Dothan overclocking thread

[NoAffinity]

Can't you adjust the Vcore in bios?

Not on the P4C800. I think the P4P800se is the only one that allow BIOS vcore adjustment.

[micdoc]

what about Vcore mod for P4C800E Deluxe?
you can adjust Vcore ....on fly ! I don't know if you can adjust vcore on fly using CT-479 !?

[cirthix]

how well does tccd work on a p4p800se with a ct479 and a midrange dothan/celeron m (1.7-1.5)?

[bcn]

1. does anyone have any beta bios with multi and vcore ajustments in BIOS for P4C?
2. Does anyone know any software to ajust FSB and/or Vcore on alviso board, like clockgen?
3. WHERE to buy a CT-479?

[kristos]

afaik, asus plans to support the
P4GD1 in the future, maybe there are already beta biosses for it. best check the german asus ftp for latest biosses

Well it's here, P4GD1 now officially supports the P-M adapter


1. Fix Some FSB400 NMD CPU can not boot.
2. Support Mobile CPU CT-479.
3. Remove N.O.S Item while using Mobile CPU.

Anyone knows if you can succesfully sit OCZ DDR -Booster on that P4GD1-board?
I know that the Booster works on P4P and P4C for sure. PCI-E, ICH6, and HiDef-audio sounds quite appealing though...

There also seems to be a .006 beta bios for P4GD1-board: http://www.asuscom.de/pub/ASUS/mb/so...1/1005-006.zip

...no clue but hopefully some nice multiplier and vcore options included

I got a 31sec super PI at 2.4gh'z,havent even started tuneing it yet for the customer.but as it stand's that's 1 bad cpu,even let my boy's fx-55 take a swing at it he failed.

First test w/ the adapter and P4C800-E => Celeron 1.3GHz @ 2.12GHz (1.24V) => SPi1M 37sec (almost 36 ). ram @ around 203MHz 2-2-2-5.

a celeron @ 2ghz is beating my p4 @ 3,3ghz

[alpha0ne]

a celeron @ 2ghz is beating my p4 @ 3,3ghz

it certainly is a different and hilarious way of looking at it , spanked by a celery

[lktuio]

Got exactly similar system like yours. Have you tried higher vcore using u wire mod ? I wonder whats the max vcore and fsb for this celeron (13 multiplier is the lowest one for normal celeron M).

And whats your s stepping for your cpu ? Is it the older dothan (350) or newer one (J suffix) ?

Thank's !

Very interested in your results macci. I have the same processor...made it too 2.25GHZ at the same voltage. Wouldn't run faster at any voltage. At 1.55 V (in bios) something died. I almost hope it's the cpu since I was going to buy a 730 anyway...
Pls. keep us informed how the OC'ing of this cpu goes.

[bcn]

hey guys, where could I get that adapter?

[Venom21]

I saw some Dothans with 478pin.. whats going on in here

http://www.cpu-world.com/sspec/SL/SL7EN.html

and also in intel website:

http://processorfinder.intel.com/scr...ALL&CorSpd=ALL
http://processorfinder.intel.com/scr...sp?sspec=sl7en

look at the 740..

It means that i can put a 478 dothan into a P4P800SE Bios updated?

thanks,

[DrJay]

It is not pin compatible with s478, even though it has 478 pins. IIRC, Intel calls it s479 to differentiate the P-M socket and limit confusion on the issue.

so why in some of them marked as 478 and the other 479?

like in here:

http://processorfinder.intel.com/scr...ALL&CorSpd=ALL

http://processorfinder.intel.com/scr...ALL&CorSpd=ALL


there is one model for 740 533 478 and one 740 533 479?

and sorry again for my annoying questions :|

[kristos]

I'm trying to get the same question aswered but no luck so far

Haven't tried it for more than 5mins so far =)
So everything is very stock. I'll vmod an old P4C800 (flashed today w/ latest P4C800-E BIOS) for the celery for higher Vcore and FSB. Its 350 without J. Costs around 85€. I think its a very fun chip

[Mathias-K]

That's quite a bang for the buck, it seems

If that adaptor would only make it to Denmark.. :/

[DrJay]

Costs around 85€. I think its a very fun chip

Goes for about $90 in USD, for both 350 and 350j.

