Server-Specific 2TB DDR5 Kit

This NEMIX RAM kit delivers 2TB of DDR5 memory in a 16 x 128GB configuration built for the Supermicro H13DSG-O-CPU motherboard. The 288-pin RDIMM modules operate at 4800MHz with CL40 latency and 1.1V power. Registered ECC design ensures data integrity for mission-critical workloads.

Build Integration Requirements

The 288-pin RDIMM form factor fits only motherboards that accept registered DDR5 DIMMs, not UDIMM or SODIMM slots. Fully populating all 16 slots requires the board's memory controller to support this capacity and population order. The 2Rx4 rank structure and 1.1V voltage must match the platform's electrical specification for stable operation.

Capacity and Headroom Limits

Sixteen 128GB modules provide 2TB total capacity for large-scale virtualisation, in-memory databases and high-performance computing. Registered buffering allows full-slot population without signal degradation, while ECC corrects single-bit errors on the fly. Systems needing more than 2TB or faster than DDR5-4800 speeds will require a different platform.

Questions about this item

Will the 2TB DDR5 4800 kit run without throttling in a fully populated Supermicro H13DSG-O-CPU under sustained load?

Registered ECC RDIMM architecture offloads the memory controller so all 16 slots run at the rated 4800 MT/s without downclocking, while ECC corrects single-bit errors on the fly.

How much heat and power does the 16-module kit add when the server runs 24/7?

Each 128 GB module operates at 1.1 V with no heat spreader; total draw scales with the 2Rx4 density, so plan airflow for 16 bare DRAM stacks under continuous load.

What must the Supermicro H13DSG-O-CPU already have for this 288-pin RDIMM kit to be recognised at full 2 TB capacity?

The board needs a DDR5-compatible CPU and BIOS that supports 2Rx4 registered DIMMs populated in the validated slot order; consult the motherboard manual for the exact population sequence.
