I mounted a Accelero S1 Rev2 on my Sapphire HD 4850 with a 120mm 500RPM fan on it.
Idle temps are 50° and load temps are 70°-80°.
Somehow I can't get higher than 650MHz. Memory clock is at 1100Mhz. Everything beyond 650 core clock results in artifacts.
Why are you guys are all able to get that much better overclocking results?
Oh and what is temperatur #2 and #3 in GPU-Z?
