Hi lads, I just bought my new graphic card 7900GTX 512DDR3 and put in to my Dell E1705. Unfortunaly, I can't change any clock for GPU and MEMORY, why?
I found a topic with list of bios, which is locked and unlocked:http://home.tele2.es/jlgm/peng.html
How find version of my bios in my 7900GTX?
I used nvflash to copy this bios and I opened in NiBiTor2.8a.
I can change a clock for the 3D operation and voltage but which setting will be safe? I can't try to find safety setting because I can't oveclock my 7900GTX
Power supply is: PA-15 150 Watt
UPDATE: I reflash bios from basics version to 790GTXUO version from first page and I can't change clock for GPU and MEMORY still
NEXT UPDATE: I just turn off the clock test in RivaTuner 2.8 and now I can OC.
GPU: 500MHz to 626MHz
MEMORY: after 600MHZ - artifact, very strange
3dmark2005 after OC: 9479, NICE
