Exact-match server memory kit

This NEMIX RAM kit delivers 256GB of DDR5 capacity across four 64GB registered ECC RDIMMs. It is built for the Supermicro H13SVW-N motherboard and runs at 6400MHz with CL52 latency at 1.1V. The 2Rx4 organisation matches the board's memory-controller expectations so the full capacity is recognised at rated speed.

Verified fitment for Supermicro H13SVW-N

The 288-pin registered form factor is the only type this motherboard accepts; UDIMMs or SODIMMs will not work. Population rules for the H13SVW-N require specific slot ordering, so consult the system manual before installation. Registered buffering offloads the memory controller, allowing every slot to run fully populated without down-clocking.

Suited for production servers needing ECC integrity

ECC corrects single-bit errors on the fly, preventing silent data corruption and unplanned reboots in production workloads. Buyers who need unbuffered UDIMMs, lower capacities, or non-ECC modules for consumer platforms should look elsewhere.

Questions about this item

Does this kit use the 288-pin RDIMM form factor required by the Supermicro H13SVW-N motherboard?

Yes, each module is a 288-pin DDR5 RDIMM, matching the registered DIMM slots on the Supermicro H13SVW-N motherboard.

What is the correct installation order for the four 64 GB modules on the Supermicro H13SVW-N?

Install the modules in the sequence specified by the motherboard manual; the board's population rules determine which slots must be filled first for full 256 GB operation.

Will the Samsung, Micron or Hynix DRAM chips on these modules require any firmware updates or periodic replacement?

No, the DRAM chips are standard components that operate without firmware updates and do not have a scheduled replacement interval under normal server use.
