Celeron 1.3Ghz @ 2.92Ghz = 125% overclock on stock cooling :D
:toast:
very nice
whoa, lets see some super pi times! thats awsome!Quote:

Bravo :clap: , but till now is been found, that Vcca is not safe to be kept over 3V [double the value & double the max current recommended there] !! long term. Now since IMHO you made world record with C_M, it is time to lower that voltage not to kill something!. But make a SuperPI result before that !! :) to see us the 1M result!Quote:

After lowering OC, test it with THIS : already prepaired 16kb test & tell us till where (clock!) it can handle it
:clap: again ! :) [if is not just a April Fools Day joke ..:woot: ]
Thanks guys, indeed 3.3V Vcca is a little extreme, but afterall it's a $40 CPU :). Actually i was thinking of extra mods for the adapter to allow more than 3.3V for Vcca after i'll switch to a little better cooling.
The Celly is indeed B1 (older) stepping and seems to Prime just fine at 2.6Ghz / 1.42V Vcore / 2.95V Vcca. I've tried a SPi 1M at 2.8Ghz, it's in the 31's on a really dirty OS with no tweaks ... remember this is P4GPL-X and it's at least 1s slower than the P4C800's out there at the same clocks.
That's impressive for a B1 stepping. I wonder how a C0 Celeron would do?

I think it is time to check for its datasheet to see if there would be any chance to modify CT479 adapter for those C-Ms (core Solo-same pinout like Duo). We need to compare Dothan 2 Yonah pins differences since I believe the differences are not greater than at times of P3 to Tualatin mods era; IMHO Yonah should work on same Dothan Bios-es; just minor core differences with core production shrinking I believe ... start "brainstorming" :) ...
If this was possible.. Celeron M 4n0 .. "modded" to run on CT-479.. I guess this would aslo apply for Yonah.
As a budget system capable of "extreme" benches it sure would be nice if it was possible to run thos new Celeron M's on Asys CT-479 compatible board (I have "a few" btw).. :)
There is NO WAY to let 479 be compatible to 480, they are so different, don't even think about it man :eek:
Sort of off topic here, but what is the max "safe" voltage for Vcore on Dothans? I have mine running 2940MHz (12x245) @ 1.775volts, VCCA @ 1.8v, Vdimm 2.65v, AGP VDDQ 1.8v. SPI 1M 26.420secs
I'm not getting much droop since I've done the Vdroop + the combined Vdroop+Vcore mod, about 16mv according to onboard, DMM about 1mv.
Running P4C800-EDlx on 1024beta bios. Hipro5 mods on adaptor. Chip is watercooled so I'm not worried about temps, Load is at 33C.
I believe max.1,65 for air; maybe 1,75 max for water ... :)Quote:

Might be time for me to find a 5K Ohm resistor to adjust VCCA higher than 1.82 to see if that helps.
My temps haven't gone past 33C yet, but it is not summer. In summer I think maybe 36C max temp.
I think it's time for me to reclaim my crown again...:D
It's not a celeron, it's a PM750 btw.
I need to figure out where to get a 5k ohm 25 turn trimmer locally, the only ones I can find are 10k ohm.

Very impressive ! What mobo were you using and what was the ambient temp ?
P4C800e-dlx and temps?
no idea, I don´t trust the Winbond-chip ...
but stock cooling hmmm I think about ~55°C
C_B is that win2000 or XP? That time you've got is very good, faster than me at lower clocks :D care to chat a little on tweaks?
that´s WinXP
in my gallery u find more good benches :D
http://www.forumdeluxx.de/gallery/sh...&what=&name=&=
okay my tweaks?
hmmm disable all USB Network Sound options
a new winXP installation with Windows default Grafics driver,
defragment your partition
goto Performace Options -> Advanced
vis.effects for best performance
CPU-scheduler to programs
Mem to systemcache
pagefile=0
reboot with diagnostic start (msconfig) to shut down some services ...
set SuperPi to realtime mode
done :cool:
Apart from the "disable all USB Network Sound options" I've got them covered, can't wait to get my P4C800 sorted out again for such events :D we should have a little mini comp for ourselves here, do it for the pride :toast: what say ye gentlemen ?
OK, i'm in with my poor P4GPL-X :).
Now i have here for testing Celeron M 370 1,5ghz @2400mhz @1,4v
I will try moore :rolleyes:
Breaking up the dirty thirty with my humble celly.
Mobo is P4P800SE. P4GPL-X sucks indeed.
BTW, processor hits a wall at FSB 186 in P4GPL-X. Moved to a P4P800SE, same vcca, same vcore, boots with no problem at FSB 200. Pretty strange since my P4GPL-X ran flawlessly a P-M 750@2.8GHz. The processor is not the problem, the mobo is not the problem, where the *^^&*^ can the real problem be?
