  • 288-pin RDIMM form factor verified for Supermicro H13SST-GC

Kit Composition

This 128GB kit contains four 32GB DDR5 5600 ECC Registered RDIMM modules built for the Supermicro H13SST-GC motherboard. Each stick runs at 1.1V with CL46 latency and a 2Rx8 organisation so the memory controller sees the exact rank and timing it expects. The registered design offloads the controller and allows every slot to be populated at full rated speed without signal degradation.

Installation Notes

Modules are standard 288-pin RDIMMs that insert vertically into the board's DDR5 slots; no heat spreaders are fitted so clearance around tall CPU coolers is maximised. Because the kit is spec-matched to the H13SST-GC population rules, following the manual's recommended slot order will avoid the common issue of the system halting at POST or reporting reduced capacity when all four slots are filled.

Suitability

This kit suits administrators upgrading a Supermicro H13SST-GC server that requires registered ECC memory at DDR5-5600 with 2Rx8 density. It is not intended for workstations or consumer boards that accept only unbuffered UDIMMs, nor for systems needing a different voltage, rank configuration or memory generation than the one specified here.

Questions about this item

How can I confirm the kit is running at DDR5-5600 CL46 after installation?

Enter the BIOS or UEFI and verify the memory frequency reads 5600 MT/s with CAS latency 46; the registered ECC design also lets the OS report corrected-error counts so you can see ECC is active.

What does the MR44800-328K4 kit include and is anything else required?

The box contains four 32 GB 288-pin DDR5 RDIMM modules for a total of 128 GB; no extra cables, brackets or heat spreaders are needed or supplied.

Why choose this 128 GB 4×32 GB kit instead of a different capacity?

This exact 4×32 GB configuration matches the Supermicro H13SST-GC population rules for full-capacity registered ECC operation at 1.1 V, so every slot is filled with the rank and voltage the memory controller expects.
