overclocking in SLI

post #1 of 6
Thread Starter 
ok, so i officially feel like an idiot.

I finally got my other 8800gt back (let a friend borrow it after he got robbed)

I finally have my system exactly where i want it in terms of clock, except the video cards. I would like to overclock them just a bit. I would be happy with 650 core and perhaps 1750 shaders.

So I install riva tuner 2.08, which is what i thought everyone used, to find out it only will clock a single card. W T F??!

So my question to you guys is this......how do you overclock both cards in sli?

Im not in touch with the latest sli overclocking.

But in the past what you have to do is set your cards to the speed you want indevidually.

That means, boot the computer with 1 card at a time and overclockthem.

Then once you have both cards OC'd .. put them back in together and sli them.

enjoy

In SLI both cards have the same clocks. So when you overclock in riva tuner your are overclocking both cards to the same levels.

then why does the nvidia hardware monitor show two seperate clocks for the cards?

Also why does it show 4 separate listings for my 8800gt's in the program?

Hmm, I don't know about that one. You have SLI mode enabled?

I was curious about this as well. I just set up my 8800GT SLI, and after enabling it, I started poking it til it puked (in rivatuner) in an overclock. I finally got it to 710/1010/1780, but I noticed the same discrepancy in nvidia system monitor i.e. one core clock was OCed, while other was stock. I opened Rivatuner (2.08), set the clocks again, saved it for after boot, and rebooted. Voila! Nvidia system monitor had them both on the same clock. You should be able to poke it too; rivatuner WILL do this for you.
