Notes:
1. Max Series (HBM) CPU supports 1DPC (4800 MT/s) / 2DPC (4400 MT/s) to op-
timize the memory bandwidth. Max Series (HBM) CPU supports 1, 2, 4, 8, or 16
DIMMs in Flat Mode as well as Cache Mode, and 0 DIMMs in HBM-Only mode.
HBM-Only mode runs exclusively using HBM memory.
2. For the best memory performance in Flat mode and Cache mode, please use 4,
8, or 16 DIMM configurations. (At least one DIMM per memory controller for bal-
anced configuration)
4 DIMMs -> populate 1 DIMM/iMC (Integrated Memory Controller)
8 DIMMs -> populate 1 DIMM/Channel, 2 DIMM/iMC
16 DIMMs -> populate 2 DIMM/Channel, 4 DIMM/iMC
3. All other configurations not listed above are not supported.
4. For the 2-socket design, each socket has to be populated identically.
