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 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..

I dont think the problem is my MOBO or RAM can get a P4 2.4 northwood to 3.6GHZ on air...

anyone know what stepping is the best? C0,D0,E0,G1
 
You ever think...maybe that's the limit for that specific CPU? :confused:
 
well maybe but wtf i have seen other D0 cores go up to 4.5, 4.75GHZ !!!! without Ln2 or phase or Pelt..


I do believe that it could be a gimped CPU but i just need to make sure befor i spend another $150-$250 on a E0 core or something
 
I err replied at Anandtech. Do you really need two threads for the exact same question?
 
Has any one heard of a G1 stepping for a 3.2 or 3.4 P4 prescott core?

it looks like it was made just after a E0 stepping
