Overclocking

[KingTom]

I have an AOpen Intel PIII AGP ATX motherboard clocked at 450 MHz manufatcured in August 1999.
Can anybody tell me how & how much i could/should overclock this?

Depends on what kind of cooling you have and what the processor is capable. It can vary a lot when and where it was manufactured. I had a PII-333 Mhz that I clocked to 500 Mhz a while ago, and it worked out pretty good with regular fan + heatsink.

Suggestion: Check out www.overclockers.com

I wouldn't recommend overclocking as a long term solution though, I've heard it causes all sorts of problems

thanks

He's got a 450 Mhz, I doubt he's in it for the long run.

"ive heard it causes all sorts of problems" <-- theres an expert for ya seriously, if you dont go crazy then overclockin can niceley give you a 20-30% performance boost, but if youre after something significant then id SERIOUSLY upgrade that 450

As long as you know what you are doing you shouldn't run into any problems, if you remeber the good old days when Celly's could do overclocks in the 40 - 50 % range with reasonble cooling of course, i.e a peltier sandwich... But if your motherboard supports it you should be able to raise the FSB(FrontSideBus) from 66 to 100 or from 100 to 133. Increase the FSB in small steps and check your motherboard manual for PCI and AGP dividers. A FSB setting which doesn't split even will make your system unstable. And as Martin said, go to overclockers.com and rad up on the subject.

I tried overclocking my PII 300 before and got it to 350MHZ, but then win2k stopped booting So then i did 333MHZ then Unreal stopped working! So i went back to the good old 300MHZ

Anyway, to do it you can either change the FSB from what it is now to one higher e.g. 66->100->133 but make sure your ram is capable of the higher speed.
Also you can change the multiplier of the FSB.

My multiplier was on the motherboard and FSB in the bios, it's different for every motherboard.

I've been running my Duron 800@1070 for a few months now, basically 24/7. No probs

Slougi, I seriously recommend not running it 24/7. I had a friend talk to me just last week complaining about his processor melting his socket because the headsink couldn't move the heat fast enough. He was overclocking. I also got a call from a gentleman who thought overclocking was a solution who also couldn't move heat fast enough. His socket didn't melt, but the processor died. It's is a long term solution. Just not a safe one if you value your CPU. I ran a Celeron 300A -> 450Mhz for 2 years. It was semi-unstable, but the CPU was never ruined. I guess you are just taking a chance.
