Capacity and purpose

This 768 GB DDR5 kit contains eight 96 GB registered ECC RDIMMs built for the Supermicro H13DSG-OM motherboard. It targets servers that need maximum memory capacity per slot and full population without downclocking. Buyers who need unbuffered UDIMMs or non-ECC modules cannot use this kit.

Thermals and power

Each module runs at 1.10 V with a CL52 latency at DDR5-6400 speed. The registered design reduces electrical load on the memory controller when all eight slots are filled, helping maintain stable operation under sustained workloads. No heat spreaders are fitted, so chassis airflow must be sufficient for bare modules.

Build integration

The 288-pin RDIMM form factor matches the board's slot requirements exactly; UDIMM or SODIMM alternatives will not seat. Population order and maximum supported capacity per slot are defined in the motherboard manual and must be followed. This kit frees all other expansion resources by satisfying memory needs in a single validated configuration.

Questions about this item

How do I install the 8x96GB RDIMM kit into the Supermicro H13DSG-OM, and which slot population order do people often get wrong?

Install the eight 288-pin RDIMM modules following the motherboard manual's specific population sequence for full 768GB capacity; the common mistake is ignoring the required order for registered ECC DIMMs, which prevents the system from recognising all modules at the rated DDR5 6400 speed.

What maintenance or replacement will the registered ECC RDIMM kit need during its service life?

The modules have no heat spreaders and require no scheduled maintenance; ECC corrects single-bit errors automatically, and if a module fails the lifetime replacement warranty covers a direct swap without servicing the board.

What is the first limit that appears when the 768GB kit runs sustained workloads at CL52?

The primary limit is the fixed CAS latency of 52 cycles at 1.10V; under continuous load the registered buffer and 2Rx4 organisation maintain stability, but latency cannot be reduced beyond the specified CL52 timing.
