128GB DDR5 ECC RDIMM Kit

This NEMIX RAM kit delivers 128GB of DDR5 ECC registered memory in a matched pair of 64GB modules. It operates at 6400MHz with a CAS latency of CL52 and runs at the standard DDR5 voltage of 1.10V. The modules use a 288-pin RDIMM form factor with a 4Rx4 rank configuration built from major OEM DRAM chips.

For Supermicro X14SBW-F Servers

This memory is validated for the Supermicro X14SBW-F platform and similar systems that require DDR5 ECC RDIMM modules. It is not suitable for desktop motherboards that accept only unbuffered UDIMM memory or for laptops and small-form-factor boards that use SO-DIMM slots. Buyers needing non-ECC or unregistered modules should look elsewhere.

DDR5 6400MHz Registered ECC Specification

The decisive specification is the DDR5 6400MHz registered ECC RDIMM standard with 4Rx4 organisation. Only systems whose memory controller and BIOS support this exact combination of speed, voltage, rank geometry and error correction will recognise and run the kit at its rated 6400MHz data rate.

Questions about this item

How can I confirm the 6400MHz DDR5 ECC RDIMM kit is running at the correct speed after installation?

Enter the system BIOS or UEFI and verify the memory frequency reads 6400MHz with CL52 latency and 1.10V voltage on all 128GB.

What exactly is included in the package and do I need any extra brackets or cables?

The box contains the 2x64GB 288-PIN DDR5 RDIMM modules only; no heat spreaders, brackets or cables are supplied or required.

Should I choose the 4Rx4 6400MHz CL52 kit or a different rank and latency for my Supermicro X14SBW-F?

The 4Rx4 6400MHz CL52 1.10V specification matches the board's qualified memory list; other ranks or latencies are not validated for this system.
