TOP CRITICAL REVIEW
Don't go too high on CPU voltage

Pros: Best bang for your buck if oc'ing voltages don't fry it or your CPU. It comes with bios auto oc and Windows oc software. I haven’t tried them. I’d rather do it manually. It has bios flashing within the bios, copy the bios file to a flash drive or leave it on your hard drive, boot into the bios, hit instant flash and it will find the file and flash the bios; I/O panel clear cmos button, internal power and reset buttons, LED port 80 diagnostics display, and mounting holes for socket 1156 and 775 heat sinks.

Cons: Board is about 1” less in width which crowds the ram slots closer to the CPU socket. Some wider heat sinks will block the first ram slot. The Cooler Master Hyper 212 Plus heat sink's fan just clears the first slot. The front panel audio header is in the bottom rear corner and the floppy (if you have one) connector is beneath the lowest expansion slot on the bottom edge. Longer video cards may hang past the forward facing SATA ports. The front panel header uses 2 adjacent pins for the power LED. Most cases have a 3 pin power LED plug.
Bios settings are not in the written manual but in the user manual on the CD.

I purchased this board based on the great reviews of Asrock's 1366 MBs. This is a budget board with only an 8 x 2 power phase and lacks over current protection. Asrock is currently working on a bios that will enable built in over current protection. Until then I suggest that if you are oc'ing your CPU to keep CPU voltage <1.35V or lower. A well known hardware review site killed 2 of these MBs oc'ing an i5-750 to 1.40V.
