  • 288-pin RDIMM form factor fits the Supermicro H13DSG-O-CPU-D motherboard

Exact-match server upgrade

This 768GB kit contains six 128GB DDR5 4800 RDIMM modules built to the Supermicro H13DSG-O-CPU-D motherboard's specifications. Each module runs at 1.1V with CL40 timing and 2Rx4 registered ECC architecture. The kit delivers the precise rank, voltage and timing the memory controller expects for full-capacity recognition at rated speed.

Enterprise workloads not consumer builds

Suited for administrators populating every slot on a supported Supermicro server where registered ECC stability and maximum capacity are required. Not suited for workstations or desktops that accept only unbuffered UDIMMs, nor for systems limited to lower densities or slower DDR5 speeds. Buyers needing SODIMM form factors or non-ECC memory should look elsewhere.

Six-slot population at full speed

The 288-pin registered design offloads the memory controller so all six slots operate at DDR5 4800 without signal degradation. ECC corrects single-bit errors on the fly to prevent silent data corruption in production. Verify your motherboard manual for approved population order and maximum supported capacity before installation. No heat spreaders are included.

Questions about this item

Does the Supermicro H13DSG-O-CPU-D motherboard need to be present for this 768GB kit to function?

Yes, this 6 x 128GB DDR5 4800 RDIMM kit is built specifically for the Supermicro H13DSG-O-CPU-D motherboard and requires that board's 288-pin registered DIMM slots to operate.

Can I mix these 2Rx4 DDR5 4800 CL40 modules with any existing RDIMMs already installed in the system?

Mixing ranks, speeds or latencies is not recommended; the motherboard's memory controller expects identical 2Rx4 DDR5 4800 CL40 1.1V modules in every populated slot for stable operation.

How can I verify the full 768GB is recognised and running at DDR5 4800 after installation?

Check the BIOS memory information screen or the operating system's memory report — both should show 768GB total capacity and a running speed of 4800 MT/s with CL40 timings.
