zero4zero, good explanantion. THX.
EDIT: Just thought of another question: What if your mobo is NOT dual channel and you put in 2 different sticks with different frequencies, does the bottlenecking still occur?
Also, my new mobo has 4x DIMM DualChannel DDR 333/400 Max 4GB, right now i have 2x512 400mhz ram in there. If i get another 2x512 for the 333mhz channels, will the pc3200 memory slow to 333mhz?
