I about bought that Deluxe about 20 times in the last week. Had to keep telling myself no as need to test some more chips out on my P5B Deluxe to make sure it can't get the job done. You can flash that Deluxe to the Premium BIOS but I don't know what the OVP is on it. Hopefully it isn't 1.92v! I can get 1.96v out of mine but need to do the OVP mod to get the full 2.1v. I'm interested in what this 356 D0 China chip can do I have here. It is going under the knife next when I go LN2 again.
