Intel Z77 Chipset motherboard Review @ OCC
 

Overclocking the MSI Z77A-GD65 was more of the same type of Sandy Bridge overclocking we have seen in the past on the Z68 as well as the P67 platform with simple bclock and bclock multiplier adjustments to creep up on the highest possible clock speed. This of course continues to be a limiting factor in how far your chip will overclock. The MSI Z77A-GD65 proved to be fully capable of delivering an overclock similar to what I have reached on Z68 and P67 boards in the past with the test CPU. This means a clock speed just north of 4.9GHz with a maximum bclock multiplier of 47 and a bclock that ranges from 104MHz to 105MHz using an applied 1.495V with LLC set to high. Memory overclocking is limited on my CPU but still it managed to pull off a 2133MHz+ clock speed.
