technically no mobo offically supports over pc3200, if youll put pc4000 it wont give any better performance then pc3200 as it will run as pc3200 unless youll overclock (ddr over pc3200 is just for overclock headroom a person that dont do overclocking should just get a pc3200)
DFI is made for OC. The mobo will downclock it to PC3200, the PC4000 rating is from the ram manufacturers telling you what its guaranteed and stock operating speed is, it can be OC'd faster.
k so, yea im gonna edit my sig. So when i put in the PC 4000, it will de downclocked to PC 3200 speeds, but then when i start to OC my hardware i can bring it back up right? is that how it works?
