2 285's same benchmarks and win scores

well is SLI enabled software wise?

yup, along with the enhancement patch. the newest beta drivers. I am thinking it is a mobo problem

What are you using for your benchmarking?

3dmark 06

Is SLI enabled in the BIOS also?

im not seeing anywhere in the bios to enable it or in the manual

everest ultimate will show if sli is enabled
* I have (2) 285/sli also asus X58

It is showing both cards with SLI enabled. One at 16x and one at 8x. How do I get them both to 16x??

oke, go back to 190.38

Yah, thought of that....thanks though. It reads one as 16x and one as 8x no matter where I put it.

If you're switching back and forth between sli on and off you know you should reboot each time, right?

Also, with 'stock' settings (no AA, 1280x1024) Canyon Flight is the only test on 06 that's going to be significantly faster with SLI-enabled. They all should be a bit faster (except the cpu tests of course) with SLI, but Canyon Flight is the only one that really scales well at all. The resolution on '06 is so low that the other tests are pretty well cpu-bottlenecked when running SLI 285's.

Try benching with Vantage (preferably on High or Extreme) or Crysis or one of the Stalker benchmarks (Clear Sky or Call of Pripyat) using some tougher graphics settings (Very High, some AA, 1080p or above res) and you'll see a much bigger difference w/multi-gpu.

Ok, so here is something interested too. When I go to nvidia control panel and click on "performance" I get a BSOD saying nvoc64.sys and a mem dump. It happens every time. Maybe I should wipe out all the nvidia drivers and reboot, then reload my drivers?

I made that change to 16x/1x and it got to 52-54fps on the crysis benchmark at 1920x1080 maxed out, 4x AA, all the filtering turned on. I would guess that I am ok then? That is about all there is to get? Everest still thinks the second car is running at 8x but I doubt it is with the 10-12fps improvement I got from making the change
