Solved the mystery with the so-called celeron-m fsb capping. Looks like there is a P4GPL-X/P4GD1 BIOS problem (I suspect Assus intentionally crippling the bioses to a certain fsb as they have done with P4S800D-E "i875 killer" and Asrock 939dual-sata2). Using clockgen, I got the same results as on P4P800SE. Otherwise, system refuses to start when going over FSB 186 no matter what.

lol so "assus" (lmao) cripples the bios for celery's only? cuz pentium m's dn't have fsb issues did they?

errr no, the limit is ont he chip as folk have used various boards (not just Asus) and encountered the same problem. Anyhow, with a bit of VCCA you can easily get past 200MHz...

i need a bios for the p4p800 se board for my rig i'm trying to build, would someone be nice enough to link or upload it? plz plz plz?????


what is vcca? for the north bridge?

Usually the manufacterers Website is a good place to get Bios versions..
Regarding mthe "VCCA-mod" it should be found here in the thread.. and elsewhere... (Not recommended for the lesser experienced.. and better reserved for "frying" Celeron M chips)..

i_found_nemo, frankly said, you should find another thread to have fun in.
The vcca mod is applied to the CT479 adapter and is described in the respective ct479 mods sticky thread - look for the post made by Hipro5.
johnny, the chip does not react to vcca, starting from 1.7V all the way to 3.2V.
I can tell you what happens: exactly at FSB 187, the board refuses to start. The chip can prime flawlessly at FSB 186, 2V VCCA, increasing the vcore or vcca (vdd is at 1.8V) doesn't help a damn. Using clockgen, I got past FSB 195 quite easily. Since the bios does not allow me to increase fsb but clockgen does - and mobo can handle it, guess who might be the problem.

Im on 2545 mhz. End is at 175 fsb no post whatever i do.

Little bump to this old thread
24/7 clocks for my new low-budget rig:

Celeron M 360J (C0) @2342MHz (14x167) 1,35v, inbox cooled
Asus P4GPL-X + Asus CT-479
512MB Winbond BH6 167Mhz 2-2-2-4-2 (single channel )
SuperPi 1M - 39,812s

Not bad at all for 25$/20€ CPU
FSB stuck @~170 for this one.

EDIT:
Got 2x256 Corsair BH5´s
Celeron M 360J (C0) @2342MHz (14x167) 1,35v, inbox cooled
Asus P4GPL-X + Asus CT-479
2x256MB Winbond BH5 167Mhz 2-2-2-4-2
SuperPi 1M - 37,500s

EDIT2:
Got new Cel M 350J
Max FSB ~185
Paid ~10€ for it

Intel Celeron M 350J (C0) 1300MHz @2405MHz (13x185) 1,28v
Asus P4GPL-X + Asus CT-479
2x256MB Winbond BH5 185MHz 2-2-2-4-2
