9800 GX2 only uses single core!

I bought a used KFA2 9800 GX2 and I'm almost beginning to think that it's faulty
I've updated driver to the latest 177.41 Vista 64bit and I've tried many different settings in nVidia control panel but no luck...

3DMark still gives me score of about single core from 9800 GX2

I've checked temperature and fan speed with gpu-z

I'm not sure if both should have fan speed but one of them has fan turned off
I've used rivatuner to manually set fan speed to 100% and ran 3DMark but I still get same low score with 9800 GX2


I have Q6600 overclocked to stable 3.3GHz and use windows vista ultimate x64
Does anyone have any idea what could be the problem here if the grahpic card is not faulty?

I got a OCZ 1000W PSU just in case it's the PSU not providing enough power but I don't know... I have OCZ 600W PSU right now
 
Do you have SLI enabled? I says it is in the gpuz screenshot, but it seems finicky about detecting it correctly.
 
in nvidia control panel, I don't see anything that specirically says

"enable/disable SLI"

but I see "set multi-GPU configuration" and it's already set to multi-GPU mode
 
That should be right. Try enabling th show sli indicators under the 3d settings. When you run a game it should show a green bar indicating the sli usage.
 
How do you do that? I never seen that green bar. I have the same system settings as luv2sd and i have the same problem. The control panel has multi GPU but nothing about SLI config.

You might be CPU-bound at the default 3dmark resolution with that card.

i doubt very much if he is CPU bound, i get a score of 13,636 with 3Dmark06 with the system in my signature below so there is something wrong somewhere. on ATI cards the dual GPU's are always enabled. how much system memory you have installed?
