Wow, i thought that was well hidden in the past.

Oh God. Now you have me wanting to compile the bitcoin software for my NeXTStation. Where is the C code for a good POSIX CPU client?

Seriously. If someone PM's me a link for simple code, I'll post a picture of it hashing. If I fall into a pit of boredom I'll even bum the code so the SHA256 runs on the 56001 DSP. That should get a few more dozen hashes/second...

C

(Edit: I have a card like that in my pile somewhere. From a Dual systems UNIX system; wait! I could compile the bitcoin stack on my DEC Professional/380! I wonder if it will fit in 64kb of memory or if I have to break it into segments and swap....)

Not so simple, and you're probably going to have to rewrite major portions of it but...

Really cool hardware, love it!

very nice looking setup, good job.

Jesus, you have a portable air conditioner inches away pointing the air flow right into that rig and it still hits 78C? Lets cook some eggs!

It is stock clocked as i see and there is no gap between gpus. Personaly i dont think that cardboard on the cards helps, exact oposit.

I agree. I can feel a lot of hot air rolling up and over the topmost card on my rigs like that. Your fans are not going to last long like that, I know from experience. I'd try to get them out on riser cables ASAP.  

Managed to get 6 280x cards working at 700kh/s+ stable. These saphire Dual-x's are different than the others I have, two 8 pin power plugs like a 7990. I like the old Dual-X better since they hash at 750 no sweat, but this cooler looks beefier. Settings are completely different, if anyone wants them let me know.

@pontiacg5
would you be so friendly to post your complete setup. i am very interested to that.

Nothing special really, just a ivy bridge celeron and a z77 mobo with 7 pcie slots. The mobo is a z77a-gd65, but a cheaper z77a-gd44 (i think?) works with 6 cards... Has to be ivy or 6 won't work. There's 3500W of power under my rig now, but two of the supplies are cheap 1000W'ers. They run 6 7950's at 1.125V, but not 6 280x cards at any voltage. I use a EVGA 1500W to supplement the other two supplies. I ordered 1300W and 1000W evga power supplies, one will power the mobo and 3 cards, and the other will power three cards alone. Ought to be plenty of headroom, I expect 275W from each card.

The rig is running xubuntu, as I wasn't able to figure out how to get 6 280x cards running in W8. You have to use the beta 3.11 drivers for Cgminer to "see" these cards, they show up as 7900 series with old drivers but won't ever mine.
Anyway, 3.11 beta drivers from AMDs site work pretty well. I did a bunch of reading on the net, and these settings are the best mixture of what I was able to find. I should say that these settings might be completely useless to you, but they should be a starting point. These cards all act different, I'm starting to think any results otherwise are just gamblers fallacy! Either way, I won't charge you 1 BTC for my config because I'm not that much of a douche 

You will need to tweak the GPU clock speed for each card, most of mine are somewhere between 1025 and 1045.





I can lower the fan speed to 80% and still maintain ~75 degrees. I've got some work left to do with ducting and more permanent fan mounting.

thank you very much! i think i will try to copy your setup a bit as it seems to be very nice  . i have ordered yesterday a rig from open openrigs.com and i will order this stuff:

4x Sapphire 11221-00-20G Dual-X amzn.to/1dIoFTp
1x Gigabyte GA-Z77X-D3H amzn.to/1fUdzL9
1x Intel BX80637G1610 Celeron Dual-Core Prozessor (2x 2,6GHz, Sockel 1155, 2MB Cache, 55 Watt) amzn.to/1fUdAyT
1x Corsair 4GB DDR3 1333 MHz amzn.to/1b4NSnv
1x Corsair AX 1200(i) amzn.to/183tRP5

I have somewhere an old 32GB SSD drive or I am thinking about a 16GB USB3.0 stick. I will also add 2x R9 280x and 1x Corsair 1200w later. But still thinking if these PSUs are the right decision. When everything arrives and I start mining LTC i will make some pics. I will also contact you to send you some LTC for your help!

Those sapphire cards are very nice, the ones with the blue LED bios switch. I have two of those and they both pull 750kh/s really easy, I even moved them between multiple systems and OS's and they always perform about the same. They like tc 8192 gpu-e 1080 lookup gap 2 worksize 256 -g 2 and I 13. I have a Corsair 760i on the machine running these cards...




I wish I could find more of those here, but they seem to be replaced with the exact same model number but with "BF4" added (they do come with the game now.) The cooler no longer cools both the RAM and GPU, there are individual RAM heatsinks as well as VRM heatsink. These cards are a bit wider because of that, plus they have 2 8x pci-e power plugs.  Cards act entirely different, totally weird!

Anyway, good luck with your build. Let me know if I can help!

Crazy mining! Our friends at ModWithMe sent us this picture of a mining farm containing 8x Club 3D HD 7990 watercooled by EK Water Blocks. Another 4x HD 7990 will be added soon so there will be a total of 12x watercooled HD 7990's! A huge 50 liters(!) cooling reservoir is being constructed at this moment. More pics will follow.

Do you have an insane mining set-up? Feel free to share your pics!
