Can no longer overclock 2900XT manually
 

Hi Guys, I just upgraded my video card driver from 8.9 to 8.12 for my 2900XT. I uninstalled in control panel, booted into safe mode, ran DCP and re-booted. Installed drivers and everything runs fine. The only problem I have is no program besides the CCC will allow me to overclock the card. Normally this wouldn't be much of an issue since I can still run my games overclocked using the CCC but when I am folding using the GPU client it will only run at 2D speeds. The gpu client cannot get 2xxx series card to go into 3D speeds (this is a know problem) so owners of 2xxx series cards have always had to use something like Rivatuner or ATItool to manually put the card at 3D speeds while folding. Now I cannot force the card to use 3D speeds while folding and I am taking a points hit. Any ideas?

Rollback the drivers IMO. I don't think any recent Catalyst driver has brought any improvements for the HD2900XT.

That is my only option so far but I wanted to see if anybody had a fix.

Have you upgraded to the new v1.22 core and 6.23 client, there are supposed to be bug fixes and ppd gains. I don't use ATI cards so I'm not sure if it applies to your card...

Yes, I have upgraded but the core but the 2D/3D speed issue is in the hardware, not software (the hardware doesn't recognize folding as a 3D application). I don't think that will ever change.
