[SOLVED] Nvidia 670 SLI mode not working

[HarpSeal1]

Hello everyone,

 

I've just assembled a new test workstation with dual Nvidia 670s in SLI mode, it doesn't appear unigine is detecting the 2nd 670. I am running the latest driver (301.34), full screen mode is on, 2012-4-11 unigine build, and SLI mode is enabled in the Nividia control panel.

Is there anything I should check? Thanks!

Ok I'm an idiot, I played with it again today and found out you have to manually add the Unigine SLI profile to load when you start the unigine exe. In case anyone else has trouble do this:

download the nvidia inspector tool

 

nvidia inspector -> profiles ->unigine engine -> add app to current profile -> navigate to and select main_x64.exe (or whatever exe you use to start unigine)

 

BTW, SLI scales very nicely in unigine.

Good to hear that :)
