3. Max before was 180 x 10... Can now get to 187 x 10 stable ... and if I drop down to a 9x multi I can actually get the FSB up to 200MHz whereas before it was 180MHz max ..,. as load is applied to the CPU it bombs @ 200MHz ...
4. So maybe that's the problem here and not the CPU or mobo? Am tempted to try a better cooler on the NB too - see if that helps

ad1. - nice burn-in of the whole system! :)
ad2. - normal & better so ...
ad3. - some previous job did the job! ...
ad4. - the problem IMHO are other (notVcore) voltages supplied to the chip; so after some burning-in, the chip /also chipset& Ram/ can actualy work with lower ones than supplied; so, with the ones actually supplied, OCs better ... about NB cooling, try only mounting a small fan@5V on the top of actual HS ...

I like big butts and I can not lie.... Ooooooooooh dear I have been drinking and I LOVE IT... OOH YEAH BABY!

Err... What the hell? I didn't post that ^^^?

Think someone must have been using my PC on saturday night (the b*)

hey spajky i found something about C-step dothans having "optimised voltage ID", could that have something to do with the fsb limitations? :confused:

As before...

My 1.3GHz *Banias* (0.13u) Pentium M running in my AOpen i855 mobo... 10 x 187 seems highest max stable CPU clock but dropping the multi to 9 gets me up to 195MHz FSB. At stock volts too... RAM is plain crucial PC3200 3-3-3-8 / 2.6V (running @ CL 2.5-3-3-7 / 2.6V because that's as high as the timings and RAM voltage can go on this mobo)...

Been priming for 20 minutes so far without error... Off to sleep in a mo (it's 3:40 am here) but will leave Prime running. Temps are 36 case / 50 CPU at the moment (in my LC11 with the 80mm case fans @ 2000RPM and the fan on the swifty MCX 4000 @ 5V)

Edit: Dropped the fans down to 50% on speed fan after I posted this... Been running for 40 mins now without error. Temps have gone up to 39 case / 52 CPU... Really got to go to bed now... 4:00 am is not good... Working in a few hours...

Edit 2: Did just over 6 hours before I stopped the torture test... Temps stayed the same too. I won't go up to 200Mhz though... Maybe another 10 days of DivX encoding will get it there...!

anyone find a way to overcome the fsb limitation ? :)

keep burning them in seems to work pretty good from malfunction! experience

Worth a try... I can prime for about 20-30 minutes @ 200MHz now (though the USB ports die before prime does...??)

**FREAK**

have bought a 360J,

oc result was FSB 180 =2,52ghz but not stable...

@175mhz FSB =2450mhz it was 100% stable....... :(

don`t know, can oc to ~180mhz FSB but i can not run a benchmark, there will be a restart when i start Bench or a Game....but i can hear music, can surf in the i-net,.....also @1,6vcore....

i also disabled onboard-stuff, but no improvement.....

Who knows .. :)

i recently repaired my adapter.. when removing power-connector i somehow replaced 12v and 5v wires and just noticed it by looking others pictures.
silly thing is that adapter worked with wrong voltage..
also i think it doesn't need 5v, the missing spot where that larger capacitor fits, measures 5v from one hole..

btw, you needed markings from chips on adapter.. i have few.. don't have a picture because i don't have digital camera with acceptable macro..

2.35 Ghz....:(

He He
Returned to aircooling....watercooling made the bios run 120°C/-120°C....
Ce M 370J (1.5 Ghz)
asus P4GD1
PCI VGA Card
Bios 1005 (tried 1007 bêta but it won"t run...)
Dual-Channel 2-3-3-6 (Corsair....2x512)
Memory at 392 Mhz

Cpu @ 2.35 Ghz (157 Mhz FSB....) Can't get any further
Vcore @ 1.325 V
Mem @ 1.60 V
Chipset @ 1.50 V
Hyper Path activated
Azalia disabled (sound)
PCI-express freq. @ 105
PCI @ 33.33

Set the memory to follow FSB won't run
I can't get past 157 Mhz FSB.....

Have 275 Mhz mem...so i can test next synchronised RAM ratio...

Any ideas??

(from later...)
That's it...
've set the PCI-epxress frequencies to 90 Mhz....
And i can go up to 173 FSB (RAM@396 in BIOS so 183 i think....2-3-3-6)
2.59 Mhz
V Core is 1.40 v(temp is 50-53°C... :p: )

caater , thanks for info, will check/search for datasheets later!

BTW, has anybody thought about some Air-Peltier element cooling (Slk900cooler+80W Pelt with coldplate gor GPU´s) for C-M ?

see those two cables going into the base of the sink....

9C idle - :P

the peltier couldn't handle the chip overclocked on load though

(80W @ 12V)

that's what i experienced with 60w pelt + water.. less than 1.45v and chip was cooler than roomtemp.. over that, temp escalated dangerously.. when i saw 80Cs in bios, i stopped the attempt :-P

so dothan isn't THAT cool when overvolted :)

I tested with and without +5v, +12v and both grounds- needs all of them or no boot.

looks like we have to move to the 170Ws :)

prob need a nice swiftech heatsink+delta to cool it :)

You all forget that Intels TDP is not full load power, but less; on TDP you have to add 35% approx. to get really full load dissipation (to for example compare to AMD power dissipation). :)

Bump ye'old thread!

Alrighty, I just picked up a used 350J from ebay and I'm testing it right now. My first go was a little dis-heartening, the CPU hit around 150FSB before having problems (default VCORE). I reflashed (P4P800-SE) and messed around with the jumping settings on my adapter a bit. I got it running 167FSB @ 2.17Ghz, undervolted to 1.16V core! Now I must mention I did have problems with the adapter suddenly not wanting to run 150-180 ish FSB speeds with my P-M 730 (but the CPU can easily do 200x12 on the same adapter) so I dunno, bugs whatever. But If I can hit 200FSB hopefully those issues will not be a problem. I just wonder if this Celeron M can do 2.6Ghz...

I would be very positively surprised if your 350J did 200.
So many that have tried... and not succeded.. not very likely.
Had similar experience as you "pongi"...with my 350 M.
No point in increasing VCore..
Actually... Unlike my two Dothan's (730 and 740) OC'ing with increased VCore usually resulted in "no-boot" or freezes in Bios.
I left the VCore to Auto (P4GPL-X) = 1.275 and it went to 164x13=2.13 where it "hit the wall" (likewise with my two "Dothans".. at 213x12=2.55).
Strange that CeleronM :confused:

Was your Dothan Celeron M's the B1 stepping or the C0 stepping?

update: I'm up to 170FSB now, 2.2Ghz @ 1.2V.

I also have a C-M 350 (non J) that hits only 160FSB, on a good day. Same ol cap on most of those B1's.

I'll check up the stepping tomorrow.. Still I must say I think the Celeron M is a good performer, ecpecially considering it's low price..

I got a £20 Celeron M 360 off ebay yday :) stopgap till my bday till i an buy real dothan...

bought a ct-479 aswell, coming tomorrow :)

now i just need a compatible mobo (p4p800se), doubt p4p800-x will work..

I have one Celeron M 350J, using P4P800SE with 1009 bios, I can't change FSB in bios, neither memory speed. I only can reach 140fsb stable. Any beta bios that I can use to adjust FSB and memory in bios?
