Exact-match DDR5 upgrade for Supermicro H14SST-G

This 128 GB DDR5 4800 RDIMM delivers the precise 2Rx4 registered ECC configuration the H14SST-G memory controller expects. It installs in the board's 288-pin slots at 1.1 V and CL40 so the system recognises full capacity and runs at rated speed without manual tuning.

DDR5 4800 registered ECC limits

Registered architecture offloads the controller to allow full-slot population at 4800 MT/s while ECC corrects single-bit errors on the fly. The 2Rx4 organisation and 1.1 V operation are fixed by the DDR5 4800 standard, so the module cannot run at higher speeds or lower latencies than the platform defines.

2Rx4 registered ECC decides fit

The single specification that determines compatibility is the 2Rx4 registered ECC layout. Boards that require UDIMM, SODIMM, unbuffered, non-ECC or a different rank structure will not accept this module; only systems validated for 2Rx4 RDIMM at DDR5 4800 should use it.

この商品に関する質問

Should I choose the 128GB 2Rx4 RDIMM or a different capacity for my Supermicro H14SST-G?

The 128GB 2Rx4 Registered ECC module matches the board's DDR5 4800 spec, 1.10V voltage and CL40 timing. Consult your motherboard manual for supported capacities and the approved population order before deciding.

What does the DDR5 4800 CL40 rating deliver once the module is installed in the server?

The module runs at the rated 4800 MT/s with CL40 latency at 1.10V. Registered buffering lets every slot operate fully populated at that speed, while ECC corrects single-bit errors on the fly to prevent silent data corruption.

Is the 288-pin RDIMM interface the right fit for the H14SST-G and what does it limit in practice?

Yes — the board requires 288-pin DDR5 RDIMMs, not UDIMMs or SODIMMs. The Registered design offloads the memory controller so all slots can run at the full 128GB capacity and 4800 MT/s without signal degradation.
