Bad 3DMark06 Score (6800 marks) with 2x 8800GTS 512 in SLI

even 1 card will get a higher score than that.
something is Wrong.

before i give some trial and error options I will ask some questions.
Did you build this pc yourself?
(i assume so from op)
Did you use the pci-e power from the power supply unit or the dual molex into pci-e power for the cards?
Have you got the latest bios for your mobo?
are the cards Identical eg stock and over-clocked?
Here is a series of things I would try:

1 Check that each card is seated properly, this is probably ok, as sli has been detected in windows. still a re-seat can sometimes fix troubles.

2, Use the pci-e power cables on the psu, not the molex splitter adapters that came with the gfx cards.

3, try games with the cards in SLi

4. download ntune software, and check not only the gfx temps but go to advanced and set up for single display performance mode.

5.Download gpu-z and check bios numbers and info for the two cards and check that they match.

6.as nesquick suggested do a virus sweep.

Maybe one of the cards is cactus. Try each one by its self and see what happens.

even if one was dead i would assume he would get a score in the 12k's

IMO best thing to do would be backup everything do a clean install and rebuild everything from scratch making sure its all plugged in correctly and no short cuts were taken :)

Have you checked the cards frequencies to make sure that it’s not underclocking for some random reason?

And don't neglect the PSU, it might be the problem too.

I'm at work at the moment so I can't do a lot but I can tell you that both are using the power from the PSU plugged into the cards.

Yes I built this system myself from scratch. It's only about 2 weeks old.

The cards look identical. I even labeled them with a marker so I didn't confuse them.

I haven't updated BIOS so I'll try all above suggested things later this evening. Keep the suggestions coming guys, I really appreciate the help.

I've taken out the cards physically and tried each one seperately. Strange things ensued...

Card A only: 12328 3DMarks
Card B only: computer turned off during CPU test.

I tried Card B three times. First time it made it to CPU test 2 before computer powered off. Second time it only made it to CPU test 1 before powering off. Third time was the same as the first.
All tests were on par with Card A's fps though.

I put Card A back in and tested it another 3 times:

Test 2: 12141 3DMarks
Test 3: Powered off during CPU test
Test 4: 12257 3DMarks

Very Strange.
The 3d marks seems more correct though.
So did the pc power off with Card A and Card B?
Have to confirm this so we can further determine if its a card or cpu problem.

Your video cards seem to working fine. I'd point the PSU as the issue here too. I'm looking at the 12V railings of your PSU

From
http://www.anandtech.com/casecoolingpsus/showdoc.aspx?i=3046

12V1 (18A) - CPU1
12V2 (18A) - CPU2/PCI-E(A)
12V3 (25A) - ATX 24-pin/PCI-E
13V4 (25A) - B4P/SATA/PCIE (B)

Total = 62A, 744W

doesnt matter what certifications or rails it has fact of the matter is a working one of that model will supply more than enough power for your system hence why my money is on the psu as the odds of a malfunctioning cpu is second to none. as for the mobo it could be that so if you can test only the bare minimum of parts on a known to work psu and it still is screwing up then i would say its the mobo.

Ok after a long delay I've tried diagnotics again. This time I hooked up an old CRT as a 2nd screen and had everest home open on that, watching the voltages as I ran 3DMark06. But this time 3DMark didn't cause my PC to turn off.
I've tried a couple of days in a row, running it once or twice. Then today I ran it 5 times in succession, and it ran fine. This is still with just the one GPU in mind you.
The voltages were flicking between 11.97 and 11.90 on the +12V for the first few days then today I saw it drop to 11.83 and back up to 11.90, where it has not moved, no matter what I'm running.
Is this too low?

Sounds like it's only running on one card or something similar to that.

No it's normal for the voltage on a rail to not be exactly what's specified, however it shouldn't be far from it, which it's not.

Are you still getting the bad 3Dmark score with 2 GPUs?

Ok i've run 3D Mark again with 2 cards in.
13362 3DMarks

An improvement overall and a huge improvement over when I last had two cards in. But it's still not what i'd expect from 2 8800GTS 512's.

Since I last had 2 GPUs I've upgraded to XP Pro from Home. Did a reformat and moved a power cable away from the bridge (just in case).

Could it now be a case of it bottlenecking somewhere else?

Well... That score is much more acceptable and normal. If you want a higher score, then you have to start overclocking your CPU. Get it to around 3.2GHz and you should get over 15k.
