Overclocking a Pentium 3

Post by craigbr »

Could anyone give my info or website addresses about overclocking a 450Mhz Pentium 3 CPU?

Thanks for the help. I'm a rookie you see. I have a fan and a heatsink of my processor, and one intake and one exhaust fan in the case itself. The motherboard is a dell one, as it is a dell PC, all I can find out is that the BIOS is PhoenixBIOS 4.0 Release 6.0??? Don't have a clue what that means.... I have 512Mb RAM PC100 I think.

WElcome :)

basically you only have the front side bus to play with because they are multiplier locked\\

you will need to increase your fsb a little bit at a time, and probably increase your voltage as well -

you can go to the database a http://www.overclockers.com and see what you might expect

you're probably looking at +~75-100 mhz max on that chip - you may need better cooling as well

if you give more details such as mobo,cooling etc, we're happy to help - we've all been there and done that!

The same website the wvjohn gave you a link to also has a good beginers guide to overclocking. Hopefully you mother board supports higher FSB speeds.

Actually, I believe the P3 450s are the best Intel Overclocking CPUs. I've had my P3 450 run rock solid at 600MHz at default voltage with the help of Global Win VOS-32 HSF. When I got my PC166MHz CAS2 memory, I took it all the way up to 675MHz. It probably could go more but both of my motherboards, ASUS P3B-F and ASUS P3V4X had the 150MHz maximum FSB setting.

I wish you luck overclocking your PC with the Dell motherboard. I believe it has the FSB adjustments locked as well so you cannot play with it. Also, if you'd be able to set the FSB, I'd suggest PC133MHz CAS2 memory instead of your current 100MHz as it won't overclock beyond 112MHz and remain stable. Unless you really got some good 100MHz memory, you may be able to run it at 124MHz max. I'd also suggest a better HSF such as the Global Win VOS-32 - it gets the job done. But whatever cooler you decide on, make sure it has its fan/s rated at or above 4200rpm.
