Title: Building a mining computer Post by: thehulkk on April 26, 2013, 04:51:48 PM Thanks to everyone that has helped me. I decided to go with the radeon 7950 cards instead of the 7970. It saves me $200 and with a difference of 0.02Mh/s/$ lower. I made my calculations with the 7970's I can hash up to 1400Mh/s if oc, with the whole system price of $1100 gives me 1.29Mh/s/$ spent. With the 7950's I can hash up to 1200Mh/s oc, with a price of about $930 for the whole system it gives me 1.27Mh/s/$ spent. So it's not a big difference it saves about $200 dollar. I will use ubuntu 12.04 LTS on a 16 GB thumb drive I already own.
I changed my mind, I will use milk crates, it looks pretty easy to do after reading some guides. Also swiched from msi 970 mobo, to asrock 970 and switched saphire vapor x to xfx. http://pcpartpicker.com/user/thehulkk/saved/1wd1 (http://pcpartpicker.com/user/thehulkk/saved/1wd1) CPU: AMD Sempron 145 2.8GHz Single-Core Processor ($35.98 @ Outlet PC) Motherboard: ASRock 970 Extreme3 ATX AM3+ Motherboard ($74.99 @ Newegg) Memory: Patriot Signature 4GB (1 x 4GB) DDR3-1333 Memory ($28.87 @ Amazon) Video Card: XFX Radeon HD 7950 3GB Video Card (2-Way CrossFire) ($263.98 @ Newegg) Video Card: XFX Radeon HD 7950 3GB Video Card (2-Way CrossFire) ($263.98 @ Newegg) Wireless Network Adapter: Encore ENUWI-1XN42 802.11b/g/n USB 2.0 Wi-Fi Adapter ($9.98 @ Outlet PC) Power Supply: Cooler Master Silent Pro M2 720W 80 PLUS Bronze Certified ATX12V Power Supply ($74.99 @ Newegg) Total: $752.77 Title: Re: Building a mining computer Post by: FlappySocks on April 26, 2013, 05:01:41 PM A lot of money for a "broke college student"!!

I've decided to build my own mining rig, and for about $800 I included everything I needed with the best graphics card for mining radeon 7970. I would like some constructive criticism on how can I improve this build for better mining. This is right in my budget, but I could expend up to $900. I am going to use Ubuntu instead of windows.

Get rid of the AS5, more waste. Cheaper hard drive unless you already have it Cheaper wireless, must be one If you're going 1 GPU then you can drop down to literally 450W PSU Optical drive, why? I don't even have one [plugged in] on my main tower. Consider swapping down to 2x7950s, 1000MH rather than 600 and more price efficient. A lot of money for a "broke college student"!! With ASIC's coming online soon, you will never get your investment back. There is a difference between having money in hand and owning that money. For example if you were -$1m in the whole and I gave you a $2m loan, you'd have $1m to hand but still owe $2m.

Title: Re: Building a mining computer Post by: scifimike12 on April 26, 2013, 06:50:56 PM There is no way in hell that CoolMax PSU will power either of those 7970's. It's junk.
Crossfire cables do come with the video card but are unnecessary for mining.

Be wary of going such a cheap case in that you will probably have to buy 2 or so 120mms fans.

Title: Re: Building a mining computer Post by: thehulkk on April 27, 2013, 02:30:08 AM I'm kind of undecided between the gigabyte and saphire vapor x.
Title: Re: Building a mining computer Post by: phillyj on April 27, 2013, 03:11:06 AM drop the HDD and get an 8gb flash drive to load up linux. Forget the athlon and get a sempron CPU for $30. You can probably find cheaper ram, without all that fancy heatsink stuff. Forget the case and use a milk crate.
You do want to save money, don't you? From the rumors around here, there's no way you can profit nowadays. I'm building for fun; I don't expect much return. Edit: PSU is important. Get the good ones with single 12V rail. Title: Re: Building a mining computer Post by: ISAWHIM on April 27, 2013, 03:18:24 AM I wonder if the crossfire adapter comes with the graphics card. It isn't needed... unless you are going to "play games" and try to use both cards as "one card"... Even then, it is a wasted connection, unless you have an ultra-HD resolution.

If not, get a cheap 32-64 SSD that is older and used... they draw 2-4W running, and 0.2-0.8W idle... unlike a HDD which is closer to 18W-80W... Also, if you do not have the CPU and MOBO yet... get one for a pentium (T) format chip... EG... Celeron G650T (Not G650)... the (T) = "Low thermal design", thus, 7w-35W idle/operating as opposed to normal chips which are 18w-85W. (Eg, smaller fan for cooling, less power draw, more power to your GPU's) Title: Re: Building a mining computer Post by: thehulkk on April 27, 2013, 03:36:51 AM I'd still recommend dropping down to 7950s.

I haven't bought the parts yet, I'm gathering the money. For the person that told me to use a milk create, I'm not sure I'm going to have the time to figure out and build a crate for all the parts. Alsomy wife wouldn't like the sight of it Title: Re: Building a mining computer Post by: crazyates on April 27, 2013, 03:48:22 AM http://www.newegg.com/Product/Product.aspx?Item=N82E16817171067 (http://www.newegg.com/Product/Product.aspx?Item=N82E16817171067) Ya that PSU is fine, and should handle 2 GPUs no problem.Milk crates are great if you're going for absolute cost saving, and you can shove it somewhere out of mind. If you're only mining with 2 GPUs, a PC case should be just fine tho. Remember, it's still going to have to be secluded, as the fan noise can be pretty decent. Your wife won't like the constant humm. As for Win vs Linux, it doesn't matter as far as hashrate is concerned. I've used both, and they each have their pros and cons, but they're pretty minor, and mostly dealing with remote access issues. As far as the actual mining software and drivers go, they're pretty much exactly the same.

But it's your choice, go with AMD Sempron or the Intel Celeron G5xx or G4xx procs. These are cheaper and use less power. There's a sale on Newegg for cheap Crucial 4gb ram.

I would recommend the following, but also note that you might not recoup your investment. You can always sell the cards to gamers for $200 each, but BTC is gonna get more and more cost prohibitive. LTC? Not sure yet.

What i'm going to do is buy both the saphire vapor x, but one of them will be bought by a relative, so I can get both discounts and games decreasing the value by $200. I rather keep the mobo I selected, it has more pci conections just in case i want to add more cards to it later on.
