6950 not performing

post #1 of 16
Thread Starter 
Hey guys, I ran Unigine heaven with my 2gb HIS 6950 today and am getting weird results.

For my score I got 950 pts, and upping the core clock from 800 Mhz to 1000 Mhz with a voltage bump to 1.2v yields not a single extra fps?

Whats wrong?

CPU limited maybe? Try changing the CPU clock speed while keeping the 6950 at constant speed and see what happens.

Actually...

I've noticed the same thing as this: From stock cpu/gpu(3.2GHz & 800MHz) to OC (3.6GHZ, 2.6GHz NB & 900/1400 gpu) I've not noticed any increase in performance with heaven benchmark either, bit wierd indeed. Well negligible difference anyway ~1050@ stock, and the same @ OC, this is at 1080p, 16AF and normal Tess.

Score: 45.5fps

Smells like driver issues.

Yeah, it works well with games, but it stutters allot of the time... jumping from 50fps to around 20 for a couple seconds.

Whats interesting is i've never seen the card break 60 fps in any game, even though no vsync options are on...

Have you checked whether or not your card actually runs at the correct core and memory clocks while on load? You can do so with Afterburner.

Any videos playing in the background that might have hardware acceleration enabled? Stuff like YouTube?
