Have you managed to get anywhere with you idea's ???
.. no ... (I do not have the Cpu & MoBo/adapter yet to measure stuff myself & try to mod it by myself; sometimes in the future months maybe...); still studying pics of the adapter ...
Right...
Have received the Ce M370....
Tried to mod the waterblock.....done it :)
Mounted motherboard and RAM (2x512 cas 2) and cables.....nightmare (with 2 RAID set...)
Alomost done everything...damned heat sensor plug 've gone wild.....from the waterblock.....downside......have to re-do everything....
Guess i'll only burn my neighbour car....just to unstress......or yel "RRRaaaaaaa"
Don't know.......maybe robbing a bank......
Well, have to get back to work.....
:)
I have it totaly stripped out ATM, so if you need any further help just ask.Quote:

If you don't, (the banny's stock vcore is 1.484 right?), then you need to connect VID1, VID2 and VID3 to a VSS (see pic a).

you can just put a square of copper wire around the four pins (as they are in a square formation)...
I use copper wire ripped out from ide cables.
Yes multis are unlocked. :D
I will give that a try in the next couple of days.
sorry i meant vcore... :PQuote:

1.485 is default.. :D
Ok
Then just ground the VID5. This won't change your stock multi, it will still do 1.484 if you clear the cmos, this just changes the vcore for anything start VID5 normally = 1 (i.e. 0.7V to 1.196V) - if you set to them you will be given a range from 1.212V to 1.708V - that is, if you set 1.196V it will boot at 1.708V, and so on.

That pic is the pic of the socket, so remember that's inverted frm the cpu - I normally put the wire on the socket 'cause my hands shake too much to put it into the pga.
so basically I, put connect the vid5 to vss to give me 1.72 v :D

Spajky
Just some information for you that might help.
I did a quick test to check what Voltage feeds the CT-479 uses.
It needs both -ve and +12v & +5v to function.
Thanks, I could imagine that; but if you look closely around left upper corner of the adapter, there are a lot of components "missing" (by the way, 2 small MosFets), could be that that was primerly ment to directly feed Cpu Vcore, or, the adapter is already prepaired for next version, supporting dual core CPUs! Who knows .. :)Quote:

Strange things happening yesterday. My Banias (Pentium M) that lives in my HTPC (in my AOpen 855 board) was overheating a bit after 14 solid days of DVD --> XviD... The chip seemed OK but it was heating up the case a bit and the fans were ramping up... And obviously noise is a big :nono: for my HTPC...
So I thought - sod it - I'm going to replace the existing hack mounted passive heatsink with something that bolts to the mobo and has a fan on... Enter Swifty MCX4000 and some scary mounting (99% certain I've rounded the edges of the core as I couldn't use the stand offs because they were too high). I got much better temps (even with the fan only at 5V) but also better overclocks... Max before was 180 x 10... Can now get to 187 x 10 stable (* haven't fully prime tested it yet) and if I drop down to a 9x multi I can actually get the FSB up to 200MHz whereas before it was 180MHz max even with a 6x multi... Don't get me wrong as soon as load is applied to the CPU it bombs @ 200MHz but this is with bog standard PC3200 CL3-4-4-8 (Edit - actually default is 3-3-3-8) that (because of the 855 board) can only run @ CL2.5-3-3-7 @ 2.6V... 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
What temps are you having now at 187x10?Quote:

but did not want to boot at 9x multi in a p4p800se

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:
http://www.vr-zone.com/?i=2468
IMHO no ...
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...??)Quote:

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). :)
yup - mine requires all as well or no bootQuote:

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?Quote:

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..Quote:

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?

All of the dothans are all pretty close together in clocking ability and pretty random (as in I've seen 730s do 2.9GHz and 750s which didn't make 2.5GHz).Quote:

The Celeron M 350 is now installed in a P4P800-E Deluxe.. have not tried any more than 13x164=2.13 yet..
My Celeron M 360 is installed in a P4P800-VM.. and is as of speaking running 14x160=2240... both system at stock VCore (1.25).. The P4P800-VM has very little in Bios for OC'ing, so I'm using Clockgen from Windows (Startup folder).
These system are built as low-budget/good-performance.. both with softmodded 6800LE. I think Celeron M is "value for money".. :D

Seriously tho.. who ever said Celeron's were slow :D
I have WR in highest clock and fastest superpi I believe
http://valid.x86-secret.com/show_oc?id=48040
Why isn't PAT enabled? Prob can get an extra second or so..
And does it benefit from extra vcore or is it a bus limitation?
I must say again that these Celeron M really surprises me.. positively.
OK.. no one (AFAIK) will do FSB200 (100% OC) but still they perform more than adequate.
My latest system.. still under testing.. manages 65% OC.. so far.
I won't be greedy though.. This is on default VCore.. in a P4P800-VM board.. accompanied with a 6800LE@16x5vp.
PAT's disabled because my ram couldnt do 2-2-2-5 @ 226 with PAT lol..Quote:

Hi
I´m new here and searching for informations as I want bulding a Dothan system.
On the Intel datasheets I found the new Celeron versions as the 360J have different corevoltage. The specs say 1.004 - 1.292V now. Someone knows what corevoltage the CT-479 adapter will provide then now with this Celeron?
I will go for the P4P800 SE board. What bios version is the best or does it make no difference if it´s 1008 at least.
Thanks.
i posted that a long time ago, and I hadn't seen anything near as quick as 32.266 at the time..Quote:

