ASRock Z77 OC Formula Review @ OCC
 

But wait, there's more, as the commercial starts. The UEFI BIOS is full of tweaks designed for the enthusiast with preset overclocking profiles tuned by Nick Shih as well as memory presets for use with specific module and speed combinations similar to what you might find on an ASUS ROG board. By using a combination of profiles and manual tweaking I was able to push the Core i7 3770K to over 4.8GHz with the memory running at 2400MHz (higher than it ever has so far); pretty stout results for a combination of parts I thought I had rung the last bit of performance from.
