I tried using AMD GPU clock tool but to no avail, heres the strange thing though:
- It would show my clock speed as 124Mhz until I reselected my graphics card from the list, then it would show 495Mhz - I can OC it to any value I want, press set clock, but when I read clock info, it shows 124Mhz - If I reselect it in the list yet again, it will show whatever value I set it at - Catalyst Control Center showed me at my default clock (500Mhz) - AMD OverDrive showed my GPU clock speed at whatever value I set it at - GPU-Z showed my clock speed at whatever I set it to, and increased my pixel fill rate by far - WEI showed no improvement, nor did any game In other words, GPU-Z and AMD OverDrive can be decieving.... Now back to the voltage, have you tried AMD OverDrive? Maybe your voltage is locked via OEM or BIOS. As for driver updates, you could always force it. Heres how I do it on my Compaq on XP: 1. Download the latest Catalyst Desktop drivers (10.8 in this case) 2. Install it (you'll notice it won't show ATI Display Driver nor Catalyst Control Center in the list) 3. Manually install your graphics driver via Device Manager (use the inf from the C:\ATI\Support\Driver\W7INF or whatever your OS is folder) 4. Go into C:\ATI\Support\Programs\CCC folder in explorer 5. Install everything in that folder (except utility64 unless your on x64 OS) 6. Reboot (not required, but nice to do anyway after all that) 7. Profit Like I said this works fine on my Compaq 515 on Xp because ATI doesn't have universal Mobility drivers on XP. But since I'm with HP, their mobility package works fine on Windows Vista/7 On Sat, Aug 28, 2010 at 1:56 AM, Gerard <[email protected]> wrote: > Hey guys, Long time =p > Anyway, I'm trying to change my Laptop GPU's voltage using AMD's GPU > clock tool.
