256GB DDR5 5600 ECC RDIMM kit

This 256GB kit contains four 64GB DDR5 5600 registered ECC DIMMs built for the Supermicro H14SSF motherboard. Each module runs at 1.1V with CL46 latency and a 2Rx4 organisation. The registered design allows full population of every slot on this platform.

Capacity and headroom

Four ranks per channel give the memory controller the density it expects for 256GB operation at rated speed. Workloads that fit within this footprint run with ECC protection and no downclocking. Applications needing more than 256GB per board must use a platform that supports larger DIMMs or additional channels.

DDR5 288-pin RDIMM limits

The 288-pin registered form factor is mandatory for this motherboard; unbuffered or SO-DIMM modules will not fit or function. DDR5 5600 (PC5-44800) is the maximum JEDEC speed this kit guarantees; overclocking or mixing speeds is not supported by the server memory controller.

Questions about this item

Will the 256GB kit (4 x 64GB) run at DDR5 5600 on my Supermicro H14SSF alongside existing DDR5 RDIMMs?

The kit is spec-matched to the H14SSF memory controller at 5600 MT/s, CL46, 1.1 V, 2Rx4 registered ECC; match rank, voltage and timing in the remaining slots for stable operation.

How can I verify the 288-pin RDIMMs are recognised at full 256GB capacity after installation?

Check the BIOS memory map or OS reporting (e.g., dmidecode) — all four 64 GB modules should appear at DDR5 5600 with ECC enabled and no correctable-error spikes.

What ships in the 256GB kit and do I need any extra parts for the H14SSF?

The box contains four 64 GB DDR5 5600 CL46 1.1 V 288-pin ECC RDIMMs; no cables, brackets or additional components are required for the H14SSF DIMM slots.
