the highest i have hadthis is 2250,temps run between 38 and 54c depending on all the settings.I have a good heat sink and am using artic silver3.Have used MBM and bios and they are very close.But that was my guess that temps are just to high some where.will not restart after about 2125.but starts to freeze around 2185. I know it can do better, just cant figure it out.how hot is to hot for this cpu.what was the best fsb x cpu you had.
