I just found out the pcb version of my a7n8x motherboard is 1.4 Ready to buy newer memory to go with my barton 2800+ and even though my manual says it supports DDR400 because of the revision 1.4 I'm not sure it does. Would I be on the safer side if I purchased a Premium 512MB PC 2700 333MHz 64x64 DDR 184 memory? and if so would I need to buy 2 of these for my board or can I just buy 1 and buy a couple more later on down the line?
