Can't disable OCP.

post #1 of 10
Thread Starter 
I'm trying to disable OCP on my GTX 580s, but it doesn't seem to work.
GPU-Z and Furmark can't seem to disable it.

I'm running the latest beta drivers.

Why would you want to? The entire purpose is to prevent them from burning up in Furmark.

I'm trying to find a stable overclock.
Not so easy when the card is being pulled back.

Furmark really isn't a great stability test anyway.

Heaven loops, Crysis/Metro bench loops & 3DMark11 should expose instability much faster... without frying your cards in the process.

The long and short of it is this: Don't disable OCP. It holds your card back when it needs to be held back. Just benchmark with something that doesn't hit it, like a video game. (As the other poster has said).

Personally I use OCCT or OC Scanner.

OCCT is nice for finding stable OC. Just check the error check thing and you can find your max stable OC pretty easy. When the screen isn't swarming with white dots then the OC is probably stable. OCCT usualy shows a few dots even on stock clocks on my GPU but once i go over 650 core on my GTX470 on stock volt and the OCCT screen starts swarming with white dots and that means the OC isn't stable

W1zzard has said that OCP / PDL can't be disabled with the latest drivers.

Same time the 590 became ultra locked down voltage/PDL wise.
