How do you get past the 700mhz limit on HD4850?

post #1 of 4
Thread Starter 
Afterburner, CCC won't let me get past 700mhz for the core clock and ATI Tray tools locks up if I try to set the slider past 700 core.

I have a modded cooler Arctic Cooler with 2 Antec tricools on top, the temps are 32c idle and it won't break 40c under 15 minutes of Furmark Extreme Burn-In.

I was planning on pencil modding the card, but I wanted to make sure that I could break the 700mhx limit before I learned how to do that. Does anyone have any advice for me?

try Radeon BIOS Editor and increase the voltage for every profile. Flash the new BIOS, restart, and try to set 720MHz on core.

Thanks man!

I broke 715 core with ATI Tray Tools, but its not very stable. I think I need to try pencil modding.

pencil mod works well. i had the 4850 core up to 800 mhz stable in certain games. not stable in others.

i didn't have to flash any bios to extend the upper range of clocks. i just used afterburner.
