I have a p3 750@1000 the vcore is set at 1.90 on an ASUS P3V4X with 256megs Crucial PC-133. The system runs fine with out crashing or locking up. The only problem I have is that it won't cold boot at this speed. If I shut the system off I have to lower the FSB from 133Mhz to 124Mhz and let it load Windows . Once it has loaded Windows I can restart it and change the bios to 133Mhz FSB and it loads and runs just fine. CPU temps have never gone above 39c and usually are about 35c under a load. Any ideas why it won't cold boot at 133Mhz FSB?

I think it's a problem with the P3V4X but i think there's a work around if you have a fcpga,
You could set the voltage on your slocket to 1.90 that might work (didn't try.....yet), Anyhow I have the same problem tho i have to lower my FSB from 138 to 133.
But I'm sure (almost) that it has to do with Vcore.
I'm gonna try it right now and I'll let you know.
Yep that's the problem, No problem booting my PIII 600 @ 828 anymore.

OK so if I could get it to run at 133FSB with the vcore at 1.80 you think it would be OK? I say the vcore at 1.80 because that is what I boot at 124FSB with. The chip is a slot one so no slocket is there any other work around? Thanks for your help guys

Just give it a try.....cold boot @124FSB 1.80 Vcore, up the FSB to 133 see if it boots (into windows)when it does that shut down, pull the power cord press your Power button a few times,Plug the power cord back in and off you go (or not).
Not that I know of....but when I find something bout that I'll let you know.I think there should be a way to up the Vcore on a slot PIII (it can be done on a slot PII, I believe it's called the B21 trick....if my memory serves me right).
Good luck

No. The B21 trick was for the high/low FSB autoselect, but with the old SECC's you could tape other pins to up the core voltage.
