Is 450 P3 possible to overclock?

[MuLanZ]

I am currently running a p3 450 on an ASUS P2B board. Is it possible to overclock my p3 up?? If it is possible would it be recommended? And to what speed would be recommended? Would i change the bus speed or the multiplier speed. Is it even possible? Would I need a cooling system or would the heatsink, cpu cooling fan + chasis fan be sufficient? THanks...

just try it with its own cooling, the clock is locked, but you can change the FSB, go for 124, or 133... dont up the voltage more then .3v (2.3V) good luck!

ya they clock great,you might have to tweek the voltage alittle

P-3 450@133 FBS for 600mhz 2.3v
256 mb pc 133 mem (no name stuff )
Abit BE6-II mb
Arctic circle w\backing plate and fan
heatsinks on cache chips
Voodoo 3 3000 @180 mhz
SBLive
full tower with lots of air flow through the case
" now now ,don't clock angry. "

Cool, so how do you change the voltage? And is it dangerous?

Gotta love the search tool.

man, Geekish Thoughts has it down! don't know much about your asus board, but i'm sure there are people in here who do,and will be happy to help. i know alot of people don't like this abit board i've got,(BE6II),but the bios settings (lots!)were one of the things that sold me on it.
-make one change at a time,at least at first he he
-keep track of what you did so you can put it back
-and try diff combinations of settings
have fun

Mulan,

The P3 450, in general, can run 558MHz at default voltage and factory heatsink/fan. By the way that is 4.5x124MHz FSB @ 2.0v.

I had on running like that for quite some time. It was completely stable! Good luck.

Thanks a lot guys!

I think you guys are assuming he has a Coppermine. If he has a Katmai he'll be lucky to hit 500, I'd bet.

In any event, check Tom's P3 Performance Guide:

Not at all. The Katmai 450 P3 does 525-600 reliably. It's a good overclocker. (Non-coppermine) Plus, I don't think they even made a 450 Coppermine.

was under the impresion that copermines don't start til 500mhz,but anywhoo i was talking about a poor old katami core. mine will post at 612, boot at 607,and totally stable at 600

Ulysses,

Please, bet me! I don't want to offend you, but you don't know anything about overclocking the katmai, do you? I thought everyone knew the Katmai processors run AT LEAST 500MHz with 620MHz being the upper limit (with air cooling). I remember when the Celeron 300A was the best overclocking CPU to have, then was the P3 450, now its any of the slower end coppermines (550, 600, 650). I used to have the P3 450@558MHz default voltage and stock fan/heatsink and now I have the P3 650@806MHz default voltage and stock fan/heatsink.

The P2B has no provision for altering the Core Voltage value. Neither jumpers nor settings in the Bios affect Vcc. Using a PII or Celeron on this mobo, you can selectively prevent combinations of the VID pins from contacting their opposite "lands" in the Slot 1 socket. This is the only way to adjust Core Voltage. I dunno if this holds true with PIII Katmai processors.

I overclocked my old P3 450 to 700. I had a Alpha/peltier setup on it.

well mine isnt a coppermine and ive had mine at 600 for some time now with a tennmax stf cooler ,wished i could get the voltage down a bit from default would help cooling out a little,that is my other board than below p3-450 is in a p3bf board with a tnt2 ultra ,if you look at it it looks like a coppermine design but its not mine is the SL35D variety
