Some BIOSes allow you to change various settings to do with bus speed, DRAM timings and the like. Have these got screwed somehow? Can you "Load optimised defaults" in the BIOS setup and does it change anything and/or affect the speed? -- Pigeon Be kind to pigeons Get my GPG key here: http://pgp.mit.edu:11371/pks/lookup?op=get&search=0x21C61F7F
