Abit VH6 question/problem

A quick question, I have an abit VH6 mboard. Running a PIII 800 @ 900 w/ aircooling only. FSB 150/1/4 all she's got. Temps running 27 to 30C depending on room temp (about 26 to 27 right now- upstairs w/window and ceiling fan going) Usually about 27C and stable. 130 cfm fan in and 100 out w/ps fan and 60mm in top.
Thermalright sk6 w/51 cfm fan. (you could vacuum the carpet with this thing!) My USB optical mouse (microsoft intellimouse) will not run w/this FSB speed. Gotta go back to good ol ball mouse to get mouse capabilities. Any suggestions?

help me! If I put it back to reg bus speed it works fine with opti mouse. Voltage issue?

first time ive heard of a mouse going south from high FSB, well as you may know some things just cant handle out of spec speeds i'm running a Logitech optical wireless at 172 FSB with no problems. You may want to get away from a USB mouse if you want to overclock unless someone else has a better idea.

USB doesnt like higher pci speeds

KInda was expecting that. Have tried drivers, etc., no good. But do appreciate the help!

Have had probs before with usb on this board w/dsl modem, think usb drivers for this version are not too good.

Well solved the mouse problem, had an older optical mouse so I bought a new msoft optical with an adapter for ps/2 use as well. However, this one works on usb bus! Kinda strange but it solved the problem.
