Does it matter which memory slots you use. I got a MSI KT6 Delta FLSR Board and 2x512MB 3200 OCZ EL Platinum Memory. Does it matter if i put the memory in slots 1+3 or should they be in slots 1+2. I ask because I always used 1+2 and as these memory sticks get real not when playing games I thought 1+3 would be best to let alittle air in between for heat to escape. Also my board supports 4 memory banks with DDR400 what does this mean??
