Hey guys.... I'm about to get my XFX HD 4890 in a couple of days... I heard many people were able to OC this sucker to 1Ghz. They were using a volt mod....

Where can i get hi mod at?

thanks

The oc knobs are core freq and mem freq. You get a better impact on core-freq adjustment. Read the material.

I got mine to run @ 1GHZ core w/o volt mod.... Try it out.

Good Luck

Personally I am not a fan of volt modding, the gains don't seem to be worth the effort or risk. Quite a few of these cards are coming close to or at 1GHz on air stock anyhow.
