Server DDR5 ECC RDIMM kit

This NEMIX RAM kit delivers 512GB of DDR5 memory across eight 64GB registered DIMMs. It operates at 5600MHz with CL46 latency and 1.1V, matching the exact rank and timing the Supermicro H14SSL-N motherboard expects for full-capacity recognition.

Suited for full-population server builds

The 2Rx4 registered ECC design offloads the memory controller so every slot runs fully populated while correcting single-bit errors on the fly. Builders using UDIMM or SODIMM platforms, or boards that do not support 288-pin RDIMM population rules, should look elsewhere.

Eight matched modules in one kit

The package supplies eight 64GB modules pre-verified for the target motherboard, removing the guesswork of mixing individual sticks. No heat spreaders or extra software are included; the value is the spec-matched kit itself.

Questions about this item

Does the Supermicro H14SSL-N motherboard need to support DDR5 5600 RDIMMs for this 512GB kit to function?

Yes, the board must accept DDR5 5600 registered ECC RDIMMs at 1.1V with 2Rx4 organization and CL46 timing; otherwise the modules will not be recognized or will run at reduced speed.

Can I mix these 64GB 2Rx4 DDR5 5600 RDIMMs with smaller-capacity DDR5 RDIMMs already installed in the H14SSL-N?

Mixing is only reliable when every installed DIMM matches the same DDR5 5600 speed, 1.1V voltage, registered ECC type, and 2Rx4 rank structure; otherwise the memory controller will down-clock or halt training.

How can I confirm the full 512GB is running at DDR5 5600 with ECC active after installation?

Enter the server BIOS or use a hardware inventory tool such as dmidecode to verify all eight slots show 64GB each, speed reads 5600 MT/s (PC5-44800), voltage 1.1V, and ECC status reports enabled.
