I've been looking at this motherboard for a system I'm going to build... http://www.tigerdirect.com/applications/SearchTools/item-details.asp?EdpNo=3940043&Sku=B450-2350 The confusing stuff.... "Memory Expansion The P31-A7 provides 2 DIMM sockets using Dual Channel 240-pin DDR2 with a total capacity of up to 4GB-32/64bit. You can install DDR2 533/667/800MHz Memory. (Support DDR2 533MHz While Using FSB 533/1066 CPU)." I'm not sure what they mean by... "(Support DDR2 533MHz While Using FSB 533/1066 CPU)." Does this mean I can only use 533MHz RAM with 1066 FSB processor?
