Exact-fit server memory upgrade

This 768GB kit contains six 128GB DDR5 5600 ECC registered DIMMs built to the CL46 1.1V 2Rx4 specification your Supermicro H13DSG-O-CPU motherboard expects. Registered architecture and on-die ECC keep every slot stable at full population while correcting single-bit errors before they reach production workloads.

Verify your platform configuration

Server and motherboard memory support varies by model so consult the system or motherboard manual for approved capacities, DIMM population order and installation steps before ordering. The board requires 288-pin registered DIMMs — not UDIMMs or SODIMMs — and the exact rank, voltage and timing this kit provides.

Kit contents and lifetime support

The package delivers the six matched modules as a single tested kit with no heat spreaders included. NEMIX RAM backs the memory with a lifetime replacement warranty and free US-based technical support so you can deploy the upgrade with long-term confidence.

Questions about this item

What does the 768GB kit include and does it need any extra parts to work?

The kit contains six 128GB DDR5 5600 ECC Registered RDIMMs in a single package. No additional components are required; the modules plug directly into the Supermicro H13DSG-O-CPU motherboard's 288-pin slots.

Should I pick this 768GB (6×128GB) DDR5-5600 CL46 kit or a different capacity for the Supermicro H13DSG-O-CPU?

Choose this exact 768GB kit when your board's memory population rules call for six 2Rx4 Registered DIMMs at 1.1V. The part number MR44800-724K6 matches the motherboard's validated configuration for full-capacity operation at DDR5-5600.

What does the DDR5-5600 (PC5-44800) rating mean once the modules are installed in the server?

The memory controller will recognise each 128GB RDIMM at its rated 5600 MT/s transfer rate with CL46 latency and 1.1V operation, enabling all six slots to run fully populated at the specified speed and capacity.
