I recently purchased the majority of the parts from the $1000 system published here in august 2012. The computer posts, but when I place either of the two memory sticks into either A1 or A2 (the two slots closest to the CPU) I get a 4 beep error. According to ASRock, is a system timing error. To take advantage of the dual channel memory I need to place the two sticks into A1 B1 or A2 B2. Right now I can only place them both into B1 B2. Is there anything that I am missing here or is this an issue with the mobo?
