Single-processor Xeon platform

The GIGABYTE MS33-CP0 is an E-ATX server motherboard built for one 4th or 5th Gen Intel Xeon Scalable processor or an Intel Xeon CPU Max series chip in the LGA 4677 socket. It targets compute nodes that need eight-channel DDR5 memory and PCIe 5.0 expansion in a single-socket design.

PCIe 5.0 lane allocation limits

Three full-length slots deliver Gen5 x16, x16 and x8 electrical connections, while a fourth slot shares its Gen5 x8 lanes with the first slot. Two MCIO 8i connectors provide four Gen5 NVMe links, and the single M.2 slot is restricted to PCIe Gen3 x4 from the PCH.

Eight-channel DDR5 capacity ceiling

Sixteen 288-pin RDIMM slots support DDR5 5600 for a maximum of 4 TB across eight channels. Builders needing more than one processor, more than sixteen DIMM sites or Gen5 speeds on the M.2 interface must choose a different platform.

Questions about this item

Which DDR5 speed should I select for the 5600 MT/s memory slots?

Use DDR5-5600 RDIMM modules; the board runs eight-channel DDR5 at up to 5600 MT/s across its 16 slots.

What does the 350 W TDP rating mean for my CPU cooler choice?

The socket supports a single processor with a thermal design power up to 350 W, so choose a cooler rated for at least that heat load.

How many Gen5 NVMe drives can the MCIO connectors run simultaneously?

Two MCIO 8i connectors each provide a PCIe 5.0 x8 link, giving four Gen5 NVMe drives at full x4 bandwidth.
