good max o/c for a 4850 w/zf1000

AlienIsGOD · Nov 27, 2009, 04:44 PM

i am wondering the o/c limits of the 4850 are? I've gotten mine to 765mhz at 54 degrees so far....anyone else out there with a 4850 and comparable cooling? what area your results

750 was max stable for me, unless I put in more voltage, as I have the Gigabyte models that are pre/oc at 700 and have voltage control.

Not much to gain over 750 if at all, these cards need more memory bandwidth at that speed, so your better off going for max stable memory speed if you can hold 765mhz on the core already.

I got around 750 max on my HD 4850 IcQ4.
The memory just hates to be OCed, it artifacts around 1185 or something.
