Asus + CT-479 is the way to go.Quote:

It is a B0 stepping or C0 stepping. If you has an ES chip, these were really good B0's to show 133 was possible and are really 100 mhz chips. You can tell in CPUZ.Quote:

It is the end of the chip. Try booting at 200x10 and CG up from there.
CG up from there :confused:
Don`t undestand CG !
CG = ClockGen
Nanok
Are you booting at 200 or 201? I noticed an ATI video card. You must boot at 201 and make sure you have locked the PCI/AGP to 33/66Mhz.
Oohhh But Clockgen says 33/66 When running fsb 220
I try booting at 201 !
And after rais the fsb with ClockGen ?
Nope that dident help :shrug:
Still won`t extend fsb 220
What multi are you booting with?
If you are use 12 (default) then you are at 12 x 220 = 2640 Mhg .. pretty good.
Try booting with a multi of 9 or 10 x 201 then try ClockGen.
There's a new beta bios for P4C800-E here for dothan you folks might take it for a spin Beta 1024.001
Multipier 10 or 11 don`t it dosent matter !
higher than 220 and its not stabil
And 12*220=2640 is not fine i won`t more :mad:
Lol.
Put in a new Dothan 740 today. A little better overclocker than the last one. That one did 2.8GHz. This one does a little more. Using a Zalman 7700 to cool it with. The RAM will only follow to about 2.8GHz, so I didn't try benching any higher. Think I need a better 2x1GB RAM kit. Here's the results:
Dothan 740 @ 2.95GHz

Ok I see, thanks for the suggestion :)Quote:

Is my pci/agp lock not working ?
13*220 no problem with idle temp on only 30c
you can't boot to high fsbs
also, 6 shouldn't allow high fsbs, 7 should revert to 6, and 8 shouldn't post at all
you got to set 201 FSB, and up it with clockgen
Managed to squeeze a bit more out of my Dothan 1.60Ghz
http://home20.inet.tele.dk/pressure/Dothan2880-2.jpg
It tops here, I can't even make a suicide run at 2900Mhz.
Great job pressure! What kind of cooling are you using and tweaks?
I got my 740 up to 2900 for a windows boot before the adapter blew out yesterday night.
why on my dothan can't use multi <9
Works fine here. Didn't notice any differences though..? Thanks anyways ;)Quote:

I was thinking about selling this chip and go for the P-M 740 but for now 2.88Ghz on a Dothan will do nicely :D
ok here's some strange results. got my 740 a couple of days ago and had ago at clocking it with the stock ct479 cooler....
210x13=2730mhz, super pi 1mb 28.609, 3dmark01 27382
230x12=2760mhz, super pi 1mb 30.xxx, 3dmark01 26xxx
the comparatively low results are due to the fact i only have geil value ram @2.5-3-3-6 :p:
but the timings were the same at both clocks and i think it's little odd that i'm getting worse results with the higher fsb/overall clock speed. :confused:
any ideas? :)
Marc,
Was your ram at 1:1 (400 MHZ setting in the bios for me) or divided? If you set ram to auto and crank the FSB, the bios would read the SPD info and try to keep it within spec or underclock it a tad.
hehe :p:
it was on auto and i assumed it would run 1:1, but it was 3:2..... funny thing is i could have sworn i checked it previously in cpuz but i obviously didn't.... :slapass:
thanks for that. :)
my value ram don't like 230 so i'm just testing now at 225x12.
Can anyone tell me exactly what pins to jumper to get 1.6 volts to my Dothan? I currently have the simple pin mod giving me 1.55 but it drops to 1.52.
p4p800-vm
740 200X13 2600mhz 1.55volts
1gig pqi turbo 2-2-3-5

http://img226.echo.cx/my.php?image=pinmodphoto2zm.jpg
I'm a newbie so I'm not sure what the advantages/disadvantages doing this pinmod has compared to the motherboard vcore mod, but I would like to know. Maybe some of the pros can answer that one :D
Something I just thought of -- you probably have to start with a lower vcore bios setting if you do the pinmod. I'm pretty sure that jumping the pins bypasses the bios settings. I would set it back to the default 1.340v in the bios to start.
It doesn't bypass bios settings. Pull up Intel's Pentium M tech docs. I don't have time to do that now. You'll see that 1.34V (stock speeds has a certain binary code (eg 101001 where each number represetnts the state of a VID pin). Depending on the set voltage, and which you ground, that's where you new voltage will come from.
Eg, if you have 1.196V set in the bios, (100000), and you ground VID5, you will get 000000, which is 1.702V. If you have 1.34V set in the bios and you ground VID5 you will still get 1.34V, if you ground VID4 however you will get 1.6V, etc.

