Exact-match 64 GB DDR5-6400 RDIMM

This NEMIX RAM module delivers 64 GB of DDR5 memory at 6400 MT/s with CL52 latency and 1.10 V operation. It uses a 288-pin registered ECC design built with 4Rx4 organisation for the Supermicro X14SRA-T motherboard.

Registered ECC fit for Supermicro X14SRA-T

The RDIMM form factor matches the board's 288-pin slots and registered architecture, allowing full-capacity population while offloading the memory controller. ECC corrects single-bit errors on the fly to prevent silent data corruption in production workloads.

Low-voltage DDR5 stability

Operating at 1.10 V, the module runs at its rated 6400 MT/s speed without a heat spreader. Registered buffering and ECC maintain signal integrity across fully populated channels for consistent throughput under sustained server loads.

Questions about this item

Does the 4Rx4 rank configuration limit how many of these 64GB modules I can install on the Supermicro X14SRA-T?

The 4Rx4 organization is what the X14SRA-T memory controller expects; the board manual defines the maximum number of ranks per channel and the required population order for full-capacity operation.

How much power and heat does a 64GB DDR5 6400 CL52 RDIMM produce when the server runs continuously?

At 1.10V the module draws minimal power for DDR5-6400; registered buffering reduces electrical load on the controller, so sustained heat output stays low even with every slot populated.

What motherboard slot and firmware support must my Supermicro X14SRA-T already have for this 288-pin RDIMM to work?

The board needs native DDR5 288-pin RDIMM slots and a BIOS that recognises 64GB 4Rx4 registered ECC modules at 6400 MT/s; consult the X14SRA-T manual for the exact population rules.
