It'll help keep some friends of mine that do EMI testing for FCC, CE, etc. in business for a long time. Speaking of that, may be another additional cost for Rambus equipped machines...sending out for EMI testing as the frequencies get higher and higher. Tony, I think EMI is another reason Intel is moving to Rambus. The below link indicates this. developer.intel.com EMI: suppression, not containment The 66-MHz Front Side Bus (FSB) and SDRAM motherboard clocks and 150-MHz L2 cache Back Side bus (BSB) interface clocks are the primary EMI radiators in Pentium® II processor-based systems. Future systems will include 100-MHz FSB and SDRAM, 800MTs Direct RDRAM, and 266MTs AGP-4X interfaces, as well as 450-MHz Single Edge Contact (S.E.C.) cartridges housing future Pentium II processors. The FCC's new open box regulations make containing EMI radiation inadequate. Instead, EMI must be suppressed. Intel is pursuing three technologies to do this with minimal cost impact: Complimentary clocks, on all future Pentium II S.E.C cartridges and the Direct RDRAM interface, reduce emissions by canceling radiation from the primary clock. Spread-spectrum clocking, standard on future clock drivers, varies the clock period in small increments to reduce the energy radiated at any given frequency. Intel refers to new FCC Open Box regulations. I have looked but have not been able to find out what these new regulations are and the impact on the PC industry. Could you ask your EMI testing friends about this? Regards, Jim
