Ksantillan06,  Neither of your suggested configurations will work. A couple reasons why, first is that when 2 processors are installed the dimms must be identical to both processors. Second is that each side has 3 channels, as seen bellow, and they will need to match as well.  [IMAGE] So what I would suggest is to place the 16gb dimms in the white tabbed slots and the 8gb in the black. If the dimms are compatible then that should allow the configuration.  Let me know how it goes.
Hi, Are the following memoryconfigurations supported in the R610?  128Gig: :emotion-29::emotion-29::emotion-29:[8:emotion-29::emotion-29: xx xx [open][open][16][16][16][16]  160Gig: :emotion-29::emotion-29::emotion-29:[8:emotion-29::emotion-29: xx xx [16][16][16][16][16][16]  If not, can you please suggest how can I have 128G and 160G with a mix of 8Gigs and 16Gigs?  Thanks in advance.  Kevin
