simple overclock question.

i've been overclocking for a while with mostly success. my tyan trinity 400 motherboard (via apollo pro 133) isn't the best board out there, but wasn't too bad for its time. anyway. we all know that you overclock the FSB, you're going to be overclocking the agp and pci bus too. well, I never really thought of this too much as i never overclocked THAT much. up till last week the highest I ever ran my FSB speed is 140mhz to get my intel 500E @700mhz. but now I got my p3 866@ 975mhz using 150mhz fsb speed. keep in mind that my board is designed for 133mhz bus speed. anyway, i ran sandra 2000 last night and found my agp slot running at 75mhz (1/2 FSB)!!!! Holy God, the agp slot is designed for 66mhz. that is waaaay over spec. but so far no problem. looped 3dmard 2001 15 times and got no glitches or lockups so looks like my Geforce 3 Ti200 (@230/450mhz) doesn't mind the 75mhz freq. my question: don't you think if a board supports higher FSB speeds that it would be intelligent to automatically keep the agp/pci freq's as close to spec as possible?

what a joke.

The newer KT333 mobos have PCI/AGP dividers which keep it more in spec. ;)

For the AGP bus, and the newer video cards, 75MHz is a walk in the park. When you start getting into the 90MHz+ range on the AGP, then you need to be careful.

yeah, i know

but even back then, you'd think they would have thought of that and integrated it into the boards. oh well. back then, they didn't bank on everybody super overclocking either.
