Need help with graphics card overclocking

post #1 of 4
Thread Starter 
Now, i just overclocked my Radeon 5750 from the deafault at 740MHz core, to 840MHz, and the memory clock, from 1200 - 1335. Now ive been playing some games, and there is no problems. Been playing Shogun 2: Total War, and Mafia 2, and it seems stable. I also ran a Furmark test, with 2x MSAA (anti-aliasing), with 1680 x 1050 resolution (the resolution i normally play games in).
And it only reached 78*C, after running it for 20m 30s, with an AMD stock cooler, and automatic fan speed.

Stable, or unstable? Less or more overclocking?

Help, please? smile.gif

If your running the game and ran a stress test without any artifacts, black screens, video tearing, stuttering, then I'd say that's a good over clock.

What you want to do is bump 15Mhz at a time until you see your game video spots or benchmark fails like 3D Mark 11. Then you went to far and you back down. The temp you posted is fine.

Before running any kind of voltage tweaks I'd find out from someone who owns the card some info first and their over clock attempts.

Well ive been running with this for a day now, and it seems stable. There was no glitches in the games, or the test. It ran with no problems.

And about the temperature: when overclocking, what should the max temp. be? At what temp. will i know that i went to far?
