Exact-match DDR5 RDIMM for Supermicro H14SST-G

This 96 GB DDR5-4800 registered ECC module is built to the precise rank, voltage and timing the Supermicro H14SST-G memory controller expects. The 2Rx4 organisation and 1.1 V operation let the board recognise full capacity at rated speed without manual tuning. It is intended for administrators who need a validated, single-part-number upgrade for this specific platform.

Sustained enterprise stability

Registered buffering offloads the memory controller so every slot can run fully populated at 4800 MT/s continuously, while on-die ECC corrects single-bit errors in real time. The CL40 latency and major-brand DRAM chips maintain throughput under long-running workloads such as virtualisation hosts or database servers without the throttling seen on unbuffered alternatives.

Replaces mismatched or capacity-limited DIMMs

The kit upgrades systems currently running lower-density RDIMMs or mixed-rank configurations that force the controller to down-clock. The jump is worthwhile when the motherboard manual confirms support for 96 GB 2Rx4 registered modules and the population rules allow the target slot count. It does not fit boards that require UDIMM, SODIMM or non-ECC memory.

Questions about this item

How much power does this 96GB DDR5-4800 CL40 2Rx4 kit draw at its rated 1.1V when the server runs continuously?

Each module operates at 1.10V, the standard DDR5 voltage, so power draw scales with the 96GB capacity and 4800 MT/s data rate; registered buffering reduces electrical load on the memory controller during sustained workloads.

What must the Supermicro H14SST-G motherboard provide for this 288-pin RDIMM kit to be recognised at full 96GB capacity?

The board needs DDR5 RDIMM slots wired for registered ECC memory, a memory controller that supports 2Rx4 organisation at 4800 MT/s, and a population order that allows the installed capacity per channel.

Will this DDR5-4800 CL40 2Rx4 kit run alongside other DDR5 RDIMMs I might still have installed?

Mixing ranks, speeds, or voltages can force the memory controller to downclock all channels to the slowest common settings; the motherboard manual lists approved population rules for stable operation.
