I posted this in the main forum but it didn't work so i thought i'd try here... So i have the Asus A8N SLI-Deluxe and it has 4 ram slots. They are as follows: 1A 1B 2A 2B. 1A is closest to the processor and moves outward. I just bought a new heatsink and fan and it's pretty big. I have 2 pieces of 512 corsair XMS ram. They are pretty tall. If i have the two ram sitcks installed in 1A and 2A (for dual channel) the ram in 1A will hit the heatsink and will prevent it from sitting on the processor correctly. My questions are: 1) If i put the ram in both 2A and 2B will it recognize the ram and 2) If i put the ram in 1B and 2B will i still have dual channel?
