Prescott capable Socket 478 MB's

[Mike Webb]

I put together a P4 3.2 system about a year ago, and have had
intermittent problems with cooling, if I do any serious
computing...(i.e. Rendering a Video)...I'm not a gamer so I seldom
have that kind of a load on the system, but when I start up something
like Nero Recode to re code some Video files I have, the PWM Temp gets
to be quite high (70-80 C) and I abort it.

Research seems to indicate that my ABIT AI7 MB, although offering
"Prescott Support", does not really have very robust support for the
Power hungry Prescott. Has anyone had any experience wait a Socket 478
Prescott capable Motherboard, they would care to recommend????

A good article on the problem I am Seeing is located at:

Thanks for your time…

Well, I still think you've got funky temp. readings. But I've built two
systems with the following board. One is a rock-solid stable and fast
gaming system in a portable case. My wife's system had a high-end
thermaltake brand power supply die on her, and it destroyed her 865 chipset
mainboard. I replaced her dead motherboard with the following also. I was
just looking for something cheap to rebuild to test all the other components
with. It's been rock-solid stable and faster than the 865 chipset mainboard
that died. Unless you have a ton of PCI cards, I could recommend this
(typing on it now). I don't use the onboard video or onboard sound. -Dave

I just built a system for a friend with a P4 3.0 Prescott (Socket 478), and
it runs around 45°C in XP at idle in a 24°C room, though I haven't stressed
it much yet to determine maximum temps. It has a Zalman 7000AlCu (aluminum
and copper) HSF installed with Arctic Silver 5 compound. Another
photo-editing box I built ran for the past year on a 3.0 Prescott and never
came even near the high temps you're experiencing under any conditions. I
just recently replaced that CPU with a 3.4 Northwood.

This computer has a P4 3.4 Northwood (478), which run cooler than Prescotts,
and a Zalman 7000Cu (all copper) HSF installed with Arctic Silver 5. It is
running at 39°C now in this 26°C (78°F) room, and runs in the low 50's when
running Nero Recode 2. The highest temp recorded by MBM5 is 54°C since it
was installed one month ago, and I do quite a bit of DVD recoding and other
video/photo work. I previously had a 3.0 Northwood with the same Zalman HSF
and Zalman compound (not Arctic Silver 5) and it ran about the same temps.
The 3.4 should run a bit hotter, and the AS5 compound was probably the
difference.

You might also suspect the software or hardware reporting the temps, and I'm
not familiar with PWM. What temp is reported in the bios when idling?
Because of HALT processes in Windows 2000/XP, the temp in bios should be
higher than idling in Windows. Also, touch the HSF (after touching the case
first to eliminate static) while running to sense the temp. It should be
warm but not hot. Not scientific, but it's an indicator.

Your temps of 70-80°C are far too high even with the stock HSF, and I would
suspect something is not normal. Perhaps the CPU isn't seated properly on
the HSF. I would reseat it with a good compound or buy a good aftermarket
HSF, like a Zalman or Thermaltake, and install it with Arctic Silver 5.
Note that this 7000Cu is double the maximum weight specified by Intel for a
Socket 478, which is not a problem unless the box is moved or otherwise
jostled around. The 7000AlCu is right at the maximum (450g) but doesn't
transfer heat as well.
