Exact-match DDR5 512 GB kit for Supermicro X14SRA-T

This NEMIX RAM kit supplies 512 GB across eight 64 GB DDR5 RDIMMs rated at 6400 MT/s with CL52 latency and 1.1 V operation. The 4Rx4 registered ECC modules are built to the precise rank, voltage and timing the server's memory controller expects for full-capacity recognition at rated speed.

Verify motherboard population rules before ordering

Server and motherboard memory support varies by model so consult the system or motherboard manual for supported capacities, approved DIMM population order and installation steps. The board requires 288-pin registered RDIMMs, not UDIMM or SODIMM, and this kit matches that form factor exactly.

Registered ECC architecture maintains stability

Registered buffering offloads the memory controller allowing every slot to run fully populated at full capacity while ECC corrects single-bit errors on the fly to prevent silent data corruption and unplanned reboots. Modules operate at the specified 1.1 V without a heat spreader.

Questions about this item

Does the 512GB kit ship as eight individual 64GB modules or do I need to order them separately?

The kit contains eight 64GB DDR5 RDIMMs pre-matched for the Supermicro X14SRA-T; no extra modules are required.

Should I choose the 4Rx4 CL52 1.1V variant or a different rank and latency for this motherboard?

The X14SRA-T memory controller expects 4Rx4 registered ECC at 1.1V and CL52; this exact specification ensures full-speed recognition across all slots.

Will the DDR5 6400 rating actually run at 6400 MT/s once installed in the Supermicro X14SRA-T?

Yes — the modules are spec-matched to the board's DDR5 6400 (PC5-51200) profile so the memory controller trains them at the rated 6400 MT/s when populated per the manual.
