Exact-match server upgrade

This NEMIX RAM module delivers 16GB of DDR5 4800 registered ECC memory in a 288-pin RDIMM form factor. It operates at 1.1V with CL40 latency and a 1Rx8 rank structure built on major OEM chips. The stick is validated for the Supermicro H13SVW-N motherboard and installs as a single 16GB kit.

Replaces mismatched or slower DIMMs

Swapping out unbuffered UDIMMs, slower DDR5 speeds, or modules with different rank counts eliminates boot failures and timing errors. The registered buffer lets every slot run fully populated at rated speed, while on-die ECC corrects single-bit errors before they corrupt data. Upgrade when your current memory limits capacity or triggers unplanned reboots.

Suits Supermicro H13SVW-N builders

System integrators and administrators who need a guaranteed fit for this specific board will benefit from the verified part number MR38400-618K1. Buyers who want more storage, consumer overclocking features, or non-ECC unbuffered memory should look at something else.

Questions about this item

Will this 288-pin DDR5 RDIMM fit the Supermicro H13SVW-N motherboard slots?

Yes, it is a 288-pin DDR5 RDIMM built to the board's exact population rules for registered ECC memory.

What is the correct way to install this 1Rx8 ECC RDIMM in the Supermicro H13SVW-N?

Follow the motherboard manual's DIMM population order; the registered design offloads the controller so every slot runs fully populated at 4800 MT/s.

When should I expect to replace this 16GB DDR5 4800 module?

It carries a lifetime replacement warranty and has no moving parts or heat spreader to degrade under normal server operation.
