They are?? I used three programs: Coretemp, HWmonitor and HWInfo and all three reported the same temps.
I just ran Prime95 overnight for 7 hours and 48 minutes. 0 errors and 0 warnings. I had the CPU OC'd at 3.9GHz.
Edit; Well in HWMonitor TMPIN0 shows 42c idle and TMPIN1 shows 38c. I heard that AMD CPU's usually are about 5 through at most 20c off from their real temps. TMPIN0 is my socket temp so I'd guess my temps were

36c? Highest the CPU temps showed was 41 so I'd still say those temps are fine as they'd still be below at least 65c while under full load...
Yea that's what I did at first. The CPU Vcore by default was 1.284. I manually set it to 1.320 and then tried Prime 95. 7 hours and 48 minutes no errors. Highest temps was 41C. I didn't touch the RAM though.
