I have an issue with the sapphire HD 7950 vapor-x. It has what is called an "ez boost" button which essential OC the gpu by 100 mhz. When I activated it GPUZ reports it should be at 950 mhz but still only tops out at 850 mhz (yes while using a 3D program).
So I was advised by sapphire tech to go into CCC and mess with the overdrive options. I ended up using CCC to push it up to 950mhz which worked fine but here is where things start getting funny.
When it is running at 850 mhz it is constant and stable (500 mhz when idle). When I pushed it to 950 mhz it likes to jump between 950 and 850 mhz like it is unstable. The tech I was emailing said this is normal but to me that seems very abnormal especially for a card which has a supposeable "bios" setting for 950 mhz to be this unstable.
Any thoughts or suggestions? I've had this card little over a month now and am thinking maybe I should try RMA it due to it not running at what is specified.
