"Core Temp" - monitor temps on K8s and Core/2 CPUs (updated

Recommended Posts

Well i was searching ITE Smart Guardian. to find out if there's one that reads Duel core temps. ran into core temp tread first. got to first page and seen a new ver out :D so me downloaded it and HEY its not showing tcasemax or TPD so i make a pic showing the two ( Don't try and run two vers at same time :D) trust me lol. So did they get this fixed? And does anyone know if there's a ITE Smart Guardian for Duel core?

There is no doubt that TheCoolest has done some excellent work on the CoreTemp program. Kudos to the man.

But the program may not be 100% accurate with 939 and earlier CPUs.

From the 3rd Post in this thread:


Hello guys.

First of all I want to make something clear:

This feature was unofficial until the RevF AM2 CPUs, so I wouldn't take all readings you get from older chips as granted, as the DTS* could be off or not callibrated properly, I've seen a lot of dual core chips where the temp difference between the cores would be like 12C, and one of them would report sub-ambient temps :D


I think that in the majority of cases it is pretty much accurate, though.


Regarding how it calculates temperature on AMDs, Intel complicated things quite a bit with their chips, AMD kept it pretty straight forward. Just read a value from a register, substruct 49 from that value and you have the temperature in C.

The temperature can range between -49 and 206C, at least in Rev F. I don't know if in earlier chips its the same, but I'm assuming it is.


Another thing I noticed, sometimes, in sub-zero temperatures it'd show much lower temps than what MBM5 and the likes report, I don't know which of the two programs is more accurate, but it is possible that the DTS loses its accuracy when temps get really low.


*DTS = Digital Thermal Sensor.
