I would trust coretemp as BIOS reads from the socket and not the cores
post #3 of 10
I've researched this over and over again, and the final consensus by mainstream OCN is to follow the highest temperature of the two. Realize that coretemps are not actually measured. They're estimated mathematically. The socket temp is physically measured (which can be more accurate or way off depending on the condition of the thermocouple). AMD also rates their max CPU temperature based on socket temperature.

In my case, my socket temp was showing 10-15C higher than my core temps, so I base all of my overclock on that.

How do you measure your temp under load if you use the bios temp?

I use CPU-ID's HWMonitor software. It's free and reads out a ton of useful system parameters.

Bios is higher becuase in actual fact the cpu is not on idle, therefore you get substantial increase in temps. When you boot into your os use either realtemp or coretemp to read the idle temp.

I had always suspected that.... Makes sense. I assume Cool n Quiet and all that isn't active during BIOS....
