I built my friend a ShuttleXPC with a Barton 2500+ bout a year ago, and i just noticed as he booted up one time, that his cpu is rated as a "1900+" in the boot screen, as well as in the hardware manager. So i fixed the fsb to 166, and everything went to normal, but not the pc is very unstable and crashed several times. I thought it could be the ram but its dual channel pc3200 so i didnt see a problem there. I have no idea whats goin on with it now, any suggestions?
