64GB DDR5-4800 ECC RDIMM for Supermicro H14DSH

This 64GB DDR5-4800 (PC5-38400) registered ECC module is built for the Supermicro H14DSH motherboard. It runs at 1.1V with CL40 latency and a 2Rx4 rank layout. The 288-pin RDIMM form factor matches the board's registered memory requirement exactly.

Check manual for population rules

Server memory support varies by model and BIOS revision. Consult the Supermicro H14DSH manual for approved DIMM population order, maximum capacity per slot, and total system limits before ordering. Verify that the board accepts 2Rx4 registered modules at the rated speed and voltage.

No heat spreader; lifetime warranty

The module ships without a heat spreader, relying on server chassis airflow for cooling. The package includes the single 64GB RDIMM. A lifetime replacement warranty and free US-based technical support cover the part after installation.

Questions about this item

Does the 64 GB DDR5 4800 MHz CL40 RDIMM arrive as a single module or a kit, and is anything else required for installation?

The package contains one 64 GB DDR5 4800 MHz PC5-38400 2Rx4 1.1 V CL40 288-pin ECC registered RDIMM. No additional parts are needed; the module plugs directly into a compatible Supermicro H14DSH DIMM slot.

Should I choose the 64 GB 2Rx4 CL40 version or a different capacity or rank for the H14DSH?

This 64 GB 2Rx4 CL40 module matches the exact rank, voltage and timing the H14DSH memory controller expects. Other capacities or ranks may not be recognised at full speed or capacity.

What does the 4800 MHz PC5-38400 rating mean once the module is installed in the server?

The module will run at DDR5 4800 MT/s with CL40 latency at 1.1 V, delivering the full PC5-38400 bandwidth the H14DSH platform specifies for registered ECC memory.
