256GB DDR5 5600 ECC RDIMM Kit

This 256GB kit contains four 64GB DDR5 5600 registered ECC RDIMMs built for the Supermicro X14SDW-36C-SP9F motherboard. Each module runs at 1.1V with CL46 latency and a 2Rx4 organisation. The registered design lets the memory controller drive a fully populated array at rated speed.

Suited for Supermicro X14SDW-36C-SP9F upgrades

The kit matches the board's DDR5 5600 registered DIMM requirement and its population rules, so all four slots can be filled without downclocking. Builders who need unbuffered UDIMMs, SODIMMs, non-ECC modules, or a different voltage should choose a different product.

Sustained load behaviour with registered ECC

Registered buffering reduces electrical load on the controller during continuous operation, keeping all four modules stable at 5600 MT/s. ECC corrects single-bit errors in real time, preventing silent data corruption during long compute runs. The 1.1V operating voltage limits thermal output under extended workloads.

Questions about this item

What motherboard slot type must my Supermicro X14SDW-36C-SP9F have to accept these 288-pin RDIMMs?

The board must provide DDR5 288-pin RDIMM slots; this kit contains four 64 GB registered ECC modules built for that exact socket.

Can I mix these 2Rx4 CL46 1.1 V modules with other DDR5 RDIMMs of different rank or latency already installed?

Mixing ranks, latencies or voltages is not recommended; the memory controller expects identical 2Rx4 CL46 1.1 V modules in every populated slot for stable operation at 5600 MHz.

How do I confirm the kit is running at the rated 5600 MHz CL46 after installation?

Enter the BIOS or use a hardware utility such as CPU-Z and verify the memory frequency reads 5600 MHz with CAS latency 46 across all four DIMMs.
