9800 GT + 8800 GT SLi Problems - Page 4

post #31 of 40
If you want to run the second card for PhysX, get rid of the SLI bridge you installed trying to run SLI!!! Then your system will recognize the second card as PhysX.

For reals.

So Crimson ... how about some benchies with single vs. SLI? How's the SLI scaling looking?

I used to have an XFX 8800GT with a PNY 9800GT. They didn't work in SLI. You are lucky.

Some Benchies for you:

Using the Heaven benchmark in DX 10 mode, Shaders high, anisotrophy 1, anti-aliasing off:
SLi Disabled + stock speeds: 392
SLi mode + stock speeds: 592 (33% speed increase)
SLi mode + overclocking: 663 (40% speed increase)
(overclocking was core clock 600 MHz to 740 MHz, and memory 900 MHz to 960 MHz)

Useing 3D Mark Vanage Demo at default settings:
SLi Disabled + stock speeds: 4,849 marks
SLi + stock speeds: 7,417 marks (34% speed increase)

I think my 8800GT is running in a PCI-E 1.0 slot. I suspect this is bottle-necking my SLi performance.

I wonder if flashing the BIOS on my 8800GT might give me a tad more SLi performance. But, regardless, SLi is clearly working.

Also, I am sorry for raging at everyone. *hugs* We all friends now?

Gonna play around with the settings and see if can squeeze some more performance out of my weird SLi setup.

Nvidia has done a lot to improve the SLi drivers. ^__^
