you have any questions about Monero, there's a great little community over at /monero

Such Community

Hello fellow shibes, I just wanted to let you guys know the (short) story of my conversion to this coin and community.
I started mining litecoin 6 days ago with my two 560's after finally taking a good look at bitcoin, and then other major coins.
"Nah, i wont even look at doge. It is a silly place" - zMaile
5 days ago I started hashing, and figured out the hardware, terminology, configurations, and pools. Found multipool which as you all know mines the 'most profitable' coins. DOGE was sitting around 75% time spent hashing if i remember correctly.
"I need more GPU!" - zMaile
4 days ago I got an R9 280X. I also noticed that I was getting disappointed when i was mining anything other than DOGE.
"But DOGE just isn't as profitable. It isn't worth mining 100% time" - zMaile
Today I looked at this subreddit. I've read pages. I've subscribed, and I've moved everything from my BTC and LTC and everything else to DOGE. I have seen the moon, and I would very much like to go there. I now mine 100% DOGE.
Tomorrow I shall look at other DOGE pools, and shall begin tipping like a bus with undersized swaybars!
"I see no reason for the first public moon-flight to not be paid for with DOGE" - zMaile

[CANADA-BC] [H] Crypto Currency Mining Enclosure and hardware FULL setup sale [W] $ or Bitcoin

I own a crypto currency mining investment company and I'm selling off the current hardware setup. It has been in use since mid-March of 2014. I've had a series of unfortunate events occur in my personal life that require me to sell off my business's hardware and other personal items.
This is for a firm priced sale, I am looking for a buyer that is either wanting to get into the mining business and wants a GPU based setup that can tackle all the new algorithms VS ASIC based setups that go obsolete within months and have no resale value. Or a buyer that wants to expand their mining farm or mining business and would love a plug-n-play type setup where the only thing they are required to do is have one power feed wired into their warehouse or home panel. This would be for local pickup only most likely. It will require the buyer to have a truck or to rent a u-haul type of moving truck. The system is roughly 60 inches tall by 95 inches long by 24 inches wide, not sure on its weight but moveable if the cards are removed(the cards are designed to be plug-n-play as well, no screws, just pop out pop in.) and runs at 240v for PC hardware and 120v for fans/misc regular appliance plugins(routers/switches etc).
The enclosure houses 8 systems which consist of 46 R9 280x video cards (it has room for expansion), has its own built in surge protection system to withstand lightning and other outside-the-enclosure based surges, whole system runs at 240v for best efficiency, has a 100amp breaker panel which is attached to the enclosure for maximum expansion.
The enclosure has 6x20 inch box fans which provide the 24/7 constant air flow for the video cards. I have two other 20 inch box fans that are for in and out airflow for fresh air circulation. All video cards are easy to access and can easily add or remove cards to/from the unit. I built the enclosure design in-house.
Serious inquiries ONLY, I have priced this as fair market price for used hardware among the enclosure costs which include the power panel, surge protection, cable runs, professional electrical hardware/electrician fees etc. This is a full plug and play type enclosure setup for any mining farm out there. Originally built for $33000~, I'm strictly selling it at a fair hardware priced value with cutting out a lot of the fee's that you would have to pay for an electrician to wire up your own custom enclosure and the electrical hardware. Cash or Bitcoins only.
Asking $15000 Canadian firm. Also I am located around Vancouver, British Columbia, Canada.

