dumbmoney, let me clarify The i840 was a workstation chipset. It was never marketed for servers--for one thing, it could only support 2-way SMP multiprocessing. I know that some people may have used an i840 for a small-scale server, but that's not the market that Intel, AMD, etc. are talking about when they mention "servers." The Alpha 21364 is/was (I assume it will still see the light of day?) certainly a "big iron" server chip, but not the focus of what Rambus has been about for the past several years. The limitation of 2GB per CPU is because of the 32-device limitation of a rambus channel, without repeaters. With repeaters, I guess DEC could increase that to perhaps 4GB/channel, but the memory density would depend on how dense the chips are; with 288Mbit chips (ECC), 32 devices would equal 1GB of DRAM. Using 576Mbit chips (without repeaters) would give 2GB per channel. Assuming one channel per CPU, that might be adequate. In an 8-way system, that's still 16GB of memory
