Exact-match DDR5-5600 ECC RDIMM kit

This 64GB kit contains two 32GB DDR5 5600 registered ECC modules built to the precise rank, voltage and timing the Supermicro H14SSL-N memory controller expects. It is intended for administrators upgrading that specific server platform to its full supported capacity. Buyers needing non-ECC UDIMMs or a different form factor should look elsewhere.

Registered architecture

The registered design buffers address and command signals so every slot can run fully populated at the rated 5600 speed while ECC corrects single-bit errors on the fly. Modules operate at 1.1V without a heat spreader and use the 288-pin RDIMM connector this board requires, not a UDIMM or SODIMM socket. Systems that only accept unbuffered memory cannot use this kit.

Verify manual before ordering

Server memory support varies by model and BIOS revision. Consult the Supermicro H14SSL-N manual for approved DIMM population order, maximum capacity per channel and any required firmware updates before purchase. This kit is validated for that motherboard only; other Supermicro boards or different vendors may have incompatible population rules.

Questions about this item

Does the DDR5 5600 interface cap at PC5-44800 bandwidth?

Yes, the kit runs at DDR5 5600 which equals PC5-44800, so that is the maximum data rate the modules will deliver on this platform.

Will the 288-pin RDIMM form factor fit the Supermicro H14SSL-N DIMM slots?

The board requires 288-pin registered DIMMs; these modules match that exact pin count and registered design, so they seat correctly in every supported slot.

How are the two 32 GB modules installed, and which step is often missed?

Install the pair in the motherboard's prescribed population order — usually the first slot of each channel — and fully seat both modules until the retention clips lock; skipping the manual's slot sequence is the common error.
