Exact-fit DDR5-5600 RDIMM kit for Supermicro H14SSF

This 768GB kit contains six 128GB registered ECC modules built to the DDR5-5600 (PC5-44800) standard. It targets administrators and integrators who need the full 768GB capacity on a Supermicro H14SSF motherboard without mixing ranks or voltages.

Registered DDR5 at 1.1V runs every slot at rated

The 2Rx4 registered architecture buffers address and command signals so the memory controller can drive all six slots at 5600 MT/s with CL46 timing. ECC corrects single-bit errors on the fly, preventing silent data corruption in production workloads. The 1.1V operating voltage matches the board's DDR5 specification exactly.

Replaces partial or mixed-capacity populations

Moving from a partially populated or mixed-rank configuration to this uniform 6×128GB kit eliminates population-rule conflicts and lets the server address the full 768GB at the rated data rate. The jump is worth it when the workload demands maximum registered ECC capacity on this specific platform.

Questions about this item

How do I choose the right capacity kit for my Supermicro H14SSF?

This kit provides 768GB using six 128GB modules, matching the board's DDR5 RDIMM slot count and population rules for full-capacity operation.

What does DDR5 5600 CL46 mean for real-world server performance?

The modules run at DDR5 5600 with CL46 latency and 1.1V, giving the memory controller the exact timing and voltage it expects for stable, full-speed operation.

Will the 288-pin RDIMM interface work with my H14SSF motherboard?

Yes, the 288-pin Registered ECC RDIMM form factor is the one the H14SSF requires; it is not compatible with UDIMM or SODIMM slots.
