If I'm understanding the Supermicro manual for this motherboard correctly the only way I can get octal channel memory with dual epyc 7742 cpu's is to populate ALL 16 dimm slots with ram as long as the ram is 2666MHz or less (only 8 DIMMs can be used with 3200MHz).
Can someone confirm if this true? Because what I'd really like is to get only eight 2R modules @ 3200MHz (2R is better than 1R) if it will still give me octal channel memory and best performance.
Page 31 of the manual (https://www.supermicro.com/manuals/motherboard/EPYC7000/MNL-2027.pdf) seems to suggest only one channel per slot and so 8 modules would not give me octal channel memory, but I'm not 100% sure.
