I can't get stable

post #1 of 4
Thread Starter 
My oc is 915/1125 i've been upping the core only and at voltage 1,200 it still wasn't stable, i dropped the memory to lower values, such as 500 for an example cuz what i am doing doesnt require the memory clock to be high.

I've had so many lockups and had to reboot over 10 times already, and i know if it keeps up, maybe next time it won't boot. And if i up the voltage more, the VRMs get near they're max temps so i lowered it at 1,187(not like it helps it get stable)

I only ask...why?

Ninja edit:
If it matters i also once left it at 850/500 at 1,174 and it still locked up

I assume it doesn't lock up @ stock speeds, right?

For reference, my HD 6870 can't do 1ghz core, unless I up the voltage to 1.268v.

These cards (including yours) can happily take up to 1.3v with not risk whatsoever.

1.3v is the max for air cooling, so you're good.
