tech question for those w/533fsb mobos

Anyone with a P4 board happen to notice what your agp and pci busses are
running at in DEFAULT settings?
My VIA P4MA PRO533 w/ Apollo P4M266A / VT8235 chipset supports 400/533 FSB
and defaults the agp and pci at 88MHz and 44MHz respectively...
My cpu is Intel 2.40b 533Mhz.
There are no adjustments in the bios to lower these speeds...no
dividers...nothing. So naturally, I'm wondering if all 533 supported fsb
boards run there AGP and PCI bus slots at this speed. If not, then VIA may
have released this board overlooking their bus timings....
Any ideas??

My P4T533 (2CZ Version) has adjustments for this. Default is 67/33
AGP/PCI. You can leave it at this and O/C the fsb without running the PCI
bus too high.

On the other hand, you often see more of an overall performance improvement
by overclocking the PCI bus by 5-10%. 33MHz doesn't go far if it is to
service multiple fast hard drives, a 100Mbit network card, plus audio, and
is often the main bottleneck in a system.
44MHz might be a tad high for some devices, though.

33 MHz can give a false impression though as the PCI bus is 32 bit wide
so throughput is 133 MB/s.

Just out of curiosity, if you set your FSB to 100 vice 133 is your AGP/PCI
66/33?

My Gigabyte MB lets me set the AGP/PCI to whatever setting i want,a necessity
when overclocking,
