Overdriving Overdrive

[nikost4]

Hi, currently I'm using RivaTuner206 to overclock my GPU but it doesn’t seem to vary the clock speed depending on load as overdrive dose. So I would like to know if there is a way to allow overdrive to clock my GPU and RAM higher than it currently dose. I've got a 3850 on Vista 64 if that makes any diferance.

Welcome to XtremeSystems,:welcome: This site has modded bios files for 3850 and 3870. the 3850 one will allow ccc to clock as high as 900 but suffers from a bios lock limiting the cards actual speed maximum to 864. I have used it and it works perfectly.

So the bios in your link actually turn up the CCC limits? Are they for a specific 3850 or can I flash any card with them? I'm running a Sapphire 3850/512.

no you need to read the thread for 512 cards also in the bios section. i think there are a few that unlock as well.

ATi Tray Tools allows access to Overdrive with extended limits.
