Welcome! Please tell us more about your system, like how many PSU's and so on!
8x Crossfire? Quad would be plenty, AMD's crossfire limit is still 4 GPU's i believe!

I belief that you would need modded drivers to get past the 4GPU limit (2 per card) and a bigger PSU based on this load power results for a single card http://www.anandtech.com/show/2877/16 each card comes close to 300watts under load.

wow 0.o

but seriously, 8xcrossfire cant be done, max is 4 gpus, in this case 2 5970s since it's a dual-gpu card.
Might be a monster folding/boinc rig though with all that computing horsepower. :D

Not really! Browse the web, look for modded drivers is the steps I would take. You realize that you would need one serious CPU setup to be able to keep up with those cards.

+1 lol return 2 cards as they are useless, the most you can use is 2 x 5970's as each card is 2 gpu's crossfired already. 2x2=4. you cant have more then 4 gpu's in crossfire period, stop asking silly questions.

Sorry but you will not get passed the 4 gpu limit period. First there is a psu limitation and second the software limitation will stop you period. DX9 through 11 can only use a max of 4. It isn't like openGL or Glide that can use more. You should have done your research before buying two of them. As for the rest good riddance some of you act as if you have much more experience than me then yet not get this.

DX games and applications max out at only 4 gpus.

no one needs. more 2 than 5970s in crossfire, thats plenty of power,

Thats using their compute functionality for password cracking, that is not trying to get them all to work as one in crossfire, most GPU compute apps are expandable, especially something for password cracking, it would be willing to take advantage of as much as you could feed it, but for games it cannot be done, you just wasted money, enjoy.

You do realize that those links you keep posting are referring to a brute force password-cracking program and have no relation at all to 3d graphics drivers in any way?

Wow more money than brains huh? What were you thinking when you decided to buy 4 5970s, exactly? What are you trying to do with this?

Estimated times for SL3 code calculations

GPU speed estimations for MD5/SHA1/Office 2007/WPA/WinZip/SL3

These are only estimations, depending on GPU architecture results may be very different in reality. But ratios should be OK within same family.
GPU prices more or less valid for autumn 2010 (newegg.com used).

Note that SL3 "solutions" based on stolen ighashgpu's code doesn't support 54XX/55XX/56XX and 6XXX GPUs at all.

Again, using the GPU Compute functionality, not the graphics functionality.

Then you arent using crossfire. Crossfire is used in games to make the GPUs behave as one, GPU compute doesnt try to make them behave as one because it really doesnt care.

The max for crossfire is 4 GPUs... 5970s have 2 GPUs each so you're trying to make it 8 GPUs. You cannot do that.

Using Direct Compute, as in using your GPUs to crunch numbers, is possible. You can use as many GPUs as you want for that. But it has nothing to do with crossfire. Many smaller "supercomputers" use this method.

yes and 4 dualgpu graphic card are too expensive,one, and theres tesla video cards for scientific purpose and so on, so theres card that are better than that for the same price

I am talking about the same thing as you: the raw computing power for GPGPU (what you call "scientific", or non-graphic) applications is higher on ATI cards than Nvidia Tesla cards.

Whether we are talking about integer performance, single precision FLOPS, or even double precision FLOPS (where Nvidia used to lead), ATI is faster these days:

ATI HD 6990 = 1275 double precision GFLOPS
ATI HD 5970 = 928 double precision GFLOPS
Nvidia Tesla C2070/C2050 = 515 double precision GFLOPS
Nvidia GTX 580 = 791 double precision GFLOPS

For integer and single precision FLOPS, ATI is about 2x-3x faster than the high-end Nvidia gaming (GTX) or scientific (Tesla) GPUS.

sounds like something that Bill Gates said... and now is laughed at for... no one will ever need more than 640k of memory!!! :/
