Jul 22, 2009 I recently purchased an ASRock 780GMH/128M systemboard, 2x1GB Patriot PC2-6400 (DDR2 800) (systemboard supports 1066), an AMD Athlon 64 x2, and a 480 watt PSU. When I place the RAM into slots 2.

Types Of Ram Slot
Hello, I am new to this forum.
Yesterday I purchased an Asus Maximus VII Ranger motherboard, and 2 RAM bars (Kingston 8GB each, 1600Mhz).
I have a couple of questions.
1) The guide suggests to plug these 2 bars in slots DIMM_A2 and DIMM_B2.
I did that but the computer would recognize only 8MB (I am using Win7 64-bits which I reinstalled completely following the change in motherboard).
I suspected that one of the RAM bars may be defective so I swapped them. Still using DIMM_A2 and DIMM_B2. After swapping, the computer would not boot. Worse, I swapped them back to original position and while before the PC would boot and run normally (although showing 8GB of RAM only), not the PC doesn't even boot at all and I get an 'FE' QCode (which I think is not referenced in the manual, not that I could see anyway). I tried to boot using only one RAM bar at a time in DIMM_A2, DIMM_B1 and DIMM_B2, but the PC wouldn't boot.
What does work:
1 RAM bar in DIMM_A1 (PC runs smoothly although of course showing 8GM RAM only)
2 RAM bars, one is DIMM_A1 and one in DIMM_A2. PC runs smoothly and showing the correct 16GB. This suggests to me that both my RAM bars are in fact NOT defective and that may be at least one of the DIMM_B1 or DIMM_B2 IS defective.
Now that my PC is running fine and showing the correct 16GB of Ram, I am reluctant to try anything further and I do not plan to install further RAM bars.
Does someone know what happens, and am I losing performance if I have my 2 RAM bars plugged into DIMM_A1 and DIMM_A2 instead of DIMM_A2 and DIMM_B2 as recommended in the manual ?
2) I see from the guide that this motherboard is capable of handling DDR3-3200Mhz. Will such RAM have noticeable benefits over my DDR3-1600Mhz ? One area where I 'think' the 3200 will help is when encoding DVD into MP4. But I am not sure.
Thank you.

PS: this motherboard is awesome !
