XFX ATI Radeon HD 4850 overlocking?

[philaaay]

So I've been trying to use the Auto-Tune feature in CCC to overclock my 4850s, but doesn't seem to work that well. I was curious if anyone knows what speeds the GPU and memory clock can handle; stock speeds on the GPU is 625 MHz and stock speeds on the memory clock is 993 MHz! Thanks in advance!

I wouldn't really know, but I'm guessing that you should be able to overclock it from %8 - %15 without problems. Try using rivatuner and tell us how it gos

You cant just slide the bar all the way to the maximun, try going into small portions and then test it. I remember when I raised mine at first it wouldn't pass that test at max, but when I went back and did it step by step, then it worked. Try doing that
