P3 1000 Clocking

[SanDiegoPaul]

I'm using an Asus TUSL2-C board, and a Pentium 3 1G flip chip. It's using an IBM 7200 RPM drive and 512MB of Micron Ram (133) Great machine so far and solid as a rock. I wanna go faster ;-))

I've run the board up to 1200 at times, and upped the core V to 1.8 from 1.75 but had mixed results... losing some stability. <<DUHHH! you say, it's supposed to be less stable when overclocked?>>

Every other machine I have overclocked has been quite stable ... and I'm looking for feedback from folks with similar setups. Or at least those w/experience overclocking that chip.

That is probably your standard coppermine PIII 1 ghz. Do you have the 100 mhz FSB model or the 133 mhz FSB.

The problem with the PIII 1 ghz CPU is that it is near the limit for that die size (.18 micron coppermine). There is little headroom left for overclocking and 1.2 ghz is at or beyond its OC potiential.

If you want to OC on your present mobo, do what Oldfart is talking to me about doing. Get a Celeron (.13 micron Tualy) 1.0A (1 ghz 100 mhz FSB, 256) which is basically a full Pentium III 1 ghz native to 100 mhz FSB. Newegg has them for like $77 Retail Box. Oldfart says they can OC to 1.4, maybe 1.5 mhz.

It is the 133

Thanks ... your thoughts kindof verify my suspicions. Anyone else out there with more info/input/feedback?

This machine sure does ROCK! compared to what I replaced with it. I had a P3-600E OC to 800 but the drive was a 10g WD 5400 rpm so the whole deal really didnot break any land speed records! That one WAS the 100mhz chip and I can see how much easier it is to o/c them rather than the 133's

If you have the 133FSB... you can go see if you're lucky enough and set the FSB at 150-160 for an overclock of 1100-1200 respectively. Keep in mind that your PCI will be out of spec 37-40 and would probably corrupt data sooner or later. If you're like me and got a dud of a 133FSB then you probably wont get that far with that chip in the first place. That's the reason I got a 100FSB version and now i have it running at 1.33GHz. But what are you doing with a coppermine anyway when you have a tualatin capable board? I agree with the tualatin suggestions... those can overclock a lot easier than any of these chips. Just my .02.

I agree with BoYrAcEr about the comments on the FSB version of Pentium III's. The general wisdom for overclocking has always been to get the 100 mhz FSB version for OCing headroom. Get Tualy!
