Server memory kit for Supermicro H14DSG-OM

This 1.5 TB kit contains twelve 128 GB DDR5 registered DIMMs validated for the Supermicro H14DSG-OM motherboard. It targets administrators who need maximum capacity in every slot without mixing modules.

DDR5 RDIMM population limits

The board accepts 288-pin registered DDR5 modules; unbuffered or SODIMM formats will not fit or function. Full 12-slot population requires the exact 2Rx4 rank structure and 1.1 V operation this kit provides.

Capacity headroom and ceiling

Twelve dual-rank modules deliver 1.5 TB at the rated 6400 MT/s CL52, leaving no empty slots for further expansion. Workloads exceeding this capacity would require a platform with higher DIMM counts or larger module densities.

Questions about this item

Should I buy the 1.5TB kit as twelve 128GB modules or choose a different capacity for my Supermicro H14DSG-OM?

The kit is supplied as twelve 128GB modules for a total of 1.5TB. This matches the board's maximum supported capacity per slot and ensures every channel is populated identically for full bandwidth.

What does the 6400MHz rating actually deliver once the modules are installed in the server?

The memory controller will run the kit at DDR5 6400 (PC5 51200) with CL52 latency at 1.1V, giving the rated throughput across all twelve slots when the motherboard is fully populated.

Does the 288-pin RDIMM interface limit the speed or capacity I can reach on this platform?

The 288-pin Registered RDIMM form factor is exactly what the Supermicro H14DSG-OM requires; it supports the full 1.5TB kit at DDR5 6400 without downclocking.
