Those 5970 really blow the hot air out the 'front' of the card, so will you be mounting these new rigs in a reverse direction then all the others?  so the house fans blow the air from back to front?

All of the hot air on my 5970s blow out the metal end of the card where you plug in the monitor. If you look at the bottom of the rack in the picture above, you can see they are sitting reverse from the rest of the machines. All of the other cards rely on pressure in a normal computer case to help blow the hot air in the right direction so when they are in the open, they don't do what they are supposed to.

What mobos do you use ?

Hello

The cost of Electricity is 0€ (datacenter of my work)
Cost of Pentium 4 machine 0,1€ (obsolete machines of my work)


The mobo of core2 support a pci x1, but the case of to small for 3 cards, and the machine without case not is possible ,  solution... other machine. and the next card mount into other Pentium 4 a 0.01€ cost , the AC power is the 300W but the 5830 work fine.

One of three rigs:

-AMD Sempron 140 CPU
-G-Skill 2GB DDR3 RAM
-Gigabyte 990FX-UD3 (great motherboard, cheap and has good PCI-E layout)
-Western Digital 80GB Hard Drive (WD800JD)
-AMD Radeon HD 5970s (the new OEM ones that came out, solid overclockers)
-Cougar GX-1050 (great efficiency and rail design, only has 6 PCI-E cables though)





I have 3 Scythe Slipstream 120mm 1900RPM fans blowing cold air down on the GPU chips, they make a huge difference in VRM temps so the cards don't throttle down.  These fans are quite amazing, great price, great CFM, and acceptable dBA (nowhere near my 5970s @ 70% fan speed).  I also have a Honeywell table fan circulating the air.  The whole rig and cooling solution only uses 700 watts so mining is still profitable, for long-term mining I focused on energy efficiency first and foremost (even over cooling or hash rate).  This rig does 1520MH/sec (380 MH/sec for each GPU core).  It sure doesn't look pretty but it gets the job done, the mobo is laying on some computer case sides from junked computers I found by the dumpster  Shocked

The Catfish Bitcoin Mining Shelf Rig Mk II - nearly complete:



Remaining things to do - remove CD-ROM (was only there for installing Linux on the three boards), screw in another wooden support for the hard drives, secure the PSUs where they currently sit (under the temporary boarding that the HDs sit on), and add two front doors - open mesh (like a rabbit hutch) or perspex frame with a single row of PC case fans horizontally down the centre, to blow air *onto* the top of the GPUs.

The aim is to get a furniture-like modular piece that can be moved anywhere and vents the majority of the hot air upwards, where it could be collected in an airbox and extracted using an extractor fan (or used to heat the house).

This one is consuming 2000W at the wall and is running really cool for air - haven't started overclocking in earnest yet but there's loads of headroom to come. I've finally come to a design I'm satisfied with, and will be rebuilding my Mk I Shelf Rig into the same design (I've got another two boards and 12 cards to use)...

...so I give in to the rhythm, the click click clack
I'm too wasted to fight back...

Wow cool that is a nice setup - where do you intake/exhaust the power supply fans though?  How many psu are you using?

If you're talking about mine, firstly thanks Smiley - otherwise, the design is modular.

Each module is a Gigabyte microATX board with 4 PCIe slots, and 4 GPUs on extenders. This fits in a cube, so there are three cubes in a row on the second shelf of the three-shelf unit.

The top shelf has the middle slat removed to allow hot air out.

The middle shelf has the middle slat removed to install three domestic extractor fans, which blow air UP into the electronic cube modules. The logic boards and GPUs all use extender cables to drop the inputs (ATX 24-pin, ATX12V 4-pin, and all the PCIe 6-pin GPU power cables) down below the second shelf.

The bottom shelf has all three slats intact, and is where the PSUs stand. Each PSU (one per module) stands on its side so it's pulling air in horizontally and blowing air out of the front of the unit. The leftmost module has 3x 5850 and 1x 5830, hence is using an 850W Cooler Master. The middle module has 4x 5830 and is using an 800W Corsair. The rightmost module has 4x 6950 and is using a 1000W Cooler Master.

I want to put in a sub-shelf for the hard drives - currently there's a random piece of MDF board sitting on the PSUs, and the HDs are sat on top of that. However, there's PLENTY of room on the bottom shelf - the middle shelf is somewhat cramped for access Smiley but the PSU level is not. It runs surprisingly cool, but is the result of a LOT of R&D (i.e. previous failures, and valuable help from a member of the MMC pool I use).