if you can confirm i'll do the mod and report back. i don't want to fry my 730 if this od only meant for the 7x5 cpus.
just tried it but it doesn't do squat. still stuck at 1.55v max.
just ground all the VID pins, you'll get 1.7VQuote:

I'm currently testing in Super pi.. it's 23.014 at the moment, because the 915PL is very slowly.
When the the rams will arrive, i will choose an higher FSB (the P4GPL-X does 290 MHz). The PCIe frequency is set at 140 MHz.

hey guys i just want to know which mobo is the best for oc dothans with pci-e
Did you read that whole thread? I don't think the actual voltage will be readable by CPU-z. I don't know the points to tell you to check with a voltage meter. Maybe give it a shot again and see if it helps the overclock.Quote:

if you do i'll give it another go.
how did you measure your vcore on the laptop?
yes it will be readable.Quote:

What is the voltage set at by default? You may have some power saving things that are changing the voltage.Quote:

So it is
My P4GD1 died yesterday....with the Ct-479 and a Ce M in.
I dind't go over 1.4V as it is said...and the CPU was clocked @ 2.45 with the memory @ 214 (funny RAM ratios) 35 sec SuperPi
anyone knows this problem??
PSU and RAM was knew, board was previously installed with a Prescott..@3.73
(mofsets have suffered...??..Vcore/Prescott@1.55...Watercooled)
Mobo was 7 months and used 3 times a month....
So,........after some tests, the result is that the Mobo is dead...and it's difficult to find some right know......
So i'm planning to replace it??
I need ability to change Vcore and FSB....
and i already own a P4P800......Shoud i try the Ct-479 on this board??
same thing happening here.done the vid mod.flash with different bios.on first boot in bios will have the volts all the way up to 1.9v but seems to revert back to 1.6v.other suggestions?
---------------------------------------------------------------------------
P4P800 SE(no mod yet)
PM750@2845ghz watercool
BFG 6800ultra@450/1.2ghz
2x256mb Corsair PC3500C2@2-2-2-5
2x36gig Raptors
OCZ DDR BOOSTER@3.6volts
OCZ Powerstream 520watts
Any ideas as to why my Sandra's CPU Arithmetic benchmark scores don't increase with FSB/CPU speed?
All Sandra tests were performed with CPU booting at 201x12, then EIST & ClockGen to overclock further. The score seems to hover around the 10400 mark (+/- 50), despite trying 250x10, 260x10 and 270x10.
It's got me puzzled, any ideas?
Unless extreme cooling is used ("Prommie" or LN2) it seems that most people oc'ing Dothan's will reach a certain clock where it is pointless to increase VCore.
Those of you that think it's a problem not to be able to raise the VCore above 1.6.. and uses "ordinary" cooling (including WC) should reconsider.. Just my 2 cents.. :)
found a pic for the vcore and vdroop mods on the p4c.
will the same vcore mod works on p4p with a dothan ? is >1.6v possible ?
http://www.photoi.org/share/upload/1...revdrop_th.jpg
hey guys i just want to know which mobo is the best for oc dothans with pci-e
there is only 1 mobo that supports dothan and has pci-e
Only one way to go; the P4GD1Quote:

At present I use/test a Celeron M 350 (1.3) in this board/rig.
Not particular good OC.. "only" 164x13.. at default VCore (1.275). To increase VCore does not help at all.. it only increases the temperature..
I will get at Pentium M 740 for this board soon and report back..
i thought there is only one, cause there is talk here about only one.
and i need vcore over 1.6v for some extreme cooling, not stock or even water.
i don't there is one man or else it would have been posted already.Quote:

