Summary: The problem I have is I receive a Q55 error whenever memory is used in either of memory channel B's slot 1 or 2. All four DIMMS work fine in both channel A slots. The BIOS was flashed to latest build version 1802 and was set to default with no overclocking.
Pros: Other than the fact that I've haven't been able to use this board since I bought it, it seems nice. It has all options I could ever want at this moment, except working correctly.
Cons: I have an Asus Maximus V Extreme Board, which I have RMA'd twice already, but with no resolution to its Q55 error. Suffice it to say, I am severely disappointed with it this product.
