Well, I just tried manually entering 1.164 volts in the BIOS for the CPU core voltage and ran Prime95 again. This time, the maximum temp was about 70 degrees at 4.4 GHz. When I run CPUID's HWMonitor, it has an entry for IA at 1.194 volts. Previously, when the CPU core voltage was at 1.164 under BIOS 0501, HWMonitor had an entry that said IA "Offset" at zero volts. Should I be concerned about this? I didn't change any offset in the BIOS. I just manually entered the core voltage. The CPU is throttling correctly in terms of clock speed under no load, but the core voltage seems stuck at 1.164 where previously it would lower under no load.
