Multi problems with Dothan + ct-479 on p4c800-e

I Flashed to 1021 bios for p4c800-e, installed adapter and dothan 760 533 fsb processor, set jumper pins for 533 fsb cpu, and this is what I get:

It boots with 6x multi and I cant seem to find anyway to change it. In the bios, it show the cpu ratio as LOCKED :( any ideas?

I figured it would at least boot with the 15 multi which I believe is def. for pentium m 760 533 dothan, but no luck.
Crystalcpuid screenshot shows the same:
http://pic8.picturetrail.com/VOL256/...6/94557496.jpg YAY! -59% overclock :)

I have a p4p800 here I can try it on too, but I will need to force flash it to the p4p800se bios. This is possible, no?

What a nice underclock :woot:

Props goes to zawanao, at EOCF, who showed me the ways. On the 'Function' pull-down menu, click on 'MSR Editor'. Read address 0x0000199. The setting for EAX will be 0x0000xxyy, with xx being hex for the multiplier, and yy being inverted hex for VID. I haven't personally been able to get VID changes to reflect against actual vcore, but multi adjustment will change....at least in Windows.

Multis, for those who aren't savvy in hex (which, I'm not...I use an online converter :D):
multi - hex
6 - 6
7 - 7
8 - 8
9 - 9
10 - a
11 - b
12 - c
13 - d
14 - e
15 - f
16 - 10
17 - 11
18 - 12
19 - 13
20 - 14
...and so on. So, it would be written 0x0000c20 for a x12 multi.

There's no G in hex dude. They stop at F, which is 15 ;)

Ah, well you see, there it is there...I told you I wasn't savvy...*previous post edited* :slapass:<---me

It is still a little unclear to me....
I can make the value under eax change to hex for whatever multi I want, but the multi does not change in windows.

Hmm...I don't know. The change would take effect, once written through crystal cpuid, for me. I got the impression that it wasn't a physical change, but rather a "software" change only, but it would reflect in CPU-Z at least.

On the processor box it states that the chip runs in performance mode(2ghz/1.35v) and also battery optimized mode(800mhz/.998v)

My chip seems to be locked into battery optimized mode:

I wonder if raising vcore would solve this. Maybe when the chip senses low voltage, it throttles down?? Havent seen this in any dothan threads yet though.

looking over this thread and seeing that i will be doing the same thing i was wondering, do you think that i will run in to those same issues. Although i am using the P4C 800 deluxe E.

Will I have to flash My bios to do this?

You will have to first flash to 1021 without the adapter installed (i.e. w/ a northwood or prescott installed). I think I remember seeing that fugger and possibly one or two others, ran into problems on initial flash, and had to re-flash w/ the adapter installed to clear it up.

And i havent gotten the chip yet but he said move a jumper i beilive for a 533 where xactly would that be

If you look at a picture of the adapter, you will see. ;) There are two jumpers and a FDD power connector on the board. Those jumpers dictate FSB.

what is this =\ I'm building a system based off dothan + P4C800-E deluxe and I don't have any northwood or prescott in my posession. that's what most would call "just great."

Buy a cheap Celeron, or something and then just take it back the day after. Thats what I'm doing when i get mine Dothan Set-Up.

heh luckly im still on my 3c now so ill have it running soon but can someone gimme a link to the flash site lol :banana:

doubt this has anything to do with it...but go to start/control panel/ power options and change it to a desktop cpu...still doubt it has anything to do with it...but I'll say it anyway :)

EIST tool, or RMClock Utility may help you here.

I hope you find a fix, k|ngp|n. This thread has somewhat dampened my spirits considering I will be attempting a similar build.

no kidding. If I can't change my multiplier AND have to flash the bios with some P4 then I'm looking at a long road of difficulties. (I guess I can just buy that cheap Celeron but I don't want to have to keep doing it over and over again to reflash the bios over and over again :stick: ) Of course, I havn't heard of anyone else having problems with this - hopefully my build won't have any problems either.

I was thinking about buying one of these just for the sake of flashing the board. After everything is all good and kosher with the Dothan, I'll just slang it on ebay.

you'd be better off spending the extra dough and getting one from a retailer like CompUSA, then getting a nice fat refund that just happens to be equivalant to what you paid for it. :)

Thanx for tips guys.,,,definitely haven't given up.
Work contraints have kept me from spending more time with it, but I will have all weekend to work with the dothan kit.
Kunaak,
I already tried the eist tool with no luck. I will try rmclock.

I bought a prescott 3.0e eo stepping to flash the board over to 1021 initially. THen I put the, dothan in and it booted and went to post just fine. I should reflash the 1021 bios with the dothan installed and see if this helps. The chip seems to be locked from within bios. Still thinking a vmod will "wake it up".

In the mean time, I put the prescott 3.0e on DI just to see what it would do. All I can say is WOW!! these 3.0e EO's are really nice clockers. Hoping to break 26sec superpi 1m @5ghz+ on a barebones p4p800 by sunday. I'm at mid 27's now with 328x15 5/4divider 5-2-2-2 pat enabled and 1.55vcore (no vcore mod yet)

I tired RMClock, and got x6 multi, but with no "real" results (only "software" results...). I belive TAM or NewBeetle (whichever of them had this same setup) had a lowered multi for 21s superpi, and I have seen a member at EOCF w/ a lower multi @ 282 mhz FSB, which he stated he achieved through crystal cpuid.

I will have to try Crow's suggestion....I would feel extremely foolish if that's all it was. :slapass:

Hope we can get this cracked....and nice results on the 3.0 ^ k|ngp|n. :)

:edit: NewBeetle has P4C + ct-479, w/ various multis: http://www.xtremesystems.org/forums/...165#post839165 (post #163)....so, it is doable....

:edit edit: In doing some more searching around, my problem probably lies in the fact that I have 400 mhz FSB dothan, which doesn't seem capable of achieving higher FSB, regardless of multiplier. So, hope you guys have better luck.

One problem down, one to go :)
