Exact-Match DDR5 Server Upgrade

This 32GB DDR5-6400 RDIMM is built for the Supermicro X14SDV-36C-SP3F motherboard. It delivers registered ECC memory at the precise 1.1V voltage and CL52 timing the board expects. System administrators upgrading production servers will find the correct rank and density in a single module.

Registered 288-Pin Form Factor

The 288-pin RDIMM fits only motherboards wired for registered DDR5 memory and cannot be used in UDIMM or SODIMM slots. ECC and registered buffering let the memory controller drive every populated slot at full capacity without signal degradation. Buyers needing non-ECC or unbuffered modules for workstations should look elsewhere.

Low-Voltage DDR5 Operation

Running at 1.10V, the module draws less power per gigabyte than previous DDR generations while maintaining 6400 MT/s throughput. The absence of a heat spreader means airflow across the PCB handles cooling in standard server chassis. Systems without forced-air cooling over the DIMM slots may see higher temperatures.

Questions about this item

Does the CL52 latency limit throughput when the module runs at DDR5-6400 continuously?

The module is rated CL52 at DDR5-6400, and the registered architecture lets the memory controller maintain that timing across all populated slots without down-clocking.

How much heat and power does the 1.1 V registered DIMM produce during all-day operation?

At 1.1 V the DIMM draws minimal power and runs without a heat spreader, so thermal output stays low even in fully populated server configurations.

What motherboard and memory population rules must already be in place for this RDIMM to work?

A Supermicro X14SDV-36C-SP3F motherboard with DDR5 RDIMM slots and the correct population order from the board manual are required.
