Good Q I hope someone responds I'd be interested to know as well if you do get one yourself I hope you report back here what you find. Lord knows nvidia sata/raid can use all the help it can get. I'm going to assume, based on you sig, the bios you had before you updated was the 1203. Are you saying you had to make no adjustments what so ever to maintain stable at 4.05 with the 1402?
