Bringing the Pentium-M to the desktop

Overclocked my donathen:

2.0 Pentium 755 to 2.3 YEY

How do the Dothans do for DVD ripping as opposed to the A64 and newer P4s?

Daewood · Jun 28, 2005

so will my P4 in my sig "feel" faster while multitasking compared to say a P-m at around 2.5ghz?

or would it not be worth the purchase?

The pentium-m will eat the P-4 alive, even when multitasking.

This P-m feels faster during apps than the 3.0 @ 3.8 and windows loads much faster.

That's a great score, what temps are you getting? I'm pretty sure i could match the clockspeed but high ambient temps prevent me from upping the vcore too much.

Has pics of a pretty nice mounting alternative which I think can be utilized, with the proper modifications, with both air and more extreme cooling systems.

Yeah that looks about like the method i explained to Jimbob a few days ago, he will try it when he gets back from holiday int wo weeks.

An alternative to the piece of round stock is the use of a "channel" or "U" shaped piece of aluminum, depending on the size and used with the "U" on its side. I found some ranging from 1/2" to 3/4". Cross cut a piece and you have the equivalent of the piece that was made out of round stock in the post that I linked above. Using the U-shaped aluminum would require only making the cross cut and then drilling the holes for mounting to the mobo. I believe that the only concern is whether the piece would be strong enough, but since the "leg" could be wider than the leg of the cut out round stock, I believe that it should be as strong or stronger.

50C idle/+60C load. Ambient temp 24-25C.

Yeah thats what i did for a mod on both of mine. I just used 2 3/8 ' bolts though and offset drilled the holes so less ginding of the inside was required.linky
It makes for an abundant possiblities for cooling

You may have to undercut the base a bit to clear traces or resisters on the board. This is certain on the P4P800 SE as one of the holes has a resister very close to it.

I've done some reseach to compare the Asus probe readouts with the ones of my Aerogate. See here.

Added Datura's excellent contribution on peltiers, and a bit about temp monitoring.

I thought it was better to get the slower chips, so that your multi won't be so high.

With the newer BIOS'es that doesn't matter much anymore because you can change the multiplier in BIOS.

@ Sit Guinhill: Thanks, added

for my friends watching, expect some pictures soon
