No one here takes much stock of user reviews. Most are written by the kind of people who shouldn't touch technology.
Memory compatibility issues are mostly due to not properly setting the RAM timings, speed and voltages. Which can be fixed extremely easily, furthering my point above.
I would stick with the board. If you have any problems, RMA it and get the Asus P6X58D Premium (it's a little more expensive). I wouldn't get a new board without USB 3/SATA III at this point.
