Supermicro H12SSL-I Motherboard vs Supermicro M11SDV-8CT-LN4F

Pick the H12SSL-I if you are building a full-size EPYC server and want to choose your own SP3 CPU, fit a large GPU or add-in card, and populate up to 8 DIMMs. Pick the M11SDV-8CT-LN4F if you want a compact, low-power node that boots with a soldered 8-core EPYC 3201 and needs no separate CPU purchase. The H12SSL-I is the more flexible platform; the M11SDV is the simpler, smaller one. Owners of both praise Supermicro's IPMI and build quality, but the M11SDV's fixed CPU and single PCIe slot limit upgrades, while the H12SSL-I needs a CPU and cooler you supply.

• Choose the H12SSL-I if you are assembling a rack or tower server around a socketed EPYC chip and need room for multiple PCIe cards and 8 DIMMs.
• Choose the M11SDV-8CT-LN4F if you want a tiny, quiet, low-power server that works out of the box with a built-in 8-core EPYC and four LAN ports.
