Something wrong with my SLI

[mrw1986]

SLI is broken. Here are some recent 3DMark06 scores:

SLI Disabled
------------
SM2.0: 5247
HDR/SM3.0: 5209
CPU: 2428
Total: 11142

SLI Enabled
------------
SM2.0: 2901
HDR/SM3.0: 3999
CPU: 2436
Total: 8118

Been asking about this over at TPU. Here's my original post:

Hey guys,

I'm only getting 13247 in 3DMark06 which seems low for these cards in SLI. I know my CPU might be bottlenecking, but thats why I have it overclocked to 3.15ghz. I'm running the latest drivers for everything and SLI is operational according to ntune. Anyone know what could be wrong?

Thanks,

I have AFR1 selected in ntune and I have tried AFR2 and split-frame rendering. I also have all the recommended settings, all the hotfixes and such. My last resort is to uninstall the drivers, delete the c:\nvidia folder, reboot, install new drivers, reboot, shut down, install the 2nd card/bridge, boot, and enable sli.

Sounds like you need a fresh driver load.

Stop playing with the SLI profiles, btw. Leave them alone.

I just used my method and it yielded me about 11.1k with SLI-Disabled and 12756 with SLI-Enabled. I wonder if its my CPU holding me back now? I have a quad on the way so I guess I'll see!

Default 1280x1024 3DMark tests don't scale with better graphics performance. Crank that sumbitch up to your max resolution with AA and AF then test your SLI scaling.

Or better yet; play some games.

I tried cranking it up to my max rez (1680x1050) and it performed pretty poor in 3DMark06. However I play Crysis at 1680x1050 all settings Very High in DX10 and my FPS never drops below 25...I'm just hoping that 3DMark06 is bugged...

3dmark06 is more like a diagnostic tool to just see what your ballpark score is going to be based on certain hardware that you have.
