Putting the screws to the MSI Z68A-GD80 G3 gave me almost identical overclocking results as the B3 revision did. No surprise there! The way to the promised land is through adjustments of the bclock, clock multiplier, vcore, and turbo boost settings. The CPU I am using needs the PLL overvoltage option enabled to reach a multiplier greater than 44 and really does not care to run over 47. But it is tolerant of increasing the bclock at higher multipliers. On this board, that equated to a bclock 105.6MHz. The vcore needed to get to 4.96GHz on this chip is in the 1.48 to 1.49 range, depending on the board and how the Load Line calibration options are structured to manage the vdroop. In this case, a setting of 1.485v in the BIOS would show as 1.472 under load.
