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 outOriginally Posted by charlie
I get my 750 today, so we'll soon know
Hoping to boot into windows at 201fsb, (2814mHz) at 1.55v on AIR...
OTOH, I have -65C of cooling to help her out

Well my 730 struggles to do even 2.7 with very cold air.
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...
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!
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

Where can you find a P4GD1? There's nothing on froogle or ebay.
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.
Btw just for the record, DRAM Latency Parameter 11 in the Tweaker is what's enabled if you boot in at 200 1:1, but you have no PCI/AGP lock then. At 201 and above, it's at 01. 11 takes off nearly 10MHz but in the long run seems worth it.
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.
Excellent!!!! Nice result and exactly what I had in mind...P4C800-E Deluxe BIOS 1021

With more of those, things'll start get clearer
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.

Interesting, but the Japanese guys running like 3400mHz++ are all like 1.65-1.70 right??

How about the Zalman brackets flipped upside down??All results in this thread added.

Tried that. They're too high
One simply need brackets that are totally straight...
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...

Im gonna try it out when i get my board.
You are running at 1.8vcore? If so, how are you doing that?
<----- REST IN PEACE, KIT. 1993-2007.
do you have to disassemble the fan and flip over the brackets under the fan blades??? I don't read German

Think they are as low as 1,6-1,65V. It's not much i gain in speed between 1,7-1,8V, but i need to fine tune to get the last MHz in Super PI.

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!
At least you have your setup going! Still waiting on a new CT-479 (call me an eeediot!) and my OCZ VX. Looks like I won't be able to play until next week considering I'll be out of town Sunday through possibly Thursday. Booo!
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)
