Temps are excellent with maximum core 37C with Core Temp. I had already spent a lot of time trying to keep my temperatures under control since I planned to overclock this system. I can confirm that heat is no problem also because the HS feels relatively cool to the touch even when loaded. Has anyone tested this software with an 8 core system and FBDIMMS? I tried upping the voltage from default 1.8V to 2.0V but that didn't seem to help. I have 4 sticks of Mushkin DDR2 800Mhz which is supposed to be rock stable. I can run this machine with all other software and benchmark programs at 4.2Ghz with no problem. So I am surprised that it cannot run the benchmark at default 3.2Ghz.
