View Full Version : How Good Do The 2.8g P4 Prescott overclock

I am setting up a system for my x and it is a 2.8 prescott and I was wondering how well do they overclock and is the main thing I have to worry about is heat.I am used to AMD and this is the first P4 system I have ever set up.

you cant O/C a Prescott in the UK without a license from your local power grid (joke)

You WILL need some major cooling - why bother when the 3.2's are cheap enough...........

This is not mine it is my x-wife and where she bought it ,she was told it was a 3.2 but it is just a 2.8g ,she can't take it back since she bought it at some flea market ,I guess she lucky it even works,was all prescott's built on the .09 process,The highest I have had it up to was 3.486gig and it seem to run fine and it stayed at 45c while browsing windows,but I brought it back down to 3.213gig just to be on the safer side since it runs around 38c in windows ,had'nt run any games since the onboard graphics sucks bigtime I ran 2001se and got the big score of 2,200.I had never mess with a P4 so I am mainly just playing around with it just to see how good it overclocks.

Hey, are you using CPU-Z to check the rated speed or reading it from the CPU itself? I had a similar incident once where the motherboard not supporting Prescotts dropped the multi to 14 instead of the default 16. I had to increase the FSB to get it to standard speeds.

I had my 2.8Ghz Prescott upto 3.6Ghz for awhile. That was watercooling though. I eventually backed it off to 3.4Ghz for summer and left it there. With air cooling you wont get much futher that 3.2-3.4 Ghz, Prescott just run way to hot.

I use CPU-z to check how it is running and it has a 21 mutipler x 133 FSB ,I have set the memory to 400 and then I overclock the processor to 150.,so that it runs at 3.150gig and the Buss speed is at 600.
