I have one db-server with 8 GB RAM with 2 dual-core, all working flawlessly. I have two web-servers with 4 GB RAM and 2 single-core opterons. I had problems related to RAM becoming corrupt with the server having 8 GB, swapping 4 GB of the exact same type of RAM-modules from another server cured the server. The server that got the RAM-modules did not excibit abnormal behaviour, ran it for hours with memtest (www.memtest.org) without problems. So it very much depends on your motherboard and type of ram etc. Other than I don't recall I had any serious issues in that area except for ata-drivers not being 4 GB clean. I even have some Dell dual xeon's running amd64 and 4 GB RAM :-) regards Claus
