And the RMA arrived. Looks like this kit is... sh*t compared to the other kit I had. Won't even POST at 2000MHz 7-8-7, whilst the other kit was stable at that speed at stock voltage. When it does post the system can only find 4GB, so I assume on of the sticks is just crap. Errors out in memtest at 2GHz 8-8-8 too. Testing now with a slight voltage bump :(
Oh yeah, and my system only posts half of the time. The other times it will be stuck in a post-loop where the only solution is to clear CMOS, even though the settings proved stable before rebooting.
