AMD 7770 Freezing when changing settings

Last response: in Overclocking

I recently got a computer with an MSI 7770 I love it it plays bf3 on high settings with low 40 high 55 FPS
I thought I would try the amd Catalyst to try and up the performance to try and get some extra fps but whenevener i change the settings like clock settings or memory clock settings it always freezes the computer and I have to set it back to default.

Is there some ratio of GPU Clock settings/memory clock settings you need?

Hi,

It sounds like the overclock you used was unstable. Try a small bump in core clock speed like 20Mhz and then test for stability by playing your game, if it's stable and the temps are good (<85c) then continue overclocking by increasing the clock speed by another 20Mhz ETC...
