Overclocking a 7950 Boost

I am having a problem overclocking my 7950. I know it has boost so the clock changes from 850 to 925 depending on if it needs the boost or not. The problem is that whatever I change the clock to just acts as the boost and not the standard clock. So if I set the clock to 1000, it goes back and forth between 850 and 1000.

Does anyone know what the deal is here? I have tried both BIOS settings. I am using CCC. I also tried Afterburner with no luck. I tried with power settings maxed and at default.

Other hardware:
- 3570k
- ASRock Extreme 4
- 8GB 1600 ram

You could try changing the bios. A lot come with 2 now.

It should change based on load, higher clocks mean more power used, unnecessary with a light load. Set up an on screen display and monitor load in relation to core clock.

Have you tried reinstalling drivers? Check the settings to see if you can force a constant clock. Are you getting consistent framerates, or is it fluctuating with the clock changes on the card?

I understand that. When at idle I think it runs at like 300. This is happening at load (benchmarks and gaming). How do i set up s display like that?

I haven't tried reinstalling the drivers. I could give that a shot. I am getting consistent framerates, and at the end of the day performance seems to be fine. It's just kind of annoying.

If its just going between 850 and 1000 when gaming then nothing is wrong. But download and install MSI Afterburner, go to settings>monitoring>enable OSD and choose core clock as a monitored stat.

Ok cool thanks for the help. This is great though I used to run GPU-Z and FRAPS but this is awesome! Afterburner is the best.

This OC edition is troublesome but once figured out it gives 10-15% performance jump.

I had the same problem now it runs fine @ 1000 Mhz u can increase the power settings by downloading trixx pls connect for details

Its easy in trixx push the power board slider to +20% it will increase the TDP of the card and will stop the throttling as the card will not be hungry to save power.....
