P4 2.6C @ 2800 (wont reach over 3.125ghz no matter what VCore)
1gb Dual channel TwinMos DDR400 @ 433mhz CL2.5-3-3-6
Albatron PX865PE Pro motherboard
Nvidia 6600GT AGP
Audigy Sound
2xSeagate 80gb IDE RAID0

Firstly my 2.6c wont budge past 3.125ghz - poor batch, now im looking at buying a brand new intel P4 prescott 3.0, 3.2 or 3.4ghz to overclock beyond the magical 4ghz, how far would stock air cooling go before i get a better cooler? and then how far would it overclock? and would i need to cool my vcore regulators on the motherboard with ram sinks? or would it even allow my with my current board?

i have tried everything - EVEN 1.7v, memory set at 2.8v, CL3 at '266' ratio (even tho at the '333' ratio it will run about 384mhz each), i can do 3.25ghz but prime95 wont pass after about 2 minutes, mind you - its with the stock HSF and cheap generic thermal paste on a mirror finish HSF base, would a better cooler do any miracles? i live in australia - even winter when it keeps its temps low it still dont work... it does state ~50ºc in the bios aswell... too much for mine in the bios (after 5min or more)?

wow your using a prescott with the stock HSF. I guess its becuase low clock speed. How hot does that thing get?

Heat management was a huge concern with the older Prescotts. I wouldn't OC one of them without water cooling. Are you getting one of the newer CPUs (600 series I think)? Mozzartusm is the best person on these boards to answer this question...

Hmm, I'd go out and find a known good overclocking Northwood. I think one of our popular forum members was selling one, you might get a good warranty.

Thats odd, my northwood is doing 3.25 24/7 for the past year and a half! And it'll reach 3.4 no sweat, id stick with northwood for OCing exept if you plan to go liquid...

Asus P4P800DX, P4C 2.6ghz@3.25ghz, 2X512 OCZ PC4000 3-4-4-8, MSI 6800Ultra stock, 2X30gig Raid0

I think the SL6WJ (or is it JW?) revision of the northwood C's were sposed to be very good overclockers.

i got my p4 2.6c (northwood) constantly at 3.25 on stock cooling and when i had watercooling i could get it to around 3.6 stable. your motherboard might be holding you back not the cpu.

The best P4 for overclocking is the SanDiego core! ;)
