Overclocking SLi

post #1 of 13
Thread Starter 
Hey guys!
I was wondering how you overclock when using SLi do you unlink them, overclock them separately, and go with the lower one, or do you overclock them while still linked? Cause I've had to reinstall the drivers once while trying to oc while still linked.

When overclocking SLI both cards increase at the same clock frequency when linked.

What are you using to overclock. Keep in mind that all cards are not created alike.

Well, I've tried the built in one, Nvidia's overclock tools (Ntune I think) and Atitool.

None of them have worked? What was the issue and why did you need to reinstall drivers?

The built in one doesn't show up when in Sli mode (anymore), Ntune freezes after about 5 seconds and 1/8th of the progress bar, and Atitool made some major artifacts and tried to keep going until it froze also.

The reinstall was due to the built in one showing up once and me trying to do it manually (going up 2mhz each time) and when it rebooted, the display wouldn't show.

2 words:
flash bios
Test them individually and find their respective stable OCs. Then flash those clocks with max fan speed and voila, no software needed.
