Hi everyone,

I just bought an A7N8X-E with nForce2-Ultra 400 chipset and wondering.

I saw that the AGP and memory frequencies are asynchrones to the
choosen FSB and could be set individually (the memory is percentage
relative to the FSB, OK). But what about the PCI bus ?

I mean : When I set my FSB to, say 150Mhz, what is the frequency used
by PCI ?
Does it stay to 33Mhz whatever I select for the others ?
Or is it calculated by a divider like in older chipsets ?

The A7N8X BIOS definitely does contain an AGP bus lock at 66MHz.
However, what about the PCI bus lock at 33MHz? For this question we
headed over to ASUS and asked them what was going on. ASUS's response
was simply that they have a PCI bus lock set at 33MHz and that you have
nothing to worry about as far as running your devices out of
specification while performing FSB overclocking.
