You are wrong. Please stop distorting facts. Your comments about "effective memory bandwidth" including pagefile considerations are complete waffle. It's not a case of paging to disk, it's a case of whether data has to be read from disk, or from a file/database cache in RAM. The important RAM consideration in a server is most definitely capacity rather than bandwidth. With current available Rambus technology, for 4 GB RAM, you would need, I believe, 8 Rambus channels. This would make for a very expensive chipset giving peak mem bandwidth of 12.8 Gb/s. It is rare to find a server with more than a 1Gb/s network connection (usually much less) so such a chipset would be a waste of resources. SDRAM/DDR performance is plenty. If a single channel Rambus chipset could give multi Gigabyte RAM capacity, then Rambus server chipsets would be justified. The capacity is the only consideration for not having RDRAM in servers. Cost/performance are irrelevant in comparison.
