64GB DDR5-6400 RDIMM for Supermicro H14DSG-OM

This 64GB DDR5-6400 Registered ECC module is built for the Supermicro H14DSG-OM motherboard. It delivers 64GB of capacity in a single 288-pin RDIMM. The 2Rx4 organisation and 1.1V operating voltage match the board's memory controller requirements exactly. It is intended for servers that need maximum density per slot.

Registered DDR5 population rules limit full-speed

Registered architecture buffers the command and address signals so every slot can be populated without reducing the data rate. The DDR5-6400 (PC5-51200) interface runs at its rated 6400 MT/s when the motherboard's population rules are followed. Mixing ranks or exceeding the approved slots per channel will force the controller to downclock the memory. The board manual defines the supported configurations.

Single-module headroom and density ceiling

One module provides 64GB of ECC-protected capacity, enough for dense virtualisation or in-memory databases on a single channel. Adding further modules scales total memory until the board's maximum supported capacity or slot count is reached. Beyond that limit the system will not recognise the additional memory. No heat spreader is fitted, so airflow must meet the server chassis specification.

Questions about this item

Should I choose the 64GB 2Rx4 module or a different capacity for my Supermicro H14DSG-OM?

The 64GB 2Rx4 DDR5 6400 CL52 1.1V RDIMM is the exact-match upgrade for the Supermicro H14DSG-OM. Check your manual for approved population order and maximum supported capacity before buying.

What does the 6400MHz speed deliver once installed in the server?

The module runs at DDR5 6400 (PC5-51200) with CL52 latency at 1.1V. Registered buffering lets every slot operate fully populated at rated speed while ECC corrects single-bit errors on the fly.

How does the 288-pin RDIMM interface limit what I can install?

The board requires 288-pin Registered DDR5 RDIMMs; UDIMM or SODIMM modules will not fit or function. The registered architecture offloads the memory controller so all slots can run fully populated.
