I recently purchased a Phenom II X6 1055T and it appears the temp diode is calibrated incorrectly. My ASUS Probe is showing 56C under max load while CoreTemp is only showing 46C. There is an article about this on Xbit:
As for the thermal mode of our overclocked processor, it seems to remain quite acceptable. But unfortunately, we can’t claim that with all certainty, because the thermal diode in the first batch of Phenom II X6 processors appeared to be improperly calibrated. As a result, processors were reporting obviously lower temperatures. For example, as you can see on the screenshot, the CPU reported its core temperature to be no higher than 55°C (gray graph), while the mainboard diode beneath the CPU socket (yellow graph) read the CPU temp as 65°C.
I am currently using the stock cooler and the CPU is at 1.33V under load. My question is, how hot should I let the ASUS Probe temp get before I start worrying? According to AMD the core temp of the X6 should not exceed 62C.
I am planning on upgrading to water soon but for now, what is the maximum I should let the ASUS CPU Temp get? Also, is the ASUS CPU Temp higher or lower than the actual core temp? On my previous ASUS AMD systems the ASUS temp and CoreTemp have always been close but ASUS was always higher indicating this is a conservative temperature. Is true? Thanks for all of your help.