I'm going to break the habit of a lifetime and actually *finish* this one *completely* before building another one Cheesy

Catfish my man Smiley Looking nice indeed. Them cards look really close, sure heat isnt a issue..... What are them cards? i can see the wood blocking some of the air holes on some of them completly (to the left), I can see issues man Smiley

YOu got me itching want make another one now Smiley

^^ Best temperature of all my designs so far! Loads of help from a chap on the MMC forum though. Three domestic extractor fans blow air up from the second shelf. Temperatures range from 55˚C to 77˚C - all cards very mildly overclocked to 850 core just to see if it works.

It's been running since I finished last night - temps are well under control. The entire airflow was worked out to work *with* natural convection, and not fight against it like my previous attempts. The system even runs without the extractor fans, but the 6950s get a bit toasty.

The cards are, from left to right:
5830 XFX new design
5850 XFX Black Edition
5850 Sapphire 5-heatpipe 990MHz overclock monster
5850 Sapphire Extreme
5830 Peak Value
5830 Peak Value
5830 Peak Value
5830 Peak Value
6950 XFX mk2 no BIOS switch
6950 XFX mk1 with BIOS switch
6950 Sapphire big-fan no BIOS switch
6950 Asus DirectCU II overclock monster

I want to finish it but I've got another one to build!!!! Takes a day to build, though the design took ages. The hardest bit is the aluminium GPU bracket support - you NEED to get that absolutely *bang* on - half a millimetre out on a screw hole and the card will hang at an angle and touch another GPU.

Believe me, temperatures are NOT a problem... there's more space between each GPU than inside gamer PC cases, remember...

The shelf kit costs £14 from Homebase. Or was it £12? Whatever, it's cheap. Smiley

I dont know anything about these things (not much anyways, is it ASIC?FPGA? heard a few acranims). Can you lead me to some info on this kind of thing as im very interested but dont understand how it all works etc. I want to know Smiley

^^ With similar curiosity - I have two questions only:

1. How much does a complete kit cost (i.e. board, heatsinks, necessary special cables, etc.)?

2. Can I run the mining software on a pool without needing to know VHDL or assembly-level code?

Actually, there's a third question. Assuming that this is an FPGA board, and from the hash rate you quote, it sounds like a fairly decent spec FPGA - how much does the software licence cost in order to load the BTC Miner gate logic onto the FPGA? I don't know much about this level of engineering, but have heard many stories about requiring proprietary software to load your own 'code' onto the FPGA itself, and that this proprietary software costs an absolute fortune.

I'm mining for the money (not that it's particularly profitable right now) so my mining rigs would be considered 'business' in court (indeed, the hardware was bought by the business I own). So using 'evaluation' or 'academic' licences would be fraudulent.

I'd love an FPGA setup (after seeing the number on the watt-meter attached to my Shelf Rig above) but I have a feeling that the FPGA-loading software costs 4 figures. And since I can't design my own gate-level logic, I wouldn't have any use for said software other than initially loading up the bitcoin mining logic.

Doing it for fun would be great - I'd like to purely to experience a new type of hardware and software - but I'd feel uneasy as hell about ripping off a software package worth thousands. I can't lie that I'm 'academic' or 'evaluation' if I'm actually making money using the damn thing...

(by the way, this is only my opinion, and not casting a judgement on anyone else here - prejudice isn't my style, especially when I have no information)

It's an FPGA miner. There are two FPGAs on the board (Spartan 6 LX150-3) and they communicate with the computer over USB. We designed this board and will be selling it very soon.

^^ With similar curiosity - I have two questions only:

1. How much does a complete kit cost (i.e. board, heatsinks, necessary special cables, etc.)?

2. Can I run the mining software on a pool without needing to know VHDL or assembly-level code?

I don't know much about this level of engineering, but have heard many stories about requiring proprietary software to load your own 'code' onto the FPGA itself, and that this proprietary software costs an absolute fortune.

Good questions!

1. The basic board is $610 $580, including heatsinks. You need only a USB mini B cable and a spare Molex "peripheral" power connector, or a basic AC adapter (aka wall wart). The boards along with cables and power supplies will be for sale on Cablesaurus.com.
2. Running the software is as easy as running phoenix or similar mining software. You just have to download the code and plug it in. Right now, the software isn't as slick as phoenix or especially GUI miner, but that should get better with time.
3. You only need an expensive software license if you want to develop new VHDL/Verilog code. The Xilinx software will synthesize the source code into a "bitstream" that is loaded onto the FPGA. The bitstream is the equivalent of a binary for a computer. As long as someone else will build the bitstream for you (we will), you have no need for the expensive software.
