Hey
I have a HIS Radeon HD4850 Turbo IceQ graphics card (CCC v9.11) which is overclocked at the factory by HIS. However, the clock speeds it came with are very unstable and I have been trying to get a stable clock speed for some time now. I was getting a lot of display driver crashes and I noticed that this occured less when I played around with clock speeds but I havn't managed to get rid of it all together
Possibly the biggest problem with this is that CCC limits the GPU clock at a 500 - 700 Mhz and the memory clock at 1100 to 1200 Mhz. I read (at the link below) a good stable clock speed for this card is 700/1050 but am unable to test this out. I did notice that the link I provided shows CCC allowing users to go below 1100 Mhz.
So I was wondering, is there any software I can use to properly overclock this card, or is there any way to derestrict CCC?
I should note that I've tried RivaTuner (doesn't support this card) and ATI Tray Tools (which clashes with my anti-virus).
Any help would be great
