A hot running SL6PG

[Stephan Carydakis]

Hi All

It seems there is nothing wrong with the CPU, case ventilation or anything
else to do with insufficient air flow/cooling. The culprit is . . . (drum
roll) . . . The ACPI multiprocessor HAL (cheers and jeers).

Something I read about massive amounts of interrupts as well as what kony
said about no HALT (same thing I think) with ACPI not being enabled in the
initial install, triggered a thought (oh the agony). I went back to the
ACPI uniprocessor HAL and voila, idle temps down about 12c on socket and 9c
on CPU. Full load down by about 5c all around too. The idle to full load
spread now sounds much more 'normal'. I am currently running oc'd @ 3519
and a stock Vcore of 1.55v with an idle of 41c on the socket sensor and 53c
on CPU sensor - much lower.

So what's going on? ACPI uniprocessor HAL = cool maaan. ACPI
multiprocessor HAL = put on your shorts and grab yourself an ice-cream? With
the ACPI MP HAL active, the CPU usage was still 0% (or very low like 1, 3
etc) at idle according to all my monitoring programs (task manager, MB5 and
Asus Probe). But I still had idle temps of 61c on the CPU sensor. What's
with that?

Again, thanks for everyone's time and input .

Steph.

If you only had 1 processor (and you HAVE to with a pentium 4), why did
you enable multiprocessor stuff at all? Anyway, thanks for posting your
solution, I'll remember it for future mysteries.

A SL6PG has HT. So to utilise hyperthreading on win2k, you need a
multiprocessor HAL.
