Hello   You shouldn't have any issues switching from Advanced ECC.   Also, after it's swapped it looks like I need to move the memory from slots 2, 3, 5, 6 to 1, 2, 3, 4? If all of that is Ok, then when I add the dual rank 16GB sticks will they need to be put in slots 1 and 2 or some where else?   The T320 has two tri-channel banks(1-3 and 4-6). You should not mix memory within a bank. In previous generation servers we did not allow the type of population you are planning, but 12th generation and later servers support flexible memory configurations. That means that we have very few population restrictions. You can put the memory almost anywhere you want. That does not mean that any population will work or be supported. It just means that we do not block non-optimal memory configurations as much as we did in the past. The best population for what you are planning would be: 16GB - 1,48GB - 2,3 5,6 Thanks
Last year I got a T320 with 4x 8GB 1600 single rank memory setup in ECC. I'm looking to up the memory in the system now and would like to purchase 2x 16GB sticks and use the remaining slots. I know the other slots are disabled when setup as ECC. The server is running VMWare 5.5, will it have any issues if I swap the memory from ECC to Memory Optimized? Also, after it's swapped it looks like I need to move the memory from slots 2, 3, 5, 6 to 1, 2, 3, 4? If all of that is Ok, then when I add the dual rank 16GB sticks will they need to be put in slots 1 and 2 or some where else? Thanks for the help.
