agp/fsb and pci/fsb buses

i have a gigabyte ga-6oxc mainboard and a celeron 633.i can't adjust agp/fsb and pci/fsb multipliers, mainboard does it itself.
i adjust cpu as 9.5*100 and the computer opened but windows didn't.is there anything to do with this problem?
since windows doesn't open i can't see fsb and pci buses' speed,66-33 or 100-50?
also i thought first i must overclock then setup windows so that windows can open.is it true?
thanks for your advices.

I'm not aware of any motherboards that allow the user to manually adjust the PCI/AGP dividers. They may be out there, but the few I've had experience with are self-adjusted.

Probably not loading windows because of such a high step (from 66 to 100). I looked through your manual but didn't see much on setting the FSB speed. Are the only options 66/100/133? If that's it, you may be stuck trying voltage bumps to get a good boot at 950.

What memory are you running? And what settings do you have it at in the BIOS? When I've had trouble loading Win but POSTing okay it's been memory related most of the time.

And to answer your question about the bus speeds: they're probably at 66/33.

no.there are a lot of options for fsb.
68-70-72-75-77-83-90-100 and goes on but in 83, fsb=agp.
my gigabyte tnt2m64 freezes at 88mhz so when i boot at 9.5*100 it must freeze too if fsb=agp.from here i saw that at 950 pci=33 and agp=66.
the core voltage is 1.85v.
i have a 128mb 133mhz memory.it worked at 116mhz for a month.

but i can't find any answer to this problem.

At 83 FSB the AGP should be 83 also. 84 is usually where it ticks over. So at 88 you would be running an underclocked PCI/AGP bus which should be good, but I don't know how it works in real-world situations.

I'm having a similar problem with an 1100 trying to cross the next divider level at 123/124 and it seems to be a voltage/cooling issue. Not saying that's your problem since it could be the other bus speeds, too, but it might be something to look at.
