Exact-fit DDR5 upgrade

This 128 GB kit contains two 64 GB DDR5 5600 modules built for the Supermicro X14SDW-42C-SP9F motherboard. The 288-pin RDIMM form factor and registered architecture match the board's physical and electrical requirements precisely.

Registered ECC constraint

Registered DIMMs add a buffer that reduces electrical load on the memory controller, allowing full population at rated speed. ECC corrects single-bit errors automatically, preventing silent data corruption that can crash production workloads.

CL46 timing at 1.1 V

The kit operates at DDR5 5600 with CAS latency 46 and 1.10 V. If your system requires a different voltage, rank configuration or latency profile, these modules will not be recognised at full capacity or speed.

Questions about this item

Should I choose the 2x64GB kit or a single 128GB module for the Supermicro X14SDW-42C-SP9F?

The Supermicro X14SDW-42C-SP9F requires 288-pin RDIMMs; this kit provides two 64GB modules for dual-channel operation and full 128GB capacity.

What does the DDR5 5600 speed rating deliver when installed in this server board?

The memory runs at 5600 MT/s with CL46 latency at 1.1V, giving the board its rated PC5-44800 bandwidth when all slots are populated.

How does the 288-pin RDIMM interface and ECC registration affect real-world use?

The registered design buffers address and command signals so every slot runs at full 5600 speed, while ECC corrects single-bit errors on the fly.
