An Understanding of Temperature on AMD CPUs and APUs

Post by johnwalker » Wed Mar 29, 2017 10:45 am

Hello,
Does HWMonitor say your CPU/APU temp is 70C when idling but your CPU socket feels cool to the touch? Is Core Temp only reading 10C but it's not possible because your room is 28C? The reason is that these and other 3rd party programs are not interpreting the AMD TCTL signal correctly, although they seem to work fine for Intel CPUs.It is perfectly safe to operate in the full envelope of thermal margin. When thermal margin runs out, your CPU/APU will throttle to a lower power state until back in the thermal margin. It's easy to test this function to verify that the thermal trip does indeed work according to the calculation.AMD. Further information can be found in the BIOS and Kernal Developer's Guide This temperature is based off of precise calculations that are very accurate during heavy loads. This is what you should be concerned with while stress testing your CPU. This is also the signal that is most often erroneously interpretted by 3rd party programs like.

Thanks,

I didn't find the right solution from the internet.
