DJ-CHRIS said:Asus boards show 400 instead of 200. However the actual ram frequency is 200, since DDR sends an instruction on the crest and swell (up and down) of each frequency wave.
Exactly, Like Nubius and Chris have said, the Data Rate is 400MHz because the instruction causes the base 200MHz to cut the time of the clock cycles in half, double it's speed.
Saying otherwise would be like saying that the HTT runs at 2000Mhz on a 3200+. The BASE is 200 and its multiplied (actually divided) to increase it to 2000.
