Well the Xserve obviously uses FB-DIMM..so it is serial in nature and the latency increases on each channel since all traffic is routed between the first and any intermediate FB-DIMMs.My experience is that you should place the fastest/largest FB-DIMMs in slot one.So: install your new 1Gb FB-DIMMs in the first two slots of each channel and move the 4 x 512 FB-DIMMs to the the second two slots of each channel.This will also have the side effect of reducing your overall thermal profile.Karl On Feb 7, 2007, at 8:11 PM, Seth Norris wrote:I know this is not exactly the correct forum, but everyone that responds to this list is so intelligent that I thought maybe I can get a quality answer here. Now that the shameless flattery (all true though) is over, here is my question: We just received a brand new XServe today (2.66 Xeon / 3 - 750GB SATA / 2GB (4-512) RAM) and want to add some more RAM to it. The thought was to add 4 1GB DIMMs bringing our total to 6GB. However, the Apple doc states "for the best possible performance, install eight identical DIMMs". Does anyone believe that 4GB (8-512) would be a better choice then our original idea of 6GB? Also, does anyone have any experience with DIMMs that did not come from Apple? I would appreciate any advice on this matter as all configuration decisions were made with out me (including the idea of the additional 4GB to be installed by me)Thanks and again my apologies for the non WO nature of this post.
