I have a RAID 1 server with a 3.0GHZ processor. On occassion the POST screen reports the processor as 6.0GHZ and the BIOS screen reports it as 1.4GHZ. It may also return a "machine Check architecture error. After several reboots the error will go away and reappear later on a reboot. The BIOS does not allow BUS speed modifications and the Processor is locked out from overclocking. I see no jumpers on MB for this either. Does anyone have any ideas about what is going on with ?
