Exact-Match Server Memory Kit

This 256GB kit contains two 128GB DDR5 5600MHz registered ECC RDIMMs built for the Supermicro H13DSG-OM motherboard. Each module runs at 1.1V with CL46 latency and a 2Rx4 rank structure. The registered design buffers address and control signals so the memory controller can drive a fully populated configuration without signal degradation. It is intended for administrators upgrading or servicing that specific platform.

288-Pin Registered ECC Form Factor

The modules use the 288-pin DDR5 RDIMM layout required by the H13DSG-OM and will not fit UDIMM or SODIMM slots. ECC circuitry detects and corrects single-bit errors on the fly, preventing silent data corruption in production workloads. Registered buffering offloads the controller to maintain stability across all populated channels. Buyers who need unbuffered memory or a different pin count cannot use this kit.

256GB Total Capacity Across Two Slots

The dual-module kit delivers 256GB when both DIMMs are installed according to the board's population rules. This density supports large in-memory databases, virtualization hosts, and compute-intensive tasks that benefit from high per-socket memory. Workloads requiring more than 256GB per processor or a different rank configuration will exceed what this kit provides.

Questions about this item

Will the 5600 MT/s rating run at full speed once the two 128 GB modules are installed in my Supermicro H13DSG-OM?

Yes — the kit is spec-matched to the board's memory controller, so it initialises at DDR5-5600 with CL46 timings and 1.10 V across both slots.

What does the PC5-44800 designation cap in real use?

PC5-44800 is the peak transfer rate for DDR5-5600; the registered buffer and ECC logic keep every lane stable at that ceiling even with all slots populated.

Do the 288-pin RDIMM modules fit the H13DSG-OM DIMM sockets without adapters?

They slot straight into the board's 288-pin RDIMM sockets; the 2Rx4 rank layout matches the motherboard's population rules exactly.
