Just been doing an upgrade for a mate and it includes a 2.8Ghz Northwood pentium 4 processor.

I now have it at 14 x 220 and it maxes out at 47 degrees after an hour of occt and prime95.

Anybody know the safe and advisiable 24/7 max temp for this cpu?

Cheers
 
They throttle at about 90C - download Throttlewatch and clock as hard as you like, so long as it doesn't throttle, it's fine.
 
280-300x14 is realistic if you have the cooling. There are, as always, good and bad steppings though.
 
They were well known for being good clockers.

But the fact that they dimmed your house lights when under load kinda spoilt it.

Fair enough. On standard stock cpu cooler so I guess I won;t be going that high.

On stock cooler, where should I be aiming for? 3.2 - 3.4 Ghz?
 
This is stretching my memory a while back but generally anything sub 80c is quite alright on a Northwood. I believe most would hit their max at around 3.5GHz with a couple of exceptions such as the binned M0/D1 Extreme Editions that'd make it past 3.7GHz. Also, I'm quite sure it were the Northwoods that were susceptible to failure by excessive voltages and considering the potential age of the chip, I wouldn't go way above it's rated 1.525V (I think it is?). In any case, 47c is just fine. I have a 4 year old Northwood C 3.0GHz sitting in an SFF box since 2005 and it's been loading around 70c without any trouble.

I'd be aiming for around 3.4-3.6GHz but of course this will be dependant on the RAM you're using.

:eek: 4.2Ghz with good cooling????? I didn't think they were that good :confused:

From what I remember the 2.4Ghz were the best overclockers, on good air cooling they would go to around 250/260fsb, 300fsb on phase maybe. I would be happy with 3.2/3.4 24/7 from a 2.8 chip.

I seem to recall 65c was the load temp to keep under, so if 47c is correct you're fine.
 
A 30 capper 3.2Ghz Gallatin cored 'failed' extreme edition is what gave me 4.13Ghz on stock volts and only an XP120 cooling it :D

There weren't many that did over 3.7 without major Vbumps. i was happy with my 3.0 30 capper hitting 3.92, and 3.75Ghz stable :D.
 
I had a 2.8GHz Northwood M0 that did 3.5GHz on stock volts, was the first decent chip I had, previous 2.6GHz M0 just hit 3.3Ghz with a whack of extra voltage.
