I have purchased the MSI G45 Gaming Motherboard, and I am very aware of the OC Genie. I am coming from an Asrock Extreme7 Gen3 which for me, was a hassel to OC. So I would appreciate a Guide for this mobo, as I know MSI OC genie SUCKS.
You don't really need a specific overclocking guide for your motherboard as the general principles and methodology are the same on all boards, it's just that the setting names might be slightly different or in different places within the BIOS.
I would start with this guide but any sandy bridge guide should be helpful.