It seems that Dothan C0 stepping likes even less voltage than old B1 stepping did. This 730 (1.6GHz) chip maxes out at 2.52GHz, no difference between 1.4V and 1.6V.

28 seconds in SuperPI 1M calculation for 2.5GHz (250x10) is pretty fast, if you ask me
(Validated)

The best time I have achived with those speeds was 27.787sec, but the system rebooted when I inserted my USB stick (?)...

Good ol´ P4C800-E DLX never lets me down, and these things can hit reasonable high fsb with 1:1 divider and 2-2-2-5 settings
SuperPI 1M @ 273FSB 1:1 2-2-2-5-4-I-64µs
(Validated)

My 760 (2.0GHz) chip can hit 2.65GHz with stock cooling (Asus) and voltage.
Even it can hit higher speeds, the chip is only good for phase or LN2 runs, because it´s high stock multiplier (15x).

Because the multiplier cannot be changed (yet) from bios, and the board can´t run at high fsb´s when booted with under 200FSB, the chip is pretty much unusable

When the multiplier support will be added to bios, the chip will probably hit 2.8GHz - 2.9GHz speeds with decent voltages and this copper Dothan heatsink (by Akiba)

[kristos]

maybe this can help you out:

Re-flashed 1021 w/ the latest version of afudos, then reflashed with dothan installed. Dothan is still locked in bios, but not in software. Crystal cpuid works great for changing multis in windows. Setfsb works very well for changing clocks in windows too. To get 1:1, 166fsb set from bios was needed along with auto setting on ram. 200fsb set from bios makes 400 divider become available in dram settings. Overclocking went smooth once it got locked into 1:1.
I wish I had more time to spend with it this weekend
Overall impression is its very fast and feels just like fx55 on desktop. I was able to install win2k3 at 166x15 without a hitch. Nearly 600mhz overclock benching on air with def vcore is nice too.
I have some other p4p boards that clock better here that I want to try it on. Only p4p800se is supported though atm.

his topic is just a few threads down the line (still high up on first page)

[leejsmith]

I had tiome to play with my 1.6 dothan today.

p4p800-vm with bios 1016
400fsb dothan 1.6 with ct-479 jumpes set to 533fsb
u-wire vcore mod on ct-479 givs 1.5vcore
2x256mb corsair xms3500 bh5 ram
cascade water cooler with hydor l30 pump and heater core rad.
winfast fx5900 le vid card.

software used
clockgen
i865 tweaker
cpuz
cpumsr for vcore and multiplier in windows
superpi
3dmark01 se

i made some little brackets to mount the cascade into the normal p4 mount not sure how much pressure is on the core but temps are a lot better than the asus cooler which went upto the 60's when i set 1.5vcore with the cascade they never go above 44C at load max oc.

this is the best superpi 1m time.



the max fsb i can get on the cpu is 167 any higher no mater what multi / vcore is used and it resets or locks up i think this is the ct-479 not the cpu.
i tested at ram 1:1 with faster timings but at 5:4 with 2.5-3-2-6 gave me the best time. The ram is held back my the p4p800-vm vdd settings of only 2.65v and i think the board is also maxed at about 2.7 as i tested a ocz ddr booster and at 2.8v the fans started to spin faster and then the board died lucky i had 2.

3dmark 01 se score at 133fsbx16



and at 160 fsb



this is about 300 points below my p4 2.8c running at 3.6ghz with a 6600gt running at 600/1200

if i remember the score on the p4 with the fx5900 was about 15000 in 3d01 so thats a good score with the dothan.

Next think to try is running the p4p800-vm bios on a p4p800 with the ddr booster at 2-2-2-5.

[GoriLLakoS]

cause the thread is huge and i don't have enough coffee to read it all.....can someone tell me if i have to look for a specific stepping about dothans? :p

Shoot for any Sonoma grade P-Ms; they clock better than their Carmel counterparts.
