AGP / PCI bus speed on an MSI KT3 Ultra?

[Pacinamac23]

I have been looking through the BIOS of this board for quite some time now and I have yet to find any settings for the PCI/AGP bus speed. Be it locking the speed, or setting it to 1/5 or 1/6. Does anyone know where these settings are, and if they are not available, are they locked?

I am pretty sure this might have something to do with my poor overclocking results.

I have a KT3 Ultra2 runnin' 166MHz(FSB/RAM)...look in BIOS.

That was my question. I have looked in there, for hours and hours and have not found a setting even remotely relating to a PCI/AGP ratio clock or something to that idea.

on the kt3 at 152 fsb and up, a 1/5th divider automatically kicks in. you can't adjust anything in the bios.

Are you sure about that? I'm running my FSB at 166 on a KT3 Ultra and Sandra shows my buses to be at 84 and 42 for AGP and PCI

the sandra reading is inaccurate. someone on another forum verified with either a scope or something else (not software) and confirmed it. i had my kt3 running at 175fsb and i'm sure some of my components wouldn't have been able to handle being out of spec that much.
