To anyone who thinks their clocks are rock-stable. Try running the crysis demo gpu benchmark a couple of times. I have a slight feeling that some of you will be a bit dissapointing...with the red textures appearing all across the screen suddenly :P. Even tho' my shader clock was ati-tool hairball stable, it was nowhere near stable with the crysis gpu benchmark. My whole screen froze and was filled with small red squares at some point in the loop.

So by all means, if you want to REALLY check your clocks, go grab the crysis demo and run the gpu benchmark.
