As you can see on page 46 here - dell.to/2RRpqyJ the R620 would require 24 32GB LRDimms (Load Reducing) in order to achieve 768GB of memory. You would have to use dual or single ranked dimms though, with the R620 you can have up to two Quad Rank dimms, or up to three Dual or Single ranked dimms installed per channel. So if you used quad ranked you would only be able to populate 2 dimms per channel, leaving you only 16 dimms.
