It is possible that there are some hiccups with this board and the CPU. You should do what is suggested in the Asus thread and try updating the BIOS, if at all possible, try changing the memory timings and voltage to fit your G-SKILL memory specifications exactly from the instruction manual. Do not do any of this unless you absolutely have to. You are using a hefty amount of RAM, and if timing or voltage issue, this could push things over the edge. These timings and voltages should be published for the exact type of G-SKILL memory you purchased. If trouble continues, you should CAREFULLY reseat the processor and re-apply thermal compound. If the seating is off, or there is a problem with the thermal tape/compound, you could have an overheating issue or some strange issues. However, since following Torrent's suggestions, if you do not have any further problems, don't even go near this as an option ever. If experiencing continued problems, as a last resort, make sure the memory is firmly seated properly on the motherboard, and also that no metal parts or screws are hanging around under the board. Ensure that all connections being made into the motherboard are solid.
Finally, as a last resort, if this problem does pop up again, consider RMA'ing the motherboard. However, it does look like this was a software issue. TorrentG knows his stuff in this case. A lot of times the motherboard tools and drivers are really bad news, including the stuff from Gigabyte as well.