Hi! This is my first post here :)
Here is my dothan
2635Mhx 293 x 9 (3-4-4-8) 1.600v - sPI 27s
it's not very lucky.... :wth:
I ve only vdroop now...I ll try the vcore mod as soon... I use water cooling.
Do you think i can try 1.7v? Only for bench?
correx, which ram are you using, i tried Geil One TCCD, and couldn't get pass 255FSB.
but you have here really bad result, i had my best with air so far, at 220x12 with geil ultra x bh5, 26.641s
I m reading your thr about the vcore max... I m in the same situation...Quote:

win xp sp2, no services tweaks, only crashed explorer, and Pedro&Rocka tweak helps a bit.
What is det difference between Asus P4C800-E Delux rev. 1,02 and the Asus P4C800-E Delux rev 2,0 ?
i bought myself a dothan after reading all this and being very impressed, very happy with it, but i have a few problems.
firstly, it wont boot at anything over 107 fsb, secondly, after adjusting the multi with cpumsr, i can go to 207*12 or 191*13 at 1.425v in bios, but if i want to go anything higher than 2.5, my comp freezes instantly, no mater what voltage.
have i hit the limit for this chip, or are there any settings i can change that i dont know of?
specs:
pentium m 740, p4p800-e bios 1008, 512 mb noname ram, asus 6800GE
i hope you can have some patience with noobs like me

to bad. Is there a bios for p4p800-e that can change multiplier, that way i can boot at 200, so that the agp/pci locks work.

Just of curiousity..
What kind of temps are reported using the "tower"?

No way this cool Dothan has the same full load temp as my P4E@3.5 (in another system). The Zalman (and the socket) is hardly lukewarm during Prime'ing..
@ Raiden Zero : Well, with around 50W of real thermal dissipation of your Dothan running Prime almost at 3GHz, the temps from OnDie Cpu diode around 54°C are normal ! Maybe for your ex-P4 the temps were too low instead .. :-)
When posting your OC results, can you guys please specify if the CPU is retail or OEM.
I have the impression that the chips that are able to reach +2.8Ghz are mostly retail, but I might be wrong.
Thx. ;)
Jesus christ that's the best I've ever seen.. :slobber: *jealus* Do you know how it clocked with the original heatsink? Do you think mounting of that Sonic Tower cooler is the reason for that high clock? Is that the best aircooler for Dothans? The Big Typhoon needs the four screw holes, but the Zalman 9500led might fit.. But maby the Sonic Tower is better? How would watercooling compare to all that?Quote:

Good aircooling.. is still aircooling.. and to get the last 100's of Mhz.. LN2 and other "extremes" is necessary.. togheter with a very..very..high VCore..
Be prepared to burn/chip "a few" Dothans on the way.. (the best "clockers" over here i Norway knows all about that).. :)
People here at xtremesystems know that too ;)Quote:

We all want to tweak the last little bit out of our systems right ;) So when I saw Raiden Zero's results with the Sonic Tower heatsink I also saw a way I could potentially increase my own results.. Unless you know better, this should be in your own best interest also so I suggest you pay attention ;)
I will let you know if better air cooling gives more overclock or not.I have a modded SI-97 on my 760, it runs 44C prime95 at 2875mhz and 1.55Vcore.Thats its max, 1.6Vcore makes no diff and it will boot into windows at that speed.
I am going to mount my 10 heatpipe xp-120(2 xps soldered together) and see if it makes any diff in the overclock.I will also try the stock cooler.
Wow fordf250 :) And you already have a good cooler installed :)
Thanks for doing all that - Looking forward to your results! :toast:
Yes I agree.. in principal. :)Quote:

The more experienced "clockers" here may have tested "a few dozens" chips to see a pattern.. personally I do not have the funds (or time) to do that.
Just to "prove" my point:
I was able to bench my 730 using stock cooler resting on the socket/chip at 75 C @ 1.55 VCore at the same clock (210x12) as using my properly mounted Bitspower Silent Storm at 42 C (same clock/VCore)..
"Upping" the FSB to 213-215x200 (or 255-258x10) resulted in lockups/instant shutdown. Increasing the VCore had no effect.
When this is said.. I did see pretty much the same "pattern" with my last A64 Venice.. It runs from 1.8Ghz to 2.65Ghz on pretty much stock VCore (1.4 to 1.45).. It will run stable at 2.7Ghz at 1.50, but anything over that is pointless (24/7).. This is with Thermalright XP90-cu.. max load@32C (Yes.. the Bios for K8N Neo2 has "issues" regarding temps).. :)
Not used to this "strange" behaviour with "Barton's", XP-M's and P4-NW's.. :confused:
