3XS White Tiger BIOS Settings

[MrBear1987]

Hey people,

If required, build number is: 31890

Got a few issues!
Updated the BIOS on my system, which reset defaults, also prevented the profiles from loading.

I've been tinkering around with getting a stable CPU overclock back, am almost there I think.
Unfortunately I've managed to overwrite the profiles that wouldn't load :S

The machine has 3x GTX 580s in Tri SLI. When looking in NVIDIA control panel it states that one of the cards is in a low performance slot.
If I use GPU-Z, 2 of the 580's bus interface is 8x one is 16x.

Just ran 3dMark11 benchmark on Extreme, only got 3k score!

Is it possible for someone to let me know what settings etc I need to alter in the BIOS to get the GPU performance back to how it was?

Sorry to be a fool!

The latest Nvidia drivers will report that message it is nothing to worry about, once you have applied the Overclock and enabled Sli you should get better benchmark scores

Hi Ben,

Many thanks, really appreciate your prompt response.
Going to set them now

Just out of interest, is 1.45v definitely okay for the CPU voltage. I was under the impression that 1.4v was the "absolute maximum" for the 980x according to Intel specs.

Cheers =)

Also, have now re-run 3dMark11 Extreme test after changing the settings and configuring SLI.
Score has gone from around X3000 to X5793, see here: http://3dmark.com/3dm11/1604926;jses...XCC5BwnAALYX8f

This is good for 3 GTX 580s?
