Need Help In Overclocking A P-II

[TechTalkie]

i have a p-2 450mhz on a luckytech p811a mobo(intel 810e chipset)
in bios i have the options 100,103,124....
i want to run the processor at a faster speed, but i can push it to just 464mhz(103*4.5)
when i put it to 124, either it shows the overclocked speed and hangs or beeps and hangs with a blank screen
this could be a fault in either the hdd, ram or some ide device...
i cannot find the voltage adjustment anywhere in the bios....nor on the board
how i can i boot up with fsb set at 124? is it possible?

Also, i have pc-100 128MB SDRAM,Seagate Medallist HDD 10gb HDD, Samsung 52x cd-drive and 250W SMPS

The number of Pentium II 450MHz processors that could run at 558MHz are extremely small.
I've never even seen one that could do it, though I've heard of a couple.

Your most definitely not going to be able to do it at default voltage.

A major limiting factor in overclocking PII's was the off-die half speed L2 cache. The L2 cache on most PII 450's was 8ns rated, and good for 225MHz. It's awfully unlikely that the cache would be able to handle the 274MHz speed you'd be forcing it to if you tried to overclock the processor to 558MHz on the 124MHz FSB.

Not to mention on a 124MHz FSB your probably still using a 1/3 PCI divider which would put the PCI bus at a very unfriendly 41.3MHz
