HAVING PROBLEMS GETTING CELERON 566 TO 133FSB!!!!!!???

[mike]

no matter what i do i cant get my celeron 566 on an iwill sloket II in a soyo 6vba133 mobo. it has the via apollo 133 chip. right now i run it at 118fsb with the PCI at 69 and the AGP at 79. supposedly with the 133fsb the pci will be 33 and agp 66, so why cant i do it. i turn my machine on and dont get any beeps, nothing on the monitor. i have the voltage right now at 1.9v. i have 64mb pc100 gereric ram. win2k. anyone got any ideas? thanks!

Getting to 133FSB would mean 1130MHz, that's a little unrealistic don't you think?! Well in case you really want to try, you can try to increase the input-output voltage of the mainboard. I have to raise the Vio to 3.8Volts to get my Celeron800 stable at 133FSB (1066Mhz) but I don't really like the high voltage cuz officially the default is 3.3 and my Abit mobo already defaults to 3.5.

try pc 133 ram, and what cooler have you got?

Sounds like it's an exceptional C-566 just making it to 118 FSB. That's amazing. If you can't even get that thing to post at 133 FSB, it probably ain't going to happen. Lots of those CPUs won't make 1 gig.

Also, there is no way your PCI bus is running at 69 MHz at 118 FSB. I don't know of any cards that will run that far out of spec. I'm guess the PCI bus has a 1/3 divider putting the PCI bus at 39.5 MHz, which still a little on the high side. The 79 MHz for the AGP sounds right if you have a 2/3 divider.

Ya its pretty diffecult to get a 566 to 133 fsb i can get mine to 120 stable and post at 126 no more but maybe you might get lucky



566 @1020

133mhz FSB seems unlikely because that would mean you're doubling the speed of the chip.

sorry i meant to say 39 for pci speed

homemade water cooling with 80 wat pelt

i doubt it will post that high, Intel has trouble getting any of its chips up to 1.1ghz. So you should be very happy with what you have so far! If you get it to work that would be utterly amazing, truly an act of god!

I would be extremely careful. If you don't have your cooling perfect at frequencies that high you can fry your chip. I had a Celeron 566@994 (117FSB) and the HSF wasn't attaching well to the chip (ALPHA PEP66t) and the CPU started to lockup. I'm still trying to get to the bottom of it, I've been lapping and rebending the clip and whatnot, but stability is still elusive. I don't think Intel ever had running a Celeron 566@1ghz in mind when they designed it, so don't be surprised if it doesn't. Running a 566 at 133FSB sounds ridiculous, but maybe with a good Peltier or water cooling setup and the 1 super duper awesome Celly out of 1,000,000 that slipped by Intel's checks....who knows? Good luck to ya tho...

(I made this Celly POST at 1054, but it doesn't get past the POST screen.)

I don;t think it's THAT unrealistic. I think I have seen in done somewhere before with supercooling. But you've already used pretty agressive cooling to get that far. Some will do that with air cooling, sounds like you have already maxed out your chip. But I would be inclined to stick some more voltage in it and see what happens. But then I'm just an idiot.
