All, Is it mandatory to maintain DDR2 timing parameter values tcl - trcd - trp to 3-3-3 for DDR2- 400MHz speed bin?? I want to work with DDR2 at 266MHz, but the DDR2- SODIMM supports CAS Latency of 3 / 4. So can i program my DDR2-266 timing parameter values tcl - trcd-trp to 3-2-2 ??? Is this will be optimal? Please advice, Thanks, Rajasekar --------------------------------- Jiyo cricket on Yahoo! India cricket Yahoo!
