512GB DDR5-5600 ECC RDIMM Kit

This 512GB kit contains four 128GB DDR5-5600 Registered ECC RDIMMs built for the Supermicro H13SSF motherboard. It targets administrators who need maximum registered capacity on that specific platform. Each module runs at 1.1V with CL46 timing and a 2Rx4 rank structure.

Verify Motherboard Population Rules

Before ordering, check the Supermicro H13SSF manual for approved DIMM population order and supported capacities per slot. The board requires 288-pin Registered RDIMMs; UDIMM or SODIMM modules will not fit or function. Confirm your BIOS revision supports the full 512GB configuration.

Lifetime Replacement and US Support

The kit includes a lifetime replacement warranty and free US-based technical support. These services provide direct assistance if a module fails or if you need guidance during installation on the qualified Supermicro platform.

Questions about this item

Does the kit include all four 128 GB modules, or do I need to buy extra DIMMs?

The package contains the complete 512 GB kit — four 128 GB DDR5 5600 RDIMMs — so no additional modules are required.

I see only one capacity listed; is there any other version of this kit I should consider?

This part number MR44800-724K4 is offered solely as a 512 GB (4 × 128 GB) kit; no alternative capacities or speed grades exist for this model.

Will the CL46 latency at DDR5 5600 actually run at that speed once installed in my Supermicro H13SSF?

Yes — the modules are spec-matched to the board's memory controller, so the kit is recognised at full capacity and operates at the rated 5600 MT/s with CL46 timing.
