Is the PCI bus linked to the FSB?

[JC316]

I know that it used to be on the older motherboards, but I am not sure now. I can't overclock when using a plain PCI Geforce 4 MX 420 with this motherboard. It gets pissed and resets my CMOS.

Not like it matters much since I can't play any decent games yet, but it's still perplexing to me.

System is <------- that way.

I believe it is, look for an option in BIOS to lock your PCI Bus. Some boards have it.

Some boards are, some aren't. Mine isn't. It can't hurt looking, though.

Set it to 100MHz.

Dude, he said PCI, not PCI-E. PCI runs at 33.33MHz.

Yeah, I have a PCI-E lock and it's locked at 100MHZ, but no PCI lock. I guess they didn't think that anyone would be using something this old.

Usually it does yes, though it can run at 66Mhz as well, and in the form of PCI-X it could go up to 533MHz.

As for it being linked, most modern boards can lock the PCI frequency, look for the option in the BIOS, if you don't have that look for a divider, it might be there.
