Gigabyte MZ31-AR0 vs Gigabyte MZ71-CE1 Motherboard

The MZ31-AR0 is a single-socket EPYC 7002 board aimed at one CPU and 16 DIMMs. The MZ71-CE1 is a dual-socket board built for two EPYC 7002/7003 chips, so it carries far more compute and memory headroom. Buy the MZ31-AR0 for a single-CPU build where one processor and 16 DIMM slots are enough. Buy the MZ71-CE1 when you need two sockets, PCIe Gen3 expansion cards, or a large memory footprint. Owners of both report boards that work as described; the MZ71-CE1 is the more expandable platform, the MZ31-AR0 the simpler one.

• Choose the MZ31-AR0 if you want a single-socket EPYC 7002 platform with 16 DIMM slots and on-board M.2 storage.
• Choose the MZ71-CE1 if you need two EPYC sockets, five PCIe expansion slots, or a memory footprint well beyond 64GB.