The Celeron-M 360J gets 1.294-1.314 V on my P4GPL-X. sSpec-No. SL8ML.
But I have the problem with fixed Vcore, too. Same as lawrywild. No way to adjust a higher voltage. Tested with 2 brandnew boards, both the same. So my C-M is a poor overclocker and at 150 MHz FSB it hits the wall. And without the chance to give it any more voltage this is very disappointing.
I tested the boards with a P4 Northwood and it gets 1.58-1.60 V instead of 1.5 V default. Quite a bit overvolting. With this CPU I can increase Vcore. But not decrease...
Very weird. Both boards show the same behavior.
Is it possible that ASUS assembled a series of faulty P4GPL-X? Maybe some components are out of tolerance.
Greetings,
Uschi.
yeh possibly that or I have come to the conclusion that the bios doesn't contain my cpu's microcodes, stupid ASUS idiots..Quote:

I just had a phone call with an ASUS employee a few minutes ago. He told me that's the problem with OEM CPUs. It's microcode/ID is not properly implemented in BIOS. Could be lucky my CPU is running at all.
And no one will write a new BIOS for some OC enthusiasts...:eek:
He advised me to buy a retail prozessor.
Default Vcore for C-M is 1.26V - Cpu microcode has nothing to do with Vcore, Vid pin combination and Vcore controller chip on MoBo does! Search for Vcore Vid pin trick mode ...
Hmmm have been experiencing some strange side effects of using a C-M on a P4GD1 motherboard. To start with the chip correctly instructs the board to supply 1.26volts to the chip, however, My board has a vcore mod, adjusting this in the usual manner at this voltage causes the vcore to do DOWN rather than UP, why is this? Next, THE P4GD1 DOES ALLOW YOU TO RAISE THE VCORE IN THE BIOS SUCCESSFULLY, BUT chosing a settting lower than 1.55volts reuslts in a undervolt reading at the core, above and it is the usual overvolt that the board "normally" supplies (for instance when a dothan or P4 is inserted). When vcore is abouve 1.55volts the vcore mod also starts behaving normally. Has anyone any idea why this would be? effectively it is of little odds, increased vcore has little effect on the overclocking potential of the C-M but I'm curious as to why this vcore issue arrises.
couldn't really find anything much on this, would you care to point me in the right direction?Quote:

You need to open/short some those Vid pins on MoBo´s back or on socket from pinhole to pinhole with tiny tiny copper wire taking care not to short something else & not to miss pins! Take much much care!!! This way you trick the MoBo´s onboard voltage regulator chip, that the default Vcore is higher, bios than allows going even higher, do it in small steps!Quote:

Please look at CPU-World: SL8ML. This sSpec-No does not appear on Intel sSpec Finder sites and there is no RJ- or RH-No. Seems to be just an OEM CPU, produced for IBM.
So my P4GPL-X correctly hits the maximum core voltage of 1.292 V.
I don't want to do any mods with my mobo so far, because adjusting vcore MUST work. I'm looking for a solution and can't believe ASUS 'til I have a proof, that OEM CPUs do not properly work.
if you mean the 1.55v "uwire" mod, I've already done that, or is this something else, like tricking the motherboard into thinking its a retail proc?Quote:

But why can vcore be adjusted on a P4P800-SE and NOT on a P4GPL-X with the SAME CPU?
I'm still looking into a black hole...:confused:
probably some connection for some Vid pin on 2nd MoBo different; who knows ...Quote:

Just tested clockgen on an HP s7320n and it works great. Its an ultra small SFF pc with normal 200GB hard drive and dvd burner. But it is FSB locked so it never goes over 2345Mhz. At that my SP1m is 37.186 seconds. Not horribly great but ok seeing it gets 55 seconds stock.
Here is a PIC

DON'T !!! (we do not need anymore dead heroes!) Isn't 120% OC enough ??? :cool:Quote:

C-M 360 = 13W TDP! Thats Intel data; but ... Real (not Intel´s TDP) thermal dissipation is around 35% more at real full load (as for example AMD mesures it!)
With so overvolted & OC-ed your max.real heat dissipation /real full load/ is more than 60W !!! "Thermoelectric migration" is probably slowly killing your CPU right now! Can easily happen, that after a time, you won´t be able to run it neither @ 3GHz totally stable anymore !!! Think about it before is too late !!!
What kind a TEC you have ? (nominal voltage/watt-age) With how much voltage you are running it ?
Hey Johnny, what resistor values you using to push 3.1V VCCA? Actually I'm more interested in the 2.5-2.7 range if you know.
Rather dramatic.Quote:

:D enough ? I don't think many people round here understand the word "enough" :stick: Just Kidding man :toast:Quote:

However I fuly understand and respect your concerns Spajky as there may be those out there with more expensive chips wanting to do the same thing. Your are right to stress the upper limit of the VCCA mod, that's an easy way to loose a perfectly good chip :slap: We'll let the chip burn in for awhile now and see what it does next :rolleyes:
Pongi, will a resistance value measured directly from the board as in not the actual value of the resistor but what it appears to be attached suffice? I believe that the onboard resistance is something like 1.2kohm but dont quote me on that, check Georges (Hipro5) post on the subject in the mods section for the adaptor for exact values. I'll get you a number tomorrow nite at the soonest :toast:Quote:

ewitte, that's an odd celeron M, with 8x multiplier and capable of 297MHz FSB..
Don't pay too much attention to the numbers. If you look at it in clockgen with the correct chipset/timer it says about 148-149FSB. I can't change the multiplier or voltage :( I'm seriously looking into popping a 745 in there.Quote:
