Question GTX680 SLi one card will go idle during testing

Hi Jason!

Hmm it's weird since your result for 2xSLI on OC'ed 680 seems to be quite right. We read that the cards were both OC'ed chip to 1200 MHz and memory to around 1650 MHz.

Could you try to rename ALLBenchmark exe to afr-friendlyd3d.exe? Please write me if this have affected your score and your clock readings.

Cheers!

I was over at guru3d and posted the same topic and someone said to set AFR 2 in NCP to get SLi working. I never posted the scores that I got when SLI was not working.Thanks for the reply!

I also got a second GTX 680 and my second 680 is going to idle shortly after launch, I did try the rename the EXE and that did not change anything

you can see above that one card is going to idle during testing that cap is from about 30 seconds in

You have to go to Nvidia Control Panel and select AFR 2 for the SLI settings. (Alternate Frame Rendering 2)

Thanks i though i had tried that but this time it scaled quite well got 9395. on the final version will we have to do this or will it be fixed?

Hi Joshua ,
So now time for the truth! We can't fix that unless nvidia will fix that.
In other words, nvidia recommended settings works like this:
1. check the filename
2. find the setting for filename - hmm for catzilla it would be afr2
3. change internally to afr2
works! .
So, when nvidia will get their driver hands on catzilla, then it will work.
Currently we struggle with 4 cards since they won't scale unless you will rename the file to: AFR-friendlyd3d.exe . Go ahead - you may get some extra points with this, because AFR-friendlyd3d.exe is extra optimized setup without any sync on GPUs

Thanks!
