"..the data transfer rate will be 1.5 times faster... ..the change was made possible by "assuring the operating margin, including the timing margin."... ".. almost no changes would be needed to printed circuit boards (PCB)" Yeah right <g>! They probably will need to reduce the number of RIMMs per channel to 1. Otherwise they will need to perform thermal re-configuration of time domains every millisecond, or it may not work at all due to wide fluctuation of memory patterns in real workloads, with heavy jumps in dissipated power leading to wide temperature fluctuations. [changes in board temperature cause changes in signal propagation speed, which in turn move the time domain boundaries out of synch. BTW, there will be 1.5 more boundaries along the Rambus channel at 600MHz.] Or they need to request replacement of commercial FR4 by some other space-grade plastic like teflon... "The firm has said that 600MHz is the ceiling" This is probably the only true statement from the company. How nice the technology must be...! I wonder who would ever use a technology without margins? Little fluctuation in your manufacturing process, or in user environment, and you hit the ceiling. Bumm! - back to RMAbus :) :) :) - Ali
