5850, still rockin on.

For those interested in overclocking the 5850 here are a few notes with a little bit of testing. I've only tested my card. It is listed in my sig.

My highest stable overclock is 849 Core Clock / 1125 Memory Clock. I was able to run at 885 Core clock but after 2 hours of gameplay it would freeze. Any adjustment in memory clock would cause my game to freeze almost instantly.

I have not been able to raise my voltage on this card. No program I know will allow me to do it due to different reasons.

The programs I know that could do this are:

Asus Smart Doctor (Cannot get this program to run. I've tried multiple versions and a few other things.)

Asus Tweak GPU (I can only get the 2.0.8 version to run but it crashes with any adjustment.)

MSI Afterburner (Runs great but I cannot get the voltage option to work. I believe this is due to my card. I *think* it's a non reference and Afterburner cannot adjust the volts on it.)

If anyone can recommend a program to raise my voltage I would appreciate it. I do not want to flash my card bios.

Used to have a 5850 and none of those programs raised voltage for me either, I used saphire trixx and it worked like a charm. Try it out.

Some custom 5850 had no digital control VRMs and thus cannot be overvolted. Sad-panda.

Pencil mod to use a pencil and draw on the circuit board to raise voltage manually.
