Why guiminer is using different amount of GPU each time I restart my copmuter?

Why guiminer is using different amount of GPU each time I restart my computer? I'm running guiminer-20121203, NVIDIA GeForce GTX 670M, poclbm.exe with flags -s 0.005 -f 60 What I noticed was, it was 35Mgash/s with 75% GPU usage. And after I restart my computer, it became 50Mgash/s with 100% GPU usage with the same flag settings.

Also, before when I tried only with flag -s 0.010 it utilized 100% GPU, but without restarting computer, using flag -s 0.011 reduced GPU usage to 60%.

What's going on??

Other applications can alter your GPU settings not just guiminer.

If you take a read over this question here it may reflect a similar circumstance which is causing a variable hash rate on your hardware. Without knowing your exact usage of your computer though I cant say for sure.

I swear god I tested this, with exactly the same condition. Ok, just to be sure let's test this again... And.. I can't reproduce the situation I described above... Now same flags gives same hash rate and GPU usage. So I guess I was wrong. – Sida Zhou – 2013-04-10T05:38:06.257
