Have i hit a wall?

[dragonslayer45895]

Ok...ive been trying to over clock this computer all night long....but it seems that this happens:

It is perfectly stable at 3.04ghz (original 2.8) FSB: 215 Multi: 14 (locked)
But the highest i can get it too is 220mhz...but its finiky in windows (Even with a voltage bump on the CPU)
At 226mhz it hangs in the bios

Ram is 1:1 with CPU

Heres the Rig in question:

DFI Lanparty Pro 875B mobo
2.8C northwood P4
XP 90 HSF
2 x 512 Crucial Ballistix DDR500 (dual channel)
550w Antec PSU (has very good amps on the 12v rails)

My temps at 3.04Ghz are IDLE: 27C and LOAD: 36 tops with Orthos Torture test
Im guessing its not temps that are the problem

Did i hit a FSB wall with my mobo?

If any of the [H] crew could help me to OC this thing i would like that alot....Im aiming for 3.2Ghz (229 x 14)

Thanks in advance, Harley

she's alreaay at oop speed capin, she caan'[t] take any more!

don't bump the voltage of that northwood to high, at 1.7V many come down with SNDS, thats "sudden northwood death syndrome".

I hope shes not at top speed

As for the voltage...i only bumped it up one notch...i think it was from 1.5 to 1.55

This board could crispy fry the northwood....i think it goes to like 1.8

But...im hoping that somebody could tell me if ive done something.....or havent done something at that

i think intel tried to release a 3.0GHz SKU, and i think its yield was somewhere in the area of 50% (really really bad), so in other words, you are at top speed i think. give the NB voltage a little bit of a bump.

hmmm...i dont think this board has a northbridge voltage minipulator.....im going to restart and check for sure and report back in a few.

Thanks for that idea

EDIT: Nope...no NB voltage modifier...

and the CPU volts can go clear up to 1.95
Ram can go to 2.9....but its already at 2.6 (rated volts....)

EDIT # 2....would i have better luck with a Prescott?
