I have been getting low fps in alot of games so I decided to check it out and do some testing. I ran msi kombustor while monitoring my gpu to find out that my core clock speed is constantly changing from 925-850-500mhz resulting in low fps. I've tried changing power control to 20, but still get these fluctuations. I can not return it. Any help would be appreciated.

At these temps the card should not be throttling. But because you are saying it is dropping to 500MHz this sounds like when you were looking at the frequency, the card was dropping into the 2D clock rates. When checking the frequency, wither have the program in windowed mode so you can see both the stress program and the monitor OR use a dual monitor setup but have the stress program as the active window.

Have you checked it before to see if it was changing that much? The boost feature added by AMD on the HD 7950 basically works like that. Its rarely at 925 Mhz for long before dropping down to a lower power state to stay within the specified TDP of the card. It shouldn't go down to 500 Mhz while in 3D mode though.

Personally, I don't like it. I flashed my HIS IceQ HD 7950 to the original 800 Mhz BIOS and just overclocked it myself to a set speed. For me it was just an easier and more sure way to get better performance. As the others have said, if its dropping to 500 Mhz most likely something is overheating and causing it to throttle.

I have pretty decent case air flow(CM storm stryker case). I was going to re-paste the card with some Mx-4, but the heatsink felt as if it was glued down even after I heated it up abit with a blow dryer. Is it a temp issue? Because I have read online of others having similar issues with the 7950 boost.
