Maybe i should phone my suppliers and chat to them about this issue with the board. It didn't bug me because i saw the one BIOS update lists a problem with setting voltages for Vdimm and the RAM i was previously using was running fine at 450mhz @2.0v with 5 5 5 12 timings, so i thought when the crucial's arrive i will update the bios, tried that but it hasn't resolved the issue.
