Server Memory Kit for Supermicro X14SDV-36C-SP3F

This 256GB kit contains two 128GB DDR5 RDIMM modules built for the Supermicro X14SDV-36C-SP3F motherboard. It targets administrators who need to populate every slot with registered ECC memory that the platform recognises at full capacity.

Registered 4Rx4 ECC at DDR5 6400 CL52

Each module is a 288-pin Registered DIMM running at DDR5 6400 (PC5-51200) with CL52 latency and 1.1V operation. The 4Rx4 organisation and registered buffer match the board's memory-controller requirements so the system boots at rated speed without down-clocking.

Low-Voltage Operation and Thermal Profile

At 1.1V the modules draw minimal power for their density, keeping heat output low inside a fully populated server chassis. No heat spreaders are fitted, so airflow across the bare PCBs handles cooling silently in normal rack environments.

Questions about this item

What does the 6400 MT/s speed mean once these modules are installed in the Supermicro X14SDV-36C-SP3F?

The memory controller will run the kit at its rated DDR5 6400 (PC5-51200) data rate, delivering the full 51200 MB/s bandwidth per module when all slots are populated per the board's population rules.

How does the 288-pin RDIMM interface and registered design affect what the motherboard can actually use?

The 288-pin RDIMM form factor with registered architecture is required by this board; it offloads the memory controller so every slot runs fully populated at the rated 6400 speed and 256 GB total capacity.

What physical clearance and slot requirements do the 128 GB 4Rx4 modules need to fit?

Each 288-pin DDR5 RDIMM occupies one standard DIMM slot; the kit includes two modules, so two adjacent slots following the motherboard's population order are required for the full 256 GB upgrade.
