I have a 9150 1.8Ghz stock. I have a pretty good mother board but some cheap nanya memory, pretty crappy power supply, and a $8.99 heat sink. I currently have the thing running at 2403Mhz. Temps are 41- 43 degrees. This just seems very odd to me. I couldn't get my AMD64 3800+ to go anywhere near that with better everything.