Informative post about Feathercoin

Seeing how this Subreddit is lacking any sort of info on Feathercoins and the lack of community support we have, I have decided to start a post that would inform newbies about Feathercoin and seasoned vets on the best places to trade.
Feathercoin:
It is a Crypto Currency that was started by Peter Bushnell. It is a clone of Litecoin (This coin was inspired by Bitcoin). The Feathercoin network generates coins at a decreasing rate. It will generate about 336 million coins which is 16 times more than that of Bitcoin and 4 times more than that of Litecoin. Currently about 25 million coins have been generated.
Network hashrates, Pools, Solo mining:
Currently a mid end system comprising of 7870 or 7970 will get you abot 400 to 700 kh/s. That means that in a given day you will be mining about 7 to 13 Feathercoins on current difficulty level. However If you mine alone that is solo mining, the probability of you finding a block is hard and it may take a while before you make a coin. To counter this people have started making pools to increase the chances of finding blocks. There are many pools that allow you to have multiple workers so you can setup multiple systems and mine at your leisure. Currently some of the popular pools are:
http://www.fcpool.com/
http://give-me-coins.com/
http://www.wemineftc.com/
http://fc.ltcoin.net/
https://ftc.d2.cc/
For a full list of mining pools: http://coinpools.sdfg.org/ftc
It is highly recommended to join a pool to make mining profitable. Look at the pools posted above, look at their fee structure, their payout and make an informed decision on which pool to join.
Hardware and Mining:
Feathercoin utilizes scrypt based mining that is you can use your GPU (the Graphics card inside your system) to mine them. AMD Cards are highly recommended as they output higher hashrates as compared to Nvidia. To give you an idea of the difference a 7870 ghz edition mines at about 375 kh/s whereas a Nvidia 780ti would mine at about 224 to 300 kh/s. If you are seriously considering in investing in this venture it would be best to buy a rig that supports 6 GPU's and buy either the 7950 or the 280x as they have considerably higher hash rates and are affordable to say the least. Something one should be aware of is that mining produces a lot of heat as your system is basically running at full capacity and therefore needs a lot of cooling. People usually build rigs in the open (no case) and use household fans to cool them. Also another thing that is common is to use PCIe risers as they allow greater spacing between GPU cards and effectively help in dissipating heat. Mining uses a lot of electricity so it is best to use a schedule to mine or if electricity is cheap then 6 7950's running 24 hours a day would cost you about 12 to 18 dollars in electricity a month, maybe more depending on where you live. The software to use for mining are Cgminer (https://litecointalk.org/index.php?topic=6925.0), guiminer scrypt (http://forum.feathercoin.com/index.php?topic=961.0) and cudaminer for Nvidia cards. I would advise against Cpu mining as that is not profitable and will simply weigh you down. Invest 250 to 350 dollars in a good AMD GPU and you will be mining much more effectively.
Trading:
There are many places where one can trade Feathercoins but only a few of them offer FTC/USD exchange. Btc-e (https://btc-e.com/exchange/ftc_btc). Is one of the biggest cryptocoin trading exchanges, it does not offer USD exchange for Feathercoins as of yet but allows you to exchange for Bitcoins. Crypto-trade (https://www.crypto-trade.com/trade/ftc_btc), this trading exchange allows you to trade against the USD making it more favourable to miners however there is currently a lack of volume for FTC as of writing. Other exchanges like Cryptsy, Bter and coins-e are all good but they are heavily dependent on Bitcoins and Litecoins for now.
My thoughts
Feathercoin is fairly new and its gaining momentum, once big exchanges start listing it against the USD, the venture will become more profitable. For now it is advisable to mine as many as you can and sit on them till value improves or if you have a mining rig that is mining at 22000 kh/s (this will get you about 500 feathercoins a day) then mine the shit out of them and trade them for Btc for profit although I would recommend against this as it it reduces the value of feathercoin. Many exchanges allow you to deposit money via international wire transfers however the minimum is 2000 dollars so keep that in mind before investing real money into this venture. There are alternatives like paypal and okpay that are also accepted but not a lot of people have accounts on those so signup for a website that suits your situation.
One last ting we all need to do is spread awareness about Feathercoin, It is a miners coin and the difficulty right now makes it so much more interesting to mine. I will update this page with more information and will answer questions if any to the best of my knowledge. Happy mining

EDIT : I realized some of you might have NVIDIA GPU's and are hesitant on getting AMD. Never fear for there is a solution. If you have a motherboard that supports two or more GPU's that is you have more than one PCIe slots than follow these instructions:
If you intend to game on your system while you are mining then put the NVIDIA card in PCI slot one and buy an AMD card and put it in slot 2. Now install the drivers in the order Nvidia first reboot and then Amd second reboot. You do not need to plug in HDMI to your AMD card just leave it as it is. Now download gpu miner scrypt and select from the list your AMD card and start mining, its that easy. At night if you want to squeeze in more kh/s then run cudaminer and let it mine alongside your AMD. The best part about this is that you can be mining 24/7 on your AMD card and you will not experience any system slow down while gaming or watching movies. Remember to have atleast two workers workers created so you can mine parallel. If you already have an NVIDIA card then just install your AMD card and install AMD drivers and reboot and run guiminer scrypt. At times you might run into the issue of guiminer not starting, just delete it and re install it and it should work fine in 98% of the cases. This is for those who do not want to invest in a completely new system and would rather use their existing system. You can use cgminer as well but remember the order in cgminer starts from 0 not 1 so if NVIDIA is in slot 1 then it is -d0 -g0 and AMD will be -d1 -g1

