Overclocking a Pentium 3?

[Dough1397]

well i have two comps both are p3 ones a dell slot type of processor 550 mhz (5.5x100) others a 733 (5.5x133) its a custom computer (w/e you wanna call it, its not dell or hp or ibm)

so i was wondering if there was a way to oc the 550 cause i would like to squeeze some performance out of it... the dell bios seems very limiting as it has no control over anything, if you need more info tell me i will gladly post it

and for the pentium 3 733, it usually runs at no hgiher than 40 (summer hot day no ac full load for 3 hours)
its 5.5x133, so the only way would to be to up the fsb, my mobo is an AOPEN AX34-U i can take the fsb up to 150, is this recommendable? i tried it and it ran for ten minutes but then turned it back down cause i didnt cause any harm to my system. Its on stock cooling, and if i up the fsb to 150mhz how would i get the ram to function at pc150 from pc133? i havent found any settings... any suggestions would be appreciated...

You would need a board capable of something like that like an Abit BH6 or something older. Best I ever got my 550 on air cooling was 5.5 x 120 for a 660.

I don't think those generation mobos have AGP/PCI lock. So, even if the CPU is capable for higher clock, your bottleneck will be AGP/PCI clock. You can try, but you will more likely end up by killing your AGP/PCI hardwares, such as HDD and VGA.

Well, I would't try if you ask me. I don't want to bet my hardwares for a little performance boost..

i've oc'd the 733 to 825 (5.5x150) using the p3v4x, regular crucial pc133 cl2 ram, and stock cooling, so its possible. =)

both of those CPU's suck due to their low multipliers.

some infamous p3's that overclocked were 100FSB ones, when switched over to 133FSB turned into mosnsters, such as the 700E turning into a 933EB. the same thing can be said for celerons, the 566 (iirc (8.5x66)), usually made the jump to 850 (8.5x100) or higher, and also some of the 100MHz FSB celerons also made the jump to 133. the most notable of these were the tualatin (.013u) core celerons, but that is another core and more compatibility requirement.

YOUR best option right now would probably to get a slocket that takes FC-PGA2 (tualatin) CPUs. you can buy a 1400MHz celeron which would act very close to a P3, but with pretty much more than twice the clock speed. give it a shot, should be like $50.

nah npo point in wasting 50 bucks ( i am in canda thats like 72 bucks) for an increase in clock speed with no increase in performance.... thanks tho for the help
