Knock me down with a feather.
A-DATA received a validation from Intel for its DDRII 533 unbuffered DIMM back in April, and after a length of research and development, it had its DDRII 533 So-DIMM and DDRII 400 Registered DIMM pasted by Intel in June and July.
According to A-DATA, the most important improvement of DDRII memory modules over DDRI are the Posted CAS and the additional latency function, as well as the Off Chip Driver program and the new power down mode. We'll take your word for it, A-DATA! ยต
