7950 Overclocking problems

post #1 of 4
Thread Starter 
I used to have my 7950 running just fine at 1100/1400 on stock volts. Now whenever I overclock the card, whether through CCC or MSI Afterburner, my clock speed wont change from the idle speed of 500mhz. If I don't have any overclock applied the card will jump up to its stock 850mhz speed just fine. It seems like something on my PC is stopping it form going into high performance mode but only when its overclocked. I have tried using Atiman uninstaller and I have tried 12.8 12.10 and 12.11b drivers but still have the same problem. This one really has me stumped. Any help would be greatly appreciated.

check with 12.11 beta 8 drivers and 12.10 cap 1. first try to overclock using AMD CCC. max out power option to +20%. and overclock to 1 Ghz. that should be possible. don't try afterburner or trixx. if you are not able to do stock voltage overclocking then there is an AMD rep . shoot him a query and get him to help you.

Mine does something similar if I have Afterburner running but I don't have Enable Graphics Overdrive selected in CCC. Not sure if that is helpful.
