6950 core clock stuck

I have a 6950 flashed w/ 6970 bios. Recently I noticed the core clock was stuck at 500 mhz even though it was set around 900. If I checked the "Reduce DVI frequency on high-resolution displays" inside CCC, restarted and then unchecked it, everything went back to normal. (Work around I found researching the issue)

However I noticed that sometimes when I would start to play a game, I would have MSI afterburner up on the second screen so I could monitor the clock. Everything would start off all fine and dandy and then about an hour or two into playing I would notice it was stuck at 500 mhz again...

So I was like, this is ridiculious, updated catalysis control center & MSI afterburner and now the clock won't go above 725 and after the CCC reinstall, the max settings are now back down to what a normal 6950 shows. aka 840 mhz etc.

I'm starting to run out of ideas.

Edit: There was a setting limiting the clock to 725 although the max reflects what a normal 6950 can go, even though I've flashed it.

Edit2: Disregard that, it only momentarily went above 725

got somewhat similiar problem... my 6950 wont go over 725 core clock.. dont understand whats the problem is. Everything is stock.
 
Specs for both of your rigs please.

Questions;

What version of Afterburner are you using and what drivers?
Is your settings locked in on Afterburner? also, Have you tried clicking reset on msi afterburner?

What bios did you guys flash to your cards? Did you guys make them in RBE or did you download them from somewhere.

Have you guys checked amd overdrive to see what the clocks there are set to and also did you try adding +20 to powertune settings?
 
i dont have msi.. got his.. havent installed any his software only amd 11.10 catalyst

its a standard 6950, havent touched the bios.. says 800/1250 in GPUz.. however as i said when i play game or test kombustor GPU core clock only goes to 725
