So is it possible to overclock a 5850 in linux more than 775Mhz without modifying the BIOS?
btw why can it be done in windows and not in linux?
Hi, with AMDOverDriveCtrl you can go up to 900, beyond that I think you need to edit Bios.
http://sourceforge.net/projects/amdovdrvctrl/AFAIK windows has a tool, trix or something, where you can overvolt and stuff, thats something
missing for linux.
It depends on the card manufacturer. I had a Asus 5870 that allowed me to go to 1200Mhz core speed without wihout flahsing (in reality I could not go over 1010 without the card becoming unstable). And then I had a XFX 5870 that only allowed me to go to 900Mhz core speed, and had to flash it.
