Pentium M OC-ing

[Ivan]

I OC-ed Pentium-M from stock speed 1.73 (533 FSB) to 2.6 (800 FSB), and it
runs perfectly stable after 3D Mark 05 and Sisoft Sandra.

Sisoft Sandra even indicates it is almost equal to Athlon FX-57.

Since I've never managed to OC a P4 2.4 Northwood or a 3.0 Prescott over 5%
this is a dream come true. The question is for how long...


Any similar experiences?

Nice cpu's ain't they?As long as your temps are good and you're not getting
errors go with it.Might want to check for memory errors with memtest or
Prime95 etc.

Well, all laptop processors are extremely underclocked to get the better
battery lives, of course.

What mbrd is it plugged into and what are you using for cooling.

As long as it stays within temp specs and is stable you shouldn't cause any
life threatening damage. Have you run Prime95 for a decent amount of time
and Robert's CPUBurn to stress it.

Any similar experiences?

There are several Web sites which have reported good OC results with P-M -
IIRC there was a French site which had one -- a 2.0GHz rated IIRC -- up to
2.8GHz and there's
http://www.techreport.com/reviews/2005q1/dfi-855gme-mgf/index.x?pg=1 where
they got it up to 2.4GHz.

the motherboard is Asus P4GPL-X with Asus CT-479 converter and the
specifically tailored (aluminium) cooler that came with the converter.

BIOS always reads the same temperature - around 50 C, regardless of the real
speed, which indicates it reads something else rather than CPU temperature.

I shall try programs you suggested to further test the overclock.

Rgds,

I.

Another question is how long the battery stayed alive? And would the
laptop burn your lap if you placed it there?

That's funny you ask that, as my wife uses a Dell 600M with a 1.6 PM
which runs hot. If you feel the back of the ports they are all hot.
Almost to the point of burning your hand, in fact that is how I tell
it's time to get another RMA is by how hot the ports are. That and the
thermal design Dell uses is crap, I also missed out on the battery
return, mine seem to be good.

I would not even dare to over clock that beast, it's hot enough as it
is, and I think its cpu throttling as it is. I know that RC5-72 does
not run at full speed. I have a Athlon XP 1700 that crunches more than
the PM, according to the client.

As a followup my power adapter, or the motherboard ac plugin died.
Can't tell which as I do not have a mobil adapter to test with. All I
know it that it will not charge the batteries, the wife is now using my
backup AMD duron 800 Sony laptop. Which is about two years older than
her 600M, which was purchased in 2001 or that time frame.

So far so good the only problem she had so far was the fact that I had
to install java under ubuntu. As long as she can play pogo she is
happy, that laptop also has Open Office 2 on it, which might come in
handy. Yes it did come with Windows ME, I hope to keep MS off that
machine, unless I have no other choice.

I am just glade I did not overclock this machine, or my trouble's would
be worse.
