Exact-match server upgrade

This 384GB kit delivers four 96GB DDR5 5600 RDIMMs built to the Supermicro H13SSH memory-controller specification. Registered ECC operation with 2Rx4 organisation and 1.1V voltage ensures full-capacity recognition at rated speed without manual tuning.

Replaces partial or mismatched populations

Upgrading from a smaller kit or mixed-rank modules removes the population-rule conflicts that limit usable capacity or force down-clocking. The jump is worth it when the workload demands the full 384GB at 5600MT/s and the board manual confirms 96GB dual-rank support in every slot.

Straightforward 288-pin installation

Modules key into the standard 288-pin RDIMM slots; seat each DIMM until the ejectors click and follow the H13SSH population sequence in the manual. Common issues arise when slots are filled out of order, when a UDIMM is inserted by mistake, or when the BIOS is not updated to the revision that enables 96GB dual-rank density.

Questions about this item

Will the 288-pin RDIMM modules fit the Supermicro H13SSH motherboard DIMM slots?

Yes, the kit uses the 288-pin Registered RDIMM form factor that the H13SSH requires; it is not a UDIMM or SODIMM.

What is the correct population order when installing all four 96GB modules on the H13SSH?

Follow the motherboard manual's approved DIMM population sequence for full-capacity operation; the board's memory-controller rules dictate the exact slot order.

Do these modules have a heat spreader that could need cleaning or replacement over time?

No heat spreader is included on the modules, so no spreader maintenance or replacement is required.
