I have a soyo dragon ultra kt333 I just wanted to know the pci/agp speeds so i dont run it too far out of spec for example if I wanted to use a 155 FSB or a 140 I kinda want a table that show what the defaults should be and what the would be @ certain fsb
PCI spec is always 33MHz, and AGP is always 66MHz. Whereas nForce2 has a PCI 'lock', so that the PCI can be locked at 33MHz regardless of the FSB, many m/b's use dividers as previously explained. Usually the dividers kick in automatically, depending on the FSB, so it makes OC'ing more difficult if you can't get the FSB to the next integer multiple of 33MHz.
you are right zikronix. At 166mhz (maybe even a couple mhz lower), the 1/5 PCI divider, and 2/5 AGP divider kick in on KT333 boards. I'd try to run right at 166mhz or higher if possible. running around 160 with a 1/4 PCI divider (to check your PCI speed run sisoft sandra, theres an app that will show your PCI frequency) will cause data corruption on most HDD's/setups. I would stop at 155 with a 1/4 divider....again i'm pretty sure the 1/5 divider on KT333's doesn't kick in till 165 but i could be wrong
