Take VID4, VID2, VID1 and VID0 ALL to VSS and it should give 1.70-1.71v

Im a little busy with exams and stuff right now, but rest asured I'll do some heavy updating on this thread the upcoming weekend.
Nice info charlie!
charlie take a look at my post... do u suggest anythin?
Try Flashing with AFUDOS and use /NC /PBNC switches.
Ive had the same problem with two or three p4cs too. BIOS flash fixed it in every case.
thanks for the quick reply bro :)
And THEN use EIST to lower teh Vcore in windows... if neccessaryQuote:

Box cooling,default vcore for a start...
Also, taking your running a 740? Is that the max FSB you can hit?
<edit> Didnt see the Mem FSB, NVM </edit>
As he said, its initial testing with stock vcore and heatsink.Quote:

the option is in the same area with cpu speed. set to manual, with my 730@200fsb the mem options are 266,320,400,500,533. it should show up the same if you hit that speed in bios. but if you set it in bios @133 the the only options its seems are 266,333.Quote:

it shows only 266,333. I cant run at 200fsb cause i cant change the multi.
@sharp bro i run it again and it shows 29,325 @ 2428
Thx :up:
With the wire mod (1.55v) you can't boot up at 14 x 200??Quote:

Hey guys,
What would be the best mobo for the CT-479? Goals is to being able to change vcore, vdimm to 2,8 is enough, and fsb of course, also agp/pci lock.
I would like the mobo being able to reach 250 fsb. Wich mobo and bios would be the best for my demands?
Thanks
Highest reachable vcore from bios on non-modded board, is with the P4P800 SE bios 1009. It gives you ->1.6vore from bios.
The 1.55vcore uwire mod is rather easy though.
For pure performance my guess is the P4C800, for easy 24/7 air use my guess is the P4P800 SE.
Haven't got mine yet though (RMA) :)
Doesn't have dual channel, so that's no option.
I'm looking at the normal P4P800 with the bios from the E version, that will give me vcore adjust etc. But in the first post it says that it has difficulties getting above 170...this true?
what do you mean doesnt have dual channel. both P4C800 and P4P800-se have dual channel. Make sure you looking up the right boards.Quote:

Anyone care to explain ? What is CPC ? Where is the tweaker ? My dothan can only boot at 173 MHZ, any way to lock the agp/pci ? Using clockgen, the maximum fsb is 194 no matter which multi I use (even 6x) so I suspect the agp/pci does NOT lock.
Any help will be appreciated !
Thanks :)
May be is gonna be nice , if you tell us what MoBo you have , which model Dothan you have , nobody here is fortune-teller...Quote:

May have been a mistake to get 760, with 15 multi... you need to boot at 201fsb to lock the agp/pci and you can use software once in windows to enable performance memory mode, change multipliers, change fsb and adjust memory timing.Quote:

Thank's ! :)

Works absolutly stable. V-Core on CPU-Z is not korrekt, Speedfan shows real V-Core.
nice ,, :d
@TigersClaw
That's very nice, I am also planning to use P4GD1+ct479+PM740. I just hope the processor will boot with 200fsb to windows. Once in windows it should be possible to lower the multi with EIST if things are not stable.
Is it possible to adjust fan speeds with the Speedfan on the P4GD1?
(warning: I am from Finland so there could be some typos...)
No, Speedfan can not adjust fan speeds on P4GD1.Quote:

Hoping to boot into windows at 201fsb, (2814mHz) at 1.55v on AIR...
OTOH, I have -65C of cooling to help her out ;)

HA, the -65C should do it. Let me know how the air goes. I should have a pelt up and running on it in few days to help me out ;)Quote:

