Nothing revolutionary, just some info.

I was always curious as to if the mobile P4 (not the DTR) chips were directly compatible with the 865 chipset. I wouldn't want to take a step backward to get an 845 board which is known to be compatible just to screw around. I have read alot about the Celerons (most through Karaktu's threads) that some of the Asus boards were directly compatible with the Celerons, but with many of the 865/875 boards (including Abit boards), you either had to bend or remove processor pins which is not my cup of tea.

Curiosity got the best of me about the mobile P4s so I took the plung for $50. The chip was a 1.6 P4 as spec'ed here. All seems fine. Bootup was normal. The multiplier defaulted to 12x as it should. Cranked in 200 fsb and booted right up at 2400. Seems like 2600-2700 is the max, but not bad for $50. No HT, but oh well. About all that I do not like, is the voltage does not go down to the 1.3v as spec'ed. It's lower limit is 1.575v on this particular mobo. I was really considering building a custom cased low noise comp (but not the cramped SFF) for the living room, and 1.3v would have helped. Anyone know of a hacked bios for an AI7 that remedies this?

I too was wondering about this... i just got an 865 soyo board from newegg and my p4m will not boot at all. i have the same chip as you as well. i dont think im taking my swiftech off my cpu in this machine to test it either :)

any pin mods that need to be performed?

I tried 2x 1.8, 1x1.6 and 1x1.4 P4M on a Asus P4P800 Deluxe and one P4C800 Deluxe with no problems at all.

I did not need to perform any pin mods. Are you positive you have good cooler-to-hsf contact? The desktop P4s have the heat spreader and the mobiles 1.6 does not. I have heard that some desktop board fan brackets do not allow good contact. Just a thought.

well, when i took the hsf off it had a nice little imprint in the thermal pad so im pretty sure it does have good contact.
