Exact-fit DDR5 ECC RDIMM kit

This NEMIX RAM kit delivers 128 GB as two 64 GB DDR5-5600 registered ECC modules. Each DIMM runs at 1.1 V with CL46 latency and a 2Rx4 rank structure. The 288-pin RDIMM form factor matches the Supermicro X14SDW-36C-SP9F motherboard's memory controller expectations for full-capacity operation.

Verify board rules before ordering

Confirm the motherboard manual for approved DIMM population order and maximum supported capacity per channel. Ensure the system requires registered ECC RDIMMs rather than unbuffered UDIMMs or SODIMMs. Check that the BIOS version installed recognises the specified rank and voltage configuration for stable POST.

Replaces mixed or lower-capacity kits

The jump is worth it when moving from smaller registered ECC sets or mismatched speeds that force down-clocking. It also upgrades non-ECC or unbuffered memory that lacks error correction and controller buffering. Builders needing consumer UDIMMs or higher-frequency modules without ECC should look elsewhere.

Questions about this item

What comes in the 128GB kit and is anything else needed to install it in a Supermicro X14SDW-36C-SP9F?

The kit contains two 64GB DDR5 5600 CL46 1.1V 288-pin ECC Registered RDIMM modules. No extra parts are required; the DIMMs plug directly into the motherboard's DDR5 RDIMM slots.

Why choose the 2x64GB 2Rx4 CL46 version instead of a different capacity or rank?

This exact 2Rx4 Registered ECC configuration matches the Supermicro X14SDW-36C-SP9F memory controller requirements, allowing full 128GB capacity at the rated DDR5 5600 speed without down-clocking.

What does the DDR5 5600 (PC5-44800) rating deliver once the modules are seated in the server?

The modules run at 5600 MT/s with CL46 latency at 1.1V, providing the bandwidth and error-correction the X14SDW-36C-SP9F expects for stable, full-capacity operation.
