In the beginning DDR2 was not any faster than regular DDR. With improved memory controllers, latency and the like DDR2 has caught up and now exceeds the performance found in DDR in select systems. Mostly Pentium 4 systems with socket 775. DDR2 does provide more bandwidth from the CPU to the memory which is important. I am not sure how Apple has taken advantage of this, but knowing them they did it in a good way. Not only that DDR2 is going to be around longer than DDR.
One other note is that you are going from DDR333 to DDR2 533. Meaning the bus speed is going to be that much faster. ie the difference between a G3 on a 66MHz bus and 100MHz bus. I would agree with your tech that it is faster. Save our LAN! www.coloradogameralliance.com > > Greetings > I bought a refurb 17 inch PowerBook Big AL from Apple and was going > to max out the ram.
