Questions and answers
- Which board is better for a home lab?
- The Gigabyte MZ31-AR0. It gives you 16 DIMM slots, DDR4-3200 and dual 10 GbE, which matter more as a lab grows. The ASRock is fine only if 128 GB and DDR4-2400 cover your workload.
- Is the ASRock worth it over the Gigabyte?
- Only on price. The ASRock is used and has no stated price, while the Gigabyte is $797.25 new at TeciSoft as of November 3, 2026. The Gigabyte wins on memory, PCIe and networking.
- Which supports newer EPYC CPUs?
- The Gigabyte MZ31-AR0 lists EPYC 7003 series support up to 64 cores. The ASRock listing only says Socket SP3 EPYC without naming a generation.
- How much memory can each take?
- The ASRock caps at 128 GB across 8 DDR4-2400 slots. The Gigabyte takes up to 2 TB across 16 slots at DDR4-3200.
- Do I need a GPU to boot either board?
- The ASRock has onboard graphics, so it boots without a GPU. The Gigabyte listing does not mention integrated graphics, so plan on a GPU or BMC access.
- Which fits a standard case?
- The ASRock is ATX. The Gigabyte is E-ATX, so check your case supports the larger board before buying.
