Thanks Geoff,
So, just to confirm, each channel could have, say, 1x 4Gb RDIMM and 1x 8Gb RDIMM, giving a total of 36Gb?
Or I could go with 1x 4GB plus 1x 16Gb per channel giving a total of 60Gb?
The current 4Gb RDIMMS are single rank modules. Is it possible to have single and dual or quad rank modules in the same channel?
