Exact-match DDR5 6400 ECC RDIMM kit

This 128GB kit contains two 64GB DDR5 6400 (PC5-51200) Registered ECC RDIMMs. Each module runs at 1.1V with CL52 latency and a 4Rx4 organisation. The 288-pin form factor is built for the Supermicro X14SRA-F motherboard and uses major OEM Samsung, Micron or Hynix components.

Check your motherboard manual first

Verify that the X14SRA-F supports 128GB total capacity and the required DIMM population order for 4Rx4 registered modules. Confirm the board accepts DDR5 6400 Registered ECC RDIMMs at 1.1V and that all slots you plan to fill follow the vendor-approved sequence. No heat spreader is included so ensure chassis airflow meets the module specifications.

Ideal for full-population server upgrades

Suits administrators expanding a Supermicro X14SRA-F to maximum registered ECC capacity with matched ranks and voltage. Not for systems that require unbuffered UDIMMs, SODIMMs, non-ECC memory or a different DDR generation. Builders needing lower capacity, different rank structure or consumer-form-factor modules should look elsewhere.

Perguntas sobre este artigo

What is included in the 128GB kit and do I need anything else to install it?

The kit contains two 64GB DDR5 6400 CL52 4Rx4 ECC Registered RDIMM modules, part number MR51200-944K2, 288-pin, 1.10V. No extra parts are required for installation in a compatible Supermicro X14SRA-F motherboard.

Why choose the 2x64GB 4Rx4 DDR5-6400 CL52 kit instead of a different capacity or rank?

This 128GB kit matches the Supermicro X14SRA-F memory population rules for registered ECC RDIMMs at DDR5 6400 (PC5-51200) with 4Rx4 organisation and 1.1V, ensuring full-capacity recognition at rated speed.

What does the DDR5 6400 CL52 rating mean for real-world server performance?

The modules run at 6400 MT/s with CAS latency 52 at 1.10V, providing the bandwidth and error-correcting stability the X14SRA-F memory controller expects when all slots are populated with registered ECC RDIMMs.
