What reviewers say
Gigabyte MZ32-AR0
Owner reports on this board are thin and mostly come from home lab and small business builders rather than large review outlets. The common thread is that it works reliably once memory and firmware are sorted out.
- Stable operation with EPYC 7002 CPUs under sustained load
- Plenty of DIMM slots for high-capacity memory builds
- IPMI management works well for remote administration
- Memory population and BIOS settings can take trial and error
- Cooling and chassis fit are awkward in EATX cases
- Documentation is sparse compared with consumer boards
Gigabyte MZ31-AR0
Owner reports are split. One praises the board for running flawlessly as a rare single-CPU EPYC option, with remote management working after an update. Another reports the board failed and calls the documentation really bad.
Questions and answers
- Which is better for a home lab?
- The MZ32-AR0. It gives you PCIe 4.0 and EPYC 7002 support, and it is cheaper new at $764.05 versus $797.25. The MZ31-AR0 only wins if you need its onboard 10GbE.
- Do I need the MZ31-AR0's 10GbE ports?
- Only if you plan to connect at 10 Gb/s and want to avoid a PCIe NIC. The MZ32-AR0 has no onboard 10GbE, so budget for an SFP+ card if you need it.
- Which supports newer EPYC CPUs?
- Gigabyte lists the MZ32-AR0 for EPYC 7002 and the MZ31-AR0 for EPYC 7003. Check Gigabyte's CPU support list for the exact model before buying, since BIOS revisions matter.
- Is the MZ31-AR0 worth the extra money?
- No, not at these prices. It costs more new and offers PCIe 3.0 and older platform support. Buy it only for the dual SFP+ ports or a good used deal.
- Which has better expansion?
- The MZ32-AR0, because PCIe 4.0 doubles the bandwidth per lane. The MZ31-AR0 counters with four SlimSAS SATA connectors and an M.2 slot.
- How much memory can each take?
- Both have 16 DIMM slots. Gigabyte rates the MZ31-AR0 at up to 2 TB at DDR4-3200, and the MZ32-AR0 at up to 2 TB at DDR4-3200, though one MZ32-AR0 listing states 128 GB.
