Prepare for the Ivy Bridge.
The Z77A-GD55 is running MSI’s latest UEFI BIOS, with a rather smooth looking interface.
As usual my only gripe with this UEFI BIOS is that digging into the sub-menus is slightly tricky because the mouse clicks don’t always register. And once again there are no explanations on what any of the various settings do to help those new to overclocking, or just people curious to fiddle around in the BIOS. Otherwise the UEFI remains the same as previous MSI motherboards such as the Big Bang XPower II.
For overclocking the Z77A-GD55 I simply went into the ‘OC’ menu, changed the CPU ratio to ‘47’ and CPU Core Voltage to 1.45v and got an effective and stable overclock of 4.7GHz.
