Does anyone have a link which explains memory types?
Getting confused between DDR400/333/266 and PC3200, PC2700, PC2100 etc...
DDR 400, 333, and 266 are the rated speeds of those DIMMs. It IS
confusing sometimes. DDR = double data rate, meaning those DIMMs
actually run at 200, 167, or 133 MHz, respectively, but are able to move
data twice per clock cycle (if the mobo/processor supports it that is).
PCxxxx is the burst data rate for that RAM per second. DDR400 RAM can
transfer 3200 bit/s.
Your motherboard should tell you which model you need. One of the DDR
speeds should match the rated bus speed of your mobo, or some multiple
of it.