The R9 280X experiment / mining questions

I'm a gamer who also recently got interested in bitcoin/litecoin. For a while now I had been thinking about getting an upgraded GPU to replace my GTX 460. The recent booming of the coins has convinced me to move, and I just ordered an XFX R9 280X (should be getting it some time this coming week). My plan is to make it pay for itself by mining litecoins before I begin using it in my gaming rig. Has anyone else done this before? How likely am I to succeed? Worse case scenario is I have a new GPU to game with, so I'm not too worried anyways.
I'm also potentially interested in doing some more mining if this proves successful. I would have the financial resources to drop some more serious money on a big mining rig if it turns out to be worthwhile, but I will wait to see how profitable it actually is with one GPU. I've messed around with a few different mining calculators and most of them seem to suggest that a rig made of 280X's with cheap supporting hardware will break even within 20-40 days. So if I was to scale this up and buy more hardware... Even if the calculators are off and difficulty rises further, it looks like it would still break even within 2 months. What are the most serious arguments against this? I know the coins could crash into oblivion and suddenly be worth 0.01$. This doesn't seem like such a big risk to me because if it happens I can still sell the hardware at a small loss. So really how likely is it to not break even? How many of you guys have dropped 2000-3000$ on mining equipment and ended up with a loss? Do you expect an LTC crash because of BTC becoming much stronger? Or do you rather expect a boom as LTC becomes more mainstream and gains traction at some major exchanges?
Bottom line is this : to me, this seems too good to be true, and that makes me defensive and unwilling to commit (for now). Convince me.

How to fix crashes and low hash rate on my new scrypt rig?

I need help to get past two major problems in my scrypt mining machine (see my config at bottom).

1 problem is system crashes during mining, even with low hash rate

2 problem is the low hash rates. 280x running at 400 k/hs and R9 290 at 180-400 k/hs

So far I have tried mining on Windows 8.1, Litecoin BAMT Linux and SMOS Linux with much luck. On Windows 8.1 I have gone through tons of AMD Driver versions from 13.1, 13.11 beta v9.4, 14.1 beta, 13-12, and bunch of other versions. Even tried couple of DDU clean ups. I have also tried different iners like cgminer, bfgminer, etc. Note on windows 8.1 I can't see GPU temp either. However, the hangs and low hash rates persist. One of the main issues is I can't get around play around with miner settings due crashes.
On linux at least I can see GPU temps. But from my testing the system still hangs when running at 400 k/hs on my two R9 280x or 180 k/hs on R9 290. My setting for above on cgminer was (2x 280x and 1x 290 at the end):
cgminer.exe --scrypt -I 12,12,12 -shaders 2048,2048,2560 --auto-fan --target-temp 65
Here is my hardware config:
MSI Z77A-GD65 Motherboard(highly recommended on bitcoin.org board)
Intel Celeron G1620
Corsair RM 850W
G.SKILL 8 GB (4GB x 2)
Sapphire Radeon R9 280x
MSI Gaming R9 280x
XFX R9 290x R9-290A-ENFC
Anyone got any suggestions on what to try next? Seems like very hard to mine effectively, for me atleast...

Planning on building a mining rig, would appreciate if I could get some help.

First of all I can't really decide if it's better to go for a bitcoin or doge/lite rig, but my stomach tells me to go with doge so I guess that's what's gonna happen!
I'm a complete newbie when it comes to this, but I've been looking around for a while and want to give a shot. I'm planning of going with 4x XFX Radeon R9 290X, should I perhaps go for the 280X or completely another one? I can get the 290X for 615$ each and 280X for 415$ each. I'm not entirely sure for the other parts but I had a look here http://www.coinminingrigs.com/ and guess I would take something similair. I'm guessing I could get 800 kH/s out of the 290x and 700 from the 280x, does anyone have some exact numbers on how much is possible (I had a look here https://litecoin.info/Mining_hardware_comparison but getting way too confused with all the different 290's and 280's lol).
Any input is appreciated, my budget is 2500-3000 (+-150)$.
