I have a P4C800-E Deluxe
Corsair DDR XMS 4400C2Pt
P4 3.2Ghz D0 prescott
Koolace Exos CPU,GPU,GFX

For some reason my 3.2 D0 wont break 4.16GHZ at all!!! well i can get 4.26GHZ but not in windows
i can run 4.16GHZ 1044Mhz FSB 1:1 in windows all damn week even if i drop the ram to 133Mhz (from 265) it wont boot stable I am able to boot windows and run stable on (1.375V CPU) (2.6V RAM) (1.5V chipset) @ 4GHZ but even if i go 1MHZ past 4.16GHZ it wont boot windows stable i have even pushed it to (1.45V CPU) (2.85V RAM) (1.8V Chipset) it dosnt help....

my temps @ 4.16GHZ are 40c Idle and 45.5c Load CPU, 28c Idle 35 Load Chipset, and my ram is barely warm to the touch.
I am using a Koolance Exos unit W/ 200w CPu block and a 200w Chipset block, I also have a 6800U (490Mhz/1.19Ghz) W/ a NV2-L06 block. the vid card brings the sys temp up by about 2-5c

I dont thing temps are effecting my OC toomuch. is there any way my D0 core is holding me back?

anyone know what stepping is the best? C0,D0,E0,G1

The Prescott 3.2 GHz D0 core sucks. It gets waaayyy too hot even when running at 3.2GHz. 104 Celsius? That's killer, man. Literally, your cpu may be permanently damaged at anything past 100 Celsius for those D0 cores. The D0 core is definately 100% the problem. New CPU? If so exchange with an E0 core if you can...

Aye this is why some people call the Prescott - PresHOT

oops my bad i had the temps in Fahrenheit i went ahead and converted them back to celsius.

there is no way i would be dumb enough to let my cpu hit 104 celsius.


I had a C0 core and i was able to lower the multi to 12 and get an FSB of 1400 and a CPU clock of 3.995 but it would never break 4GHZ!!!
I traded the C0 for the D0 hoping it would have been a better choice.. :p 
but you are saying the E0 core is a much better choice??
ill start looking for an E0 core

Its weird cuz i have seen people have D0 cores on stock air running 4.1GHZ and water cooled to 4.5-4.75 in windows :p

Wait...maybe I missed something. I thought that only Northwoods had a C0 core--Prescotts had them?

OK take a second opinion before following my advice. I'll look into that again and make sure I'm not giving you false leads...

I have a Prescott 3200 E0 core.
Those are excellent overclocks anyway, it could just be the limits of your components combined.
What are you cooling it with?

im using a 200w Koolance CPU block.
I have a 320w Pletier Plate that i used on my 6600GT but i dont think that the drop in temp will help much. i have had the temps down to 20c on the cpu and 17c on the chipset (in idaho u just have to open your window for sub zero temps) but it wouldnt break 4.16GHZ!!!

likely the components... what motherboard are you using? that Prescott should be able to go higher.... I have an E0 myself 8)

I have an ASUS P4C800-E Deluxe

I can get a P4 2.4 northwood to 3.6GHZ on air...
I did a little research and will post a list of 3.2 and 3.4 Prescott cores shortly

I have a 3.2E E0 but for some reason I can't past 3.6ghz... I must be doing something wrong... my sSpec is SL7PN. My friend also has a E0, but his sSpec is different from mine, although we both seem to have the same CPU. His sSpec is SL88K. I'm not even sure what the difference is...lol

Is it because of my mobo? I have a P4P800SE.
