cpu swap problem help

i currently have an older p4 2.4ghz hooked up to it now, and PC Wizard says my processor temp is 18c that cant be right...???

Absolutely not - at least not air-cooled. Try other Temp programs; SpeedFan and Everest are the most popular.

in bios it says cpu temp 39c

WTF?

BIOS will give a very accurate temp reading, but really should be used to to make sure the compound and HSF is installed properly, not to give realistic usage temps. In BIOS, a CPU will run at 100% speed (so even if the CPU supports scaling, it won't while in BIOS), but it's at zero load. Typically, when you do a system build or upgrade a HSF and want to check it out, you'll let it sit in BIOS for a few minutes to make sure everything is kosher. What you want is the Idle temp during Windows.

but it wont load windows, it'll usually shut down right when its done loading
 
It's possible the newer CPU is quirky, but until you isolate all the other causes, it would be too hasty to say at this point. It is possible, however, that your Board doesn't support the CPU. While it may recognize it and load Windows, things might not be right behind the scenes and the Board doesn't fully understand what the CPU is doing.

Socket 478 was a *huge* time for CPU evolution - technology was exploding about mid-way through it's run and newer CPU speeds/architecture were constantly being released (higher clock speeds, HT technology, transistor size).

Edit: actually, I was a bit hasty in typing this - if the CPU were dead, you wouldn't get anything. Changed above to reflect.

GURRRR!

idk what could be the problem...
both board and cpu support 800fsb, HT technology, and p4's...

what is cpu host frequency? on p4 2.4ghz its 133mhz

but on p4 ht 3.2ghz its 200mhz

(set to auto)
 
Early P4's were measured in microns (.13mu, .18mu, etc.), later were nanometers (90nm). If the Celeron is .13mu and the P4 is 90nm, that could help to explain it. If you have the models of the CPUs you can check out Intel's website to get their specs.

pent 4 2.4ghz = .13 micron (sl6pc)

celeron d 2.8ghz = 90nm (sl7nw)

pent4 3.2ghz = 90nm (sl7b8)
