SLI Overclocking

[josh6079]

I've seen how there are several overclocking utilities out there, some better for SLI others for single, and I was wanting to know some things about them.

I mainly use coolbits right now, when I had one card I used Coolbits and Rivatuner. I also just got nHancer and I imagine that both Riva and nHancer are probably better, but I just don't know to much about their options.

Right now I've got an N515/18 both cooled with NV5R3's, max temps are 70~75 on the lower card while the upper one stays at a nice 67. But I have Coolbits detect optimal settings just to give me an idea of where to start. It puts my GPU at 515 and my Memory at 1.21. But when I start BF2 in game I get crazy artifacting.

Does anyone know if Coolbits clocks both GPU's to the same frequency when you overclock them or if it only does that to one?

The driver has only one setting for core/mem/fan speeds, which are applied to both cards.
I have never seen a tool where I can adjust the two cards separately...anyone?

Okay thanks, I was just wanting to make sure that the frequencies were being applied to both cards.

 

[josh6079]

Oh, sorry and another thing. Out of Coolbits, Rivatuner, and nHancer which utility is probably the best to use?

 

[NoDamage]

Yeah, the slider applies to both cards when you overclock in SLI mode. You can't adjust the speeds independently because they need to be in sync for SLI to work properly.

Thanks, but which program do most people use or which is better?
