Dan,And when Rambus starts getting a bad rap because of incompatibilities... Now you're getting into one of the things that Intel/Rambus has absolutely done right. First they've set up very stringent testing and validation processes for every single component involved in the RDRAM product. There won't be incompatibilities because anyone shipping a Rambus-related product has to have it certified. They have very strict design requirements, testing requirements, etc. The SDRAM business, on the other hand, has a significant history of building incompatible products. Designed by committee and controlled by no one. Others on this thread have already heard the story, but I bought one of the first SDRAM systems from Gateway in 1996. When I went to upgrade the memory from 32M to 65M in 1997 or 1998, I wound up having to pay Gateway $300 for the DIMM instead of paying Crucial $200 because Gateway had implemented a spec that turned out to not be the "final" SDRAM standard. (Incidentally, Crucial was a pleasure to work with -- their tech support guy sent me two replacement parts at no charge before he figured out that Gateway had done their own thing). Likewise, when SDRAM was moving toward 100Mhz parts, Intel finally had to step in and define the PC-100 spec because the various vendors parts weren't working together. The PC mobo designers, DRAM mfrs, et. al. have a history of "sloppy" design. To reiterate one of unclewest's points, it was DDR that the president of Sony called "unstable", not RDRAM. Intel and Rambus have done exactly the right things to ensure that the system works together right from the start. Dave
