now i understand... tnx polds

the higher the frequency, the better?

the higher the frequency, the more data it can move.

e.g.

DDR2-800 MHz can move 6.4 GB/s ( 800 x 8 )

like i said earlier, if the memory is called PC2-6400, this not only means that the memory is a DDR2-800 MHz, the 6400 is theoretically the amount of data the memory can move (6400 MB or 6.4 GB per second). 800 is multiplied by 8 because there are 8 bits in a byte so 800 x 8 = 6400. DDR2-667 is a.k.a PC2-5336 which means it can move 5336 MB/s or 5.3 GB/s.

you also need to take into consideration the memory response or commonly known as memory latency or timings since what's the use of your memory which can move lots of data but has poor response. this is different with regards to the frequency -- the lower the latency is, the faster the memory response.
