Exact-Match 256 GB DDR5 Kit for Supermicro X14SDV

This 256 GB kit contains two 128 GB DDR5-6400 RDIMMs built to the Supermicro X14SDV-36CE-SP3F motherboard's exact specifications. Registered ECC modules with 4Rx4 organisation and CL52 timing operate at 1.10 V so the memory controller recognises full capacity and rated speed immediately. The 288-pin form factor matches the board's DDR5 slots without adapters.

Who Should Choose This and Who Should Not

Server administrators upgrading a Supermicro X14SDV-36CE-SP3F platform to its maximum supported capacity with registered ECC memory will find this kit validated for that board. Builders needing unbuffered UDIMMs, SODIMM modules, lower capacities, or memory for a different motherboard model must select a different product.

Deciding Specification — 4Rx4 Registered ECC

The 4Rx4 registered ECC architecture running at DDR5-6400 (PC5-51200) with CL52 latency is the single parameter that determines compatibility with the X14SDV-36CE-SP3F memory controller. Only modules matching this rank, buffering, error correction, speed, and voltage combination will populate every slot at full capacity and rated frequency.

Questions about this item

Does the 256 GB kit arrive as two 128 GB RDIMMs or do I need extra modules?

The package contains exactly two 128 GB DDR5 RDIMMs, giving the full 256 GB capacity in one kit.

Why choose the 4Rx4 6400 MHz CL52 version instead of a lower-rank alternative?

The 4Rx4 organisation matches the Supermicro X14SDV-36CE-SP3F memory-controller requirements, allowing all slots to run at the rated 6400 MHz with ECC registered operation.

Will the CL52 timing at 1.1 V actually deliver 6400 MT/s in my server?

Yes, the modules are spec-matched to the board's DDR5 6400 (PC5-51200) profile, so the memory controller recognises them at full speed with registered ECC stability.
