Hi Josh,
thanks for your kind reply!
Currently there are 8x 2GB dimms. 4 for CPU A, and 4 for CPU B. According to www.dell.com/.../server-pedge-installing-upgrading-memory-11g.pdf the DIMMs must be evenly arranged, so I assume that the current configuration is (R610 has 3 channels with 2 banks for each CPU):
[A1] [A4] [A2] [A5] [A3] [A6] -- [B6] [B3] [B5] [B2] [B4] [B1]
[2GB] [2GB] [2GB] [2GB] [empy] [empty] -- [empty] [empty] [2GB] [2GB] [2GB] [2GB]
Open speaking, I dont see any solution to fulfill the requirements stated in the PDF for a balanced configuration with following your advice to add 2x 8GB dimms.
Hope you can help/clarify this issue to me. Thanks! :-)
