Hi cordob; I don't think so. By the way, I saw some confusion over on the Fool thread about how many pins RDRAM saves over SDRAM or DDR. Since it should be clear to all that (1) pins are free and (2) RDRAM is dead, dead, dead these technical discussions really don't have any relevance, but here's a reference showing a more accurate pin count for a Rambus channel, and straight from the Rambus supporters' mouths: "The attraction over the longer horizon is that we get more bandwidth per pin," Allen said. "Compared to 100-MHz SDRAMs, we need only half the number of pins, and the Rambus approach delivers eight times more total bandwidth." The current 440 LX c hip set from Intel, which supports today's 66-MHz SDRAMs, requires 492 pins. Allen said the Rambus approach requires about 75 pins to implement a 1.6-Gbyte/s channel, and "we are within the pin budget to add another channel." eetimes.com Actual pin counts obtained by turning the little thingies upside down and counting the pins in the RDRAM interface area reduce the pincount advantage to something around 3 to 2, due to the huge number of ground pins that RDRAM requires. If you want to find out more, go do a search on the Intel web site for the pinouts of their RDRAM compatible chipsets. Find the pinouts, and count the pins. -- Carl
