Add 32G to R710 Server
I'm trying to upgrade the RAM in an R710 server (2 processors).
The original configuration of 32G is 8 x 4G DIMMS (Optimized)
DIMMS are in A1, A2, A4, A5 and B1, B2, B4, B5.
I have 2 x 16G DIMMS to add, and I cannot find a valid combination for how to add these in to make 64G.
I thought a channel could have just one DIMM, but it seems like that doesn't work.
No Events found!

Boogr,
The issue you are having is due to the servers memory channels. With the number of 16GB dimms you have there isn't a plausible way to make the channels match. Memory modules of different sizes can be mixed within a memory channel, but all populated channels must have identical configurations, except for channels that are unused.
So the only way you could do this would be to only have 2 16GB and 2 4GB to make them match, which doesn't reach the desired goal. Or push to 4 16GB dimms, which can be installed on A1, A2, B1, B2 and then have the 4's on A4,5,7,8 and B4,5,7,8. Which would exceed your desired amount 32GB at 96total Gb.
You can find more information on the servers Memory Population here.
Let me know if this helps.
