You know that you don't need the crossfire bridge for mining right? Unless he's running Windows and doesn't have or want to use dummy plugs. Crossfire hurts your performance when mining. People use dummy plugs because they have no choice. When I had 4x crossfired it was constant problems. I had no issues with performance. I used it because its easier than using dummy plugs and works just fine. I do my testing under windows which forces me to use those cables. Plus it looks much nicer and allows the person to have a high end gaming pc along with a great miner. Plus the bridges dont cost me anything, i wa getting 400mhahes/s from each card at 900core. Was it suppose to be higher? I call BS on this one. It is very hard to believe that this 4x sandwich does 0.4 Ghps per core for more than 1 minute in a row. Maybe with exception of some weird setups with room refrigerated otherwise and even than it is highly doubtful. Video on youtube or this is a fake. i am running 2x 6970s @ 905MHz/170MHz gpu/vram respectively, and they push 401Mh/sec each... http://www.youtube.com/watch?v=m56SfTZeuJo[it may be a little hard to read]

For those who are interested I have a quick video:
http://www.youtube.com/watch?v=TBXBB5sy5sA
Hi guys, Those who know of me will know I have a 6 rig setup of 21 XFX 5870 cards. Ive been meaning to put up some pics but never had the chance, Ive included a few pics below. Each of my 5 main rigs have the following spec: ZX1250w OCZ psu athlon dual core II / Sempron 140 (unlocked core with motherboard) @ 3.6ghz Asus 890fx motherboard (by far the best board ive ever ever used) 4 x 5870 XFX cards (o/c to 970 core, 185 mem) 2gb corsair ram 750gb HDD (size wasnt needed but they were on offer, if usb 3.0 was cheap i would have used thumb drives) artic silver 5 paste on all gpu's and on cpu heatsink (significantly lowered temps on cards, using even better paste wold be even better) 2 x extenders from cablesaurus.com 3 x dummy plugs 3/4 x 120mm fans I have one stand alone pc with the following specs: 500w psu intel i3 (o/c) 3 HDD x 1TB 4gb g skill ram 1 x Refference 5870 (amazes me this card does) The one thing im proud most of is my polystyrene gpu holders Sounds stupid but without hanging getting those bastards to stand up straight in an open air rig is the gayest thing ever! I use Phoenix Rising front end GUI as I love the fact it hammers connections when server goes down or my internet has a hiccup. Speeds so far for all the XFX cards varies between 350 and 430 MHash/Sec and for the refference card I get a stable 440 Mhash, total being around 8 Ghash. For those who want to join me in mining you can catch me on www.mineco.in where i mine under the same username. That server is the best Ive used as the owner Wuked is a brilliant guy, keeps the servers running with no problems and is quick to rectify any big issues you may have. Hopefully next few days we break 100 Ghash stable! Btw yes thats a 3D tv, playing call of duty and gran turismo on it is the best thing ever after a hard days mining. PS Sorry I have the shakes

Here's my 4x5830 rig. Two cards are running directly on the mobo, two are running on PCIe adapter cables in the second tier. Yes, the skeletal chassis as such is an old table that was taken apart and put back together. I've since moved this setup from my dining room table to a small desk in the basement and it has a box fan on one side blowing through the videocards (the temps are quite low). Each card is putting out 310 MHash/s for 1240 MHash/s total. Oh, and the OS is Linuxcoin running on a USB flash drive.

Hey Cyper, What script and/or miner are you using in that one pic showing PuTTy?
Autominer - very handy.

nice, but how is there no risk of short circuit with all that metal?
Erm, no water or bare wire all over the place? Most computer cases are made entirely of metal, and have well worked that way for quite some time. no, because those graphics cards look like they are resting directly on metal, and what is protecting the back of the motherboard from touching the metal frame? this is not a computer case. The MB/PSU are in the wooden base and the graphics cards are hung from the aluminium at the top and rest on a strip of adhesive backed foam on the bar. BB.

Just took some pics, for writting a tutorial so i'll post my rig here also 3 x 6990 = 2600 MH/s - 2700 MH/s Damn how did you get this thing to run stable at 2600mh? Must clocked the crap out of it. I have 2x 5970 and only able to run it at 1300-1400mh

Thanks, it's a Danger Den Tower 29 case....custom. I was using it for another project but its so big and roomy I thought I'd use if for this

So I've clicked through all 30 pages and I DIDN'T SEE ONE SUBMERGED SETUP. I am dissapoint.

I'm simply not necessary. I'm running my cards just about as fast as they can possibly go. My secret? No case + box fan. Which is much, much easier than a submerged setup, I assure you.

Everything I have read about submerged PCs assumes that the PC will have brief periods of use followed by extended cool-down periods. To make it work in a mining rig you would need to set up some sort of pump and radiator system but if you are going to go to that length you are better off just water cooling. Also, submerged components are more difficult to resell or reuse.

I'm running mainly reused old LGA775/AM2 stuff, except the ITX box with that uber 1337 keyboard. Didn't had to buy anything besides GPUs and two cheapo Celeron Ds (underclocked to 2 GHz / 1,1 V). 5830, 5770, XP 32: http://img15.imageshack.us/img15/1835/rig1h.jpg5770, 5750, 5830, Natty x32: http://img810.imageshack.us/img810/172/rig2h.jpg5750, doing some server stuff too, Wheezy x64: http://img171.imageshack.us/img171/551/rig3.jpg5750, 5770, Wheezy x64: http://img9.imageshack.us/img9/3826/rig4g.jpgI promise, I'll buy some decent cases if this still gives some profit in 3-4 weeks.

I think that this is the design of case that i want for my cards, i'll be building one like that tomorrow ! After building it I found just one flaw with the design: the PCIE riser of the last card is being blocked by the PSU (check the picture), which restricts the spacing between the cards. They currently sit at 5cm between each other and I wanted to space them even further apart. But then again than might not bring any better temperatures, so its questionable if wider spaces are needed. If you want to space them more just either make the case wider so the PSU goes more to the right or put the resting planks for the cards higher so that the riser does not touch the PSU.

Also, submerged components are more difficult to resell or reuse. I wanted to do one, but just the mineral oil alone will cost $70-$100 (about $15-$20 a gallon), plus the cost of the pump, radiator, tubing, and container, etc. Then you have to worry about leaks, weeping oil (up the cords), and a big mess if you have to fiddle with any hardware. IMHO, you MIGHT come out ahead on a large scale if you have enough oil, but you still have to cool it

Well I'd have a large enough case to enclose several motherboards etc. and then have all cables connect to a breakout panel to prevent weeping. As far as cooling goes, you simply pump the oil out of the case and down an inflatable slide/kiddie-pool. a pump at the end of the slide in the kiddie-pool returns the oil and completes the circuit. As far as cost goes, you simply have several women in white undergarments slip and slide down for several hours, wrestle, gyrate, and collect fees from onlookers in order to recoup the cost of oil and additional hardware. After several weekend the mining rig will more than pay for itself, even with several difficulty increases. Coffee filters can be used to collect any lost body piercings or hair scrunchies that my get lost along the way.
