Hi ,my name is Jimmy.
I have order a "Intel Pentium 4 3.20 GHz / 1 mb cach 800 Northwood / 478pin" Cpu.

Is this a Cpu to overclock?.
My P4 northwood 3.06 run's in 3450 ghz now ,but i think the new cpu can go higher.
And it has 200 mzh on the Fsb.

Anyone know this cpu's abilitys?. 3.20 Ghz P4?

Best regards Jimmy
 
Hi Jimmy

First thing most will notice about the details you have given us is that the P4's with 1mb cache were Prescott's not northwoods so a little more info would be good mainly the numbers on the heat spreader especialy the code that will start more than likely with "SL"

:)
 
Northwoods are usually very good clockers, I used to have a 1.8 ghz one and managed to **** it up to 2.6 ghz. You should reach 4 ghz easily (possibly a little more) having said that bear in mind that no two cpus are the same so make sure you are careful and check the cpu is not overheating

Had to have a good rofl at this post ...
 
Not all processors clock the same amounts like that. If a 2.8 hits 3.5Ghz, doesnt mean a 3.2 will hit 3.9Ghz. Chances are itll top out around 3.6-3.7Ghz. My northy is a '30capper' and tops out stable at around the 3.75Ghz mark.
 
i think that model is a 'prescott' core so 4Ghz should be achievable with good air cooling, anymore would proberbly be optamistic considering prescotts get very hot, would have went with the 'cedar mill' core to be honest, 65nm and higher clocking

Lol, I don't think they even made a 1.8Ghz Northwood did they?

Yes. The first Northwood-A's were launched as 1.6, 1.8 and 2.0GHz parts. I'm typing this on a 1.8A :p

Fair enough, what was funny , my overclocking a 1.8 ghz cpu or my unfortunate spelling mistake

I think the part where you said he'll reach 4Ghz easily... that would require an FSB of 250MHz, which is no mean feat for most motherboards. Cooling issues may also be a problem as it's like you'll have to stick extra volts through it to get a decent overclock.

On air, I would predict that the average 3.2Ghz Prescott would get to 3.7Ghz or so. 4Ghz would be very good going, and I'd be very pleased with such a clock!
 
He's was being a little sarcastic with your optimism to reach 4Ghz so easy on air.

Nortwood wise there was very few chips which ever reached 4.0Ghz on air. Some of the later C steppings got near there, but it was few and far between.

Anyways besides the point you have Prescott. Decent air cooling will see you most of the way to 4Ghz depending on revision.
 
I have a 3.4GHz Northwood, D1 revision on an Abit IC7-MAX3. Even with very good ram (OCZ PC3200 Plat rev2) I have never been able to get it above 3.75GHz in a stable OC on air. It seems that it is the architecture of the Northwood that limits it to between 3.75-3.8GHz.

I have a 3.2GHz Prescott on an Asus P4C800, but have never really tried to OC it much, so can't really comment on what the highest OC of it might be. :)
 
i CAN comment on this chip ;) finally im put to use! righto, i got a 3.2ghz P4 socket 478 running on a P4-P800 X asus board and with watercooling i got the chip to 4.31ghz! thats stable and on 1.5gb of pure VALUE crucial RAM!!

however during the warm weather i keep it down at 3.8ghz cause otherwise my room starts getting warm! i would say on air 3.8ghz is a reasonable overclock, but with water my chip hit really night overclocks! dont knock it! :rolleyes:

EDIT: its a prescott chip that i have

Thank you booner
 
It may be possible to get good speeds out of it on a water cooled rig, but it wont go so far on air, without getting extremely hot. Socket 478 prescotts are notorious for their heat generation. Considerably hotter than their socket 775 counterparts.

On the intel 'stock' cooler, they often hit 60 degrees idle and 80+ under load and thats before you even start overclocking. Although with an after market cooler, its not to hard to get it down to 50 idle, and 70 load (Changed cooler on a friends prescott, and got a 10 degree temperature drop over the standard intel cooler).

Assuming you have enough cooling to prevent meltdown, the chip itself could well hit 4Ghz+, but you could still find the motherboard, and/or ram maxing out before then anyway. You dont mention what MB you have.

I fitted a Thermalright XP90 + Panaflo fan to my 3.2GHz Prescott (socket 478), which brought the Idle temp down from around 48-50 C to 38 C, and Full Load temp down from 60-62 C to 47-49 C.

The stock CPU Heatsink/Fan for the Prescott, I think, is pretty useless. :)