Something is up here with the pin mods. Looks like its no coincidence that everyone is at 1.55v. I first did the pin mod for 1.596v, and I got a flat 1.55v, never drooped under load or nothin. Then went ahead and pin modded for 1.706 to see what that'd do. Again, a flat 1.55v. It seems like the mobo is stopping the startup voltage short at 1.55v for some odd reason, even though the VID is set for 1.6v and beyond... :shrug:
Does the P4C800-E Deluxe have any trouble with vcore or vdimm? Someone I know can perform a mod for me if it would be nescesary.
What would this board need to perform good?
All you guys with satisfactorily running Dothan rigs, could you post some details on your rigs along with descriptions of your setup procedure?
Would be the bomb! :D
Board? (mods / no mods?)
Bios? (flash method)
CPU?
Bios boot settings?
Windows overclocking actions?
Tools used?
Please add results as well - 1M and 3d01...
Then I'll start condensing actual OC results, to give people a better idea of what setups to go for. Would be nice with a more uniform impression of the average Dothan Powah! :)
P4C800-E Deluxe BIOS 1021
Dothan 730 C0 Sonoma
217x12 BIOS boot, max aggressive timings
CPUMSR used to reduce multiplier, Clockgen used to increase FSB
End result 2680-2740MHz(11x243-249)
VCore 1.55v, VDimm 3.3v

nice results!!Quote:

Thanks bro. I'm sure the Dry Ice Jedi won't have trouble putting it to shame. :p Still feel this proc is a dog, I've seen B1's do better.Quote:

I dunno how it'll respond to higher vcores than 1.55v, but like I said earlier, the board won't allow it with simply pin mods. If you want to try more, you'd have to vcore mod. Probably would help on phase change or above. VDimm mod is a must if you're using BH5/UTT (best choice for this platform). Even below 230 2.85v doesn't cut it for the max aggressive timings.Quote:

Kamerat's setup:
P4GD1, BIOS 1005, VCORE and chipset voltage modded
Pentium M 730, Dothan C0
229x12 in BIOS while booting, PCI-E @ 225MHz
EIST to reduce multiplier, ClockGen to increase FSB
Using SLK900U:
Stable @ 2750MHz (250x11) 1,65-1,7V
Benchable up to 2800MHz 1,75-1,8V
Super PI
3DMark 2001
Using Prometeia Mach II R404a
Benchable up to 3100MHz 1,75-1,8V (11x282 3-2-2-4 3,7V with OCZ EB, 12x258 2-2-2-4 3,7V with BH-5, PCI-E @ 235MHz, chipset voltage 2,0V)
Super PI
3DMark 2001, X800 XT clocked a bit
P4GD1, BIOS 1005
Celeron M 350, Dothan B1
175x13 is maximum regardless of VCORE, managed 180x13 in the unsupported Asus P4S800-MX
It seems like voltage is the key here. I'd better get down to doing the vcore mod then. Wouldn't have expected 90nm mobile procs to need 1.7v on air to shine.
All results in this thread added.
Im going to strap my 7700Cu on my baby. Just need those Vapo poles :rolleyes:
Interesting, but the Japanese guys running like 3400mHz++ are all like 1.65-1.70 right??Quote:

Im not much of an engineer, and I have massive respect for the bare naked core. Probably not many spare Vapo brackets laying around.
We need some kind of easy solution for all those 24/7 air users - I'll start searching around :)
Maybe a simple fan adapter might be the easiest. Definately not the most optimal, but easy indeed...
Found some nice ones!

Im gonna try it out when i get my board.
You are running at 1.8vcore? If so, how are you doing that? :confused: :confused: :confused:

Ok, this is really, really, really pissing me off.
SuperPI 1M at 2745. SuperPI 32M at 2672MHz. Prime95 for gods sake at 2620 for 10 hours.
3DMark won't even run at 2650?? WTF is going on here? I got some really high lobby and CH scores but it always exits to windows here and there, can never get a complete run. I thought if it superpied at 2745, 2700 should be a breeze for 3d, but it just isn't doing it.
Let's see... my SuperPI time... 1M ERR! 32M ERR!Quote:

Things are looking good though Guat. It's nice to see this amount of input flowing through this thread. Keep it up guys! (and gals if there are any)
