glad to see your in the maximus club the 803 bios is a lot better than previous , just superpi'd at over4.2ghz at 1.6volt , with the other bioses i needed around 1.65 volt just to be stable over 4ghz so whatever asus has done has done the job, if you get an error with pc probe after a crash just reinstalling it solves it, loadline calibrator works rock solid shows slightly lower values than reported in bios but rock solid and never moves, not a lot more time tonight to play about with it but seems a winner to me
