GIGABYTE MX33-BS0 server motherboard, LGA 1200, DDR4 3200, 128GB max

Micro ATX server board for LGA 1200

The GIGABYTE MX33-BS0 is a Micro ATX motherboard built for single-socket servers using the LGA 1200 platform. It supports Intel Xeon E-2300 series processors and 11th Gen Intel Pentium CPUs with a TDP up to 95W. The Intel C252 Express Chipset provides the core I/O backbone for entry-level and small business deployments.

Suits Xeon E-2300 builds.

This board fits builders targeting a single Xeon E-2300 processor with up to 8 cores and DDR4 3200 ECC memory across four UDIMM slots. It is not for systems requiring two physical CPUs, support for processors beyond the listed Intel families, or memory capacity above 128GB. Buyers needing more PCIe lanes than the CPU and PCH provide should look at larger form-factor alternatives.

One PCIe 4.0 x16 slot from the CPU

The primary expansion slot delivers PCIe 4.0 x16 electrically when a Xeon E-2300 processor is installed, dropping to Gen3 with a Pentium CPU. A second slot runs at PCIe 4.0 x4 from the CPU but becomes unavailable with a Pentium. The single M.2 M-key connector operates at PCIe Gen3 x4 from the PCH and accepts 2242 or 2280 cards.
