I recently used softfsb and raised it to 112. I have an Asus K7M mb with an Athlon 700 T-bird and 128MB of Micron Pc133. After raising it to 112 I got blue screens and crashing. I lowered it back to default and now I still get blue screens that say there is a TBS MONTEGO PCI error. My sound card is an older Montego A3DXstream. I take the sound card out and everything is fine. I tried to reload all the drivers first and that didn't work. Can raising the FSB ruin a sound card?
