No problem.   Let's first talk about the channels. You'll have your A bank and your B banks, which will be made of channels 0, 1, and 2 each. Channel 0 is A1 and A4 for processor 1 and B1 and B4 for processor 2. Slots 2 and 3 (for each bank) would have their own channels (IE channel 1 in the A bank is A2, but B2 in the B bank).   Do you know if your server is has one or two processors? If only one, we just need to be concerned with the A bank. If you have 2 processors, we'll want to populate the A bank correctly, then mirror that configuration to the B bank.   What I'd consider trying in a 2 proc config would be: A1, B1: 32GB A2, B2: 16GB A3, B3: 16GB   Be advised though, this config may still not work. The manual doesn't explicitly call out support for 32GB DIMMs and I don't see any in my parts list. I do see some 16GB dual-rank RDIMMs, so I don't expect issues there. I'm just not 100% on the 32GB DIMMs. That said, they may still work fine. My  old R710 ran both unvalidated memory and unvalidated drives for years.  
Hey all, I have the following memory sticks (six in total): 2 x 32GB  4 x 16GB and I'm unsure as to how to configure them in my PowerEdge R410. I've tried a bunch of arrangements and keep getting DIMM mismatch message upon boot. Any help would be really appreciated.
