Exact-match 768GB DDR5 kit

This NEMIX RAM kit delivers 768GB of DDR5 4800 ECC registered memory in a 12-module configuration of 64GB each. It is built for the Supermicro H14SHM motherboard and uses the 288-pin RDIMM form factor that board requires. The modules operate at 1.10V with CL40 latency and a 2Rx4 rank structure.

Registered ECC changes capacity limits

The registered architecture buffers address and command signals so the memory controller can drive all twelve slots at full rated speed without signal degradation. ECC circuitry detects and corrects single-bit errors on the fly, preventing silent data corruption that can crash production workloads. These two features together enable the full 768GB population.

Verify population rules first

Server memory support varies by model and BIOS revision. Check the H14SHM manual for approved DIMM population order, maximum capacity per channel, and any required firmware updates before installing this kit. Incorrect slot placement can leave capacity unrecognised or prevent the system from booting.

Questions sur cet article

How often will the 12 DDR5 RDIMMs need to be replaced in a continuously running server?

The modules are new, have no moving parts, and carry a lifetime replacement warranty, so they only need replacement if a hardware fault develops.

What limits sustained throughput when all 12 slots are populated at 4800 MT/s?

The memory controller on the Supermicro H14SHM manages the 768 GB total capacity and 2Rx4 registered signal integrity, which sets the practical ceiling.

How much heat and power does the 768 GB kit generate at 1.1 V during all-day operation?

Each 64 GB RDIMM runs at 1.1 V with no heat spreader, so total power scales with the 12 modules and the board’s registered buffering overhead.
