Exact-fit DDR5 ECC RDIMM kit

This 256 GB kit contains two 128 GB DDR5 5600 registered ECC RDIMMs built to the Supermicro X14SDV-36CE-SP3F memory controller specification. Each module runs at 1.1 V with CL46 timing and a 4Rx4 organisation so the board recognises the full capacity at rated speed.

Suited for fully populated server builds

Ideal for administrators populating every slot on the X14SDV-36CE-SP3F with registered ECC memory that corrects single-bit errors and buffers the memory bus. Not for systems that require unbuffered UDIMMs, SODIMM form factors, non-ECC modules or lower-density DIMMs.

Works with the X14SDV-36CE-SP3F population rules

The 288-pin RDIMM form factor matches the board's registered DIMM slots and the kit's rank structure follows the manufacturer's population order. Registered buffering frees the on-die memory controller from electrical load when all channels are filled. ECC operation protects data integrity without extra software overhead.

Questions about this item

What motherboard must I already have for this 256GB DDR5 5600 kit to be recognized at full capacity and rated speed?

The kit is an exact-match upgrade verified for the Supermicro X14SDV-36CE-SP3F motherboard running DDR5 5600 PC5-44800.

How will these 4Rx4 registered ECC RDIMMs behave if I keep older DDR5 modules in the same server?

Registered architecture offloads the memory controller so every slot runs fully populated at full capacity while ECC corrects single-bit errors on the fly.

How can I confirm the kit is running at DDR5 5600 CL46 1.1V after installation?

Check the BIOS or operating-system memory report for 5600 MT/s speed, CL46 latency and 1.10 V voltage on both 128 GB modules.
