What's More Accurate - Temp

[Mista Fadedglory]

If I use ASUS Probe itsays that my CPU Temp is 48C. If i just look in the
BIOS it says 60. which is generally more accurate.

and is there smething better than ASUS probe?

 

[JAD]

there were some ASUS boards that had inaccurate bios temp readings. An update of the bios fixed it.

If you are using WinXP, 2000, or NT both are correct. XP/2000/NT uses cpu
'throttling' that results in approx. 10degC difference (lower) than what is
seen before the OS loads. If you are using Win98 or some other OS, then you
have a discrepancy.

So then is 60C ok for a BIOS CPU temp reading?

I guess that depends on your hardware. That does seem a bit high for idle
temp.

I found with my Asus P4PE the CPU temp rises to a higher level the
longer I'm in the Bios. It's low when I first enter the Bios, but
rises to a higher then normal temp (can't remember temps, but it was
nothing to worry about). Once I booted into WinXP the temp would drop
back to a normal level.
I wonder if the CPU usage rises to 100% while in the Bios? That would
explain the higher temps.
Programs better that Probe:
SpeedFan, monitors temps and allows you to control fan speeds, if
your motherboard monitors fans too.

Motherboard Monitor is also a good monitoring program, but give no
fan control.

You must remember that when viewing the bios there is no idle routines like
in WinXP so the cpu is running close to flat-out

 

[Stronium]

I could've sworn that I already clarified that XP uses throttling...

My reference was to his temperature. 60degC seems high, regardless of the
prescence of throttling or none.

if your MoBo really measures temp from CPU on die diode, the second is
kinda correct ...

"Gandolf_One" probably ignored your "clarification" because he thought
that throttling has nothing to do with idling. Isn't throttling used
only when the CPU gets too hot, while idling is used when the CPU has
nothing to do? Please clairify that.

And how do you idle? Win95 used a "HERE: JMP HERE" type routine.

Win2K and above uses "HALT" to idle ... which is one way of
throttling.

OK, Ralph, I'll take your word for it, but I don't see how it has
anything to do with whether the OP's XP uses throttling to lower the
temperature while the OP is observing the temperature in ASUS Probe.
And you didn't answer my yes or no question. After some googling, I
can now answer it myself: No, "throttling" does not just refer to
slowing the CPU when it gets hot; it can also refer to slowing the CPU
to save power. It seems to refer most often to one particular method
of slowing the CPU, rapidly switching between full speed and idle or
something similar. Some Intel CPUs do it automatically when the CPU
gets too hot. It can also be done under software control on most
CPUs. They say that running cooler and saving power are not
necessarily accomplished with the same method. Throttling is often
done without actually entering the low-power idle mode, but just
suspending some CPU cycling to reduce power.

But "throttling" never refers (from what I've seen so far) to stopping
the CPU altogether for "long" periods of time, such as is done (using
the CPU's "idle" function) by most OSes when there's nothing to do.

So I still think that it was "idling", and not "throttling", that was
the proper explanation of the lower temps (if either of them is).
Yeah for "Gandolf_One".

So your whole participation, in this thread, was to argue about semantics?

Hmmm .. Well, it stops the processor. Doesn't slow the clock down,
just STOPS it.

" ... but just suspending some CPU cycling .. " BINGO!

"long" periods. Define "long".

No, it was to defend the guy that you flamed because he apparently
didn't understand that you were talking about idling when you talked
about throttling. (Or that the OP should have been told about idling
in addition to throttling.) Whether you were right or wrong in your
use of the word. The idea was to encourage you think twice before
flaming people.

I also wanted to know if you were right or wrong, but got no help
from you or others, so I googled for it, and reported my findings.

 

[Gary W. Swearingen]

Howdy!

I didn't say it slows the clock. (Though some kinds of throttling on
some CPUs does slow the clock.) And I didn't disagree with anything
you said, and as you obvserved below I said that the clock can be
stopped during throttling. You're arguing the wrong issue.

" ... but just suspending some CPU cycling .. " BINGO!

That is what I said.

No, you said (maybe accurately, but irrelevantly):

I had just read an Intel doc that said that their throttling suspended
some CPU cycling (eg, __-------__-------) without entering the
HALT/idle mode (all my words), which involves shutting down more parts
of the CPU. You gave one method; I gave another. No HALT, no idle.

"long" periods. Define "long".

I don't want to define "long". Why do you suppose I put it in quotes
and gave you a "such as"? I could rewrite the sentence without using
"long", but I don't want to do that, either. You could have gotten my
point.

You're free to use "throttling" any way you want, but be prepared to
be misunderstood.

Assuming that you also don't want to provide precise definitions,
I will still ask you for a few yes or no answers:

1) Do you think "idling" and "throttling" are the same thing?

2) Do you think that MSFT XP should be expected to be "throttling"
while the OP is staring at his ASUS Probe temp figures just after
booting?

3) Do you think that the guy who warned the OP about BIOS and XP
idling differences deserved to be flamed by "strontium" (sp?) for
doing so?

I don't recall flaming, anyone. I was, merely, pointing out to 'other guy'
that his reply to my reply was redundant. And, if I were the other guy I
might be offended right about now. You, basically, called him an idiot (in
not so many words). I had assumed that he didn't read the whole thread,
before replying (hence my reply). You assumed he had and doesn't have the
intelligence to discern that I was talking about the same thing, regardless
of whether I said 'throttling' or 'idling'.
