  • 288-pin RDIMM form factor fits the Supermicro H13DSG-O-CPU-D without adapters

Exact-match 1 TB DDR5 kit

This NEMIX RAM kit delivers 1 TB of DDR5 4800 memory as eight 128 GB Registered ECC RDIMMs. It is built for the Supermicro H13DSG-O-CPU-D motherboard and matches the board's required rank, voltage and timing for full-capacity operation. System integrators and administrators upgrading that specific platform receive the precise module specification the memory controller expects.

Registered RDIMM build for full population

Each module uses a 288-pin Registered RDIMM form factor with on-die ECC and a 2Rx4 organisation. The registered architecture buffers address and command signals so every slot can be populated without loading the memory controller. No heat spreader is fitted, allowing the modules to sit in dense server chassis where airflow is managed by the system fans.

DDR5 4800 CL40 at 1.1 V

The kit runs at DDR5 4800 (PC5-38400) with a CAS latency of 40 at 1.1 V. This single speed-grade-and-voltage combination is what the target motherboard validates; boards that require a different DDR5 data rate or a lower CL value will not support this kit at its rated specification.

Questions about this item

Does the DDR5 4800 interface run at its full 4800 MT/s when all eight slots are populated?

Yes, the registered DDR5 4800 modules are designed so the memory controller recognises the full 1 TB kit at the rated 4800 MT/s speed when every slot is filled.

Will these 288-pin RDIMMs fit the Supermicro H13DSG-O-CPU-D motherboard without clearance issues?

The 288-pin RDIMM form factor matches the board's DIMM slots exactly; no heat spreader is present, so standard server chassis clearance applies.

What is the correct population order for the eight 128 GB modules on this board?

Consult the Supermicro H13DSG-O-CPU-D manual for the approved DIMM population sequence before installing all eight modules.
