Prescott capable MB replacement

[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:

(I am not affiliated wit that WEB Site, just providing a pointer to so
info on the subject of my post)

Thanks for your time…

This site has pictures and data on motherboards. Either an
865PE or an 875P board would work. The 875P overclocks better.

I notice there are some Gigabyte boards that have the
ultimate Vcore solution. They have three phases on
the motherboard, and if your CPU cooler is not too
big, there is also a VRM slot on the motherboard,
where a separate three phase auxiliary conversion
circuit fits.

Picture of DPS2 module fitted to motherboard:

Anyway, with the pictures on the Mobot, you should be
able to locate a motherboard with "fat" VRM on it.
I suspect most motherboards will be three phase, but
you may get lucky and find other configurations.
The Gigabyte counts as six phase, when the DPS2 is
fitted, but I have to wonder whether 40 amps finds
a low inductance path through the connector.

I have an S478 motherboard, but I cannot recommend it as
being perfect. While the Vcore has stayed cool, the DRAM
uses a linear regulator scheme with MOSFETs that run at
40C+ (measured with a thermistor). There are enough shortcuts
taken in designs out there, that you could spend all day
reviewing pictures of motherboards.

Good luck and good hunting,
Paul

I have the EPoX EP-4PDA5+ Socket 478 Intel 865PE ATX Intel
Motherboard.
