Are "Core" Temperature And "CPU" Temperature The Same?

[Gary Brown]

Hi,

Are the core temperatures listed by the manufacturer's specifications
(AMD) the same as CPU temperatures listed by the various monitoring
utilities, eg, Everest and ASUS Probe?

Thanks,
Gary

AMD lists a "TCaseMax" as the maximum operating case temperature.
That is not measured by a silicon thermal diode based
temperature method. Thus, you cannot compare TcaseMax
versus Asus Probe measured temperature. It wouldn't be
technically correct.

For reference

AMD NPT Family 0Fh Desktop Processor Power and Thermal Data Sheet

"Tcase max is the maximum case temperature specification which is a
physical value in degrees Celsius. Tcase max can be any valid Tcase max
value in the range specified for the corresponding OPN.

Tcontrol max (maximum control temperature) is a non-physical temperature
on an arbitrary scale that can be used for system thermal management
policies. Refer to the BIOS and Kernel Developer’s Guide for AMD NPT
Family 0Fh Processors, order #32559."

Typical values listed for an X2 dual core in that doc:

TcaseMax 55C to 72C [i.e. from 0% CPU to 100% CPU]
TcontrolMax 70C

There is a nice section on page 40 of this document, relating Tcase and Tcontrol.
This document also discusses PROCHOT and THERMTRIP, which cause throttling and
computer shutdown, respectively. Throttling can be detected by software programs
such as RMclock.

You cant rely on third party utils to properly monitor your CPU temps.
One can only use them as a guide.

very good, and you can't rely on physically monitoring it, because all
the methods have issues. So what do you suggest to 'properly monitor'
the CPU temp?

oh yeah, the website where the prat that runs it didn't and wouldn't
put a win xp formatted disk on there. (would be useful for a win xp 3
file boot disk)

are you him or are you just a fan?
