Ok, so I'm a noob with the whole SLI. I just got my computer last week and am having an issue with it already. Game freezing up.

The more I read the more I see there is to SLI. One, the mode.

You have AFR 1 AFR2, some other thing. etc.

Currently in the Nvidia control panel I have it enabled, but set to single GPU.

Does this mean I'm not taking advantage of SLI in gaming? Do I need to switch to AFR or AFR1 in order for SLI to work?

Maybe I should just stick with one card....
 
Single GPU means you're not using SLI in that game. Your best bet is to NOT CHANGE the SLI mode because the drivers have custom SLI settings for most popular games.
 
That's a little confusing. So I'm not taking advantage of the game in single GPU, but you're saying not to change it.

So, what do I do to take advantage other than leave it in single GPU?
 
If the profile for that game DEFAULTED to Single GPU, then you're probably best off with Single GPU in that game. The best advice is to not go screwing around with your SLI profiles. They come with the driver optimized for most games. But by all means, if you think you know more than nVidia about which SLI rendering method to use for which game then go for it.
 
there is also a bug in the newest nvidia drivers, they may say(in the games profiles section of the cp) that they have defaulted to single gpu when in fact they are using the custom sli setting, go to sli forums to read about it.

I don't know, I've gotten a few things to run a bit faster by switching from AFR-1 to AFR-2 in some profiles.

However, in the case of the OP, I think he means in the global area, not the game profiles.

Correct, the global area. Haven't even messed with the game profiles.
 
The game profiles override the global settings. For ex: If you look at the SLI mode for Crysis in the latest beta drivers (169.21) you'll see that it says Custom there. Nvidia's custom SLI mode is a modified AFR technique which means that when you launch Crysis, it uses that specific game profile and not the global one. The only time the global profile is uses is:
1) When there is no game profile for the specific game you are playing
2) When the setting for a specific game is set to "Use global Settings"

Hope this helps,

Much appreciated Aux. So I'm playing Timeshift, so I should go to the game profiles and see if it's there and check to see what's selected.

I think I'm running 169.03? (i'm at work), so depending on if that driver even has Timeshift in it, could make the difference.

I'm wondering if me keeping the global setting to single GPU while playing a game might be the reason for my freezes in game.
