Exact-match DDR5 kit for Supermicro H13SVW-N

This 256 GB kit contains two 128 GB DDR5-6400 registered ECC RDIMMs built to the precise rank, voltage and timing the motherboard expects. The modules operate at 1.1 V with CL52 latency and a 2Rx4 organisation so the server recognises the full capacity at rated speed.

Verified fitment and registered ECC stability

The 288-pin RDIMM form factor matches the board's memory population rules and is not interchangeable with UDIMM or SODIMM. Registered architecture offloads the memory controller for reliable operation when every slot is populated, while on-die ECC corrects single-bit errors to prevent silent data corruption and unexpected reboots.

Suits Supermicro H13SVW-N upgrades needing maximum

Builders expanding a compatible Supermicro H13SVW-N platform to 256 GB with registered ECC modules will find the spec-matched kit installs without guesswork. Systems that require unbuffered UDIMMs, SODIMM form factors, non-ECC memory or a different DDR generation cannot use these modules.

Questions about this item

Will the Samsung, Micron or Hynix chips on these RDIMMs need replacement under normal server workloads?

The modules use major OEM chips from Samsung, Micron or Hynix and carry a lifetime replacement warranty, so no chip-level maintenance is expected.

What thermal or power limit appears first when the kit runs at DDR5-6400 continuously?

Each DIMM operates at 1.10 V with no heat spreader; sustained loads are limited by the registered buffer and the motherboard's airflow design.

How much fan noise or extra heat should I expect from the 256 GB kit running all day?

The 1.1 V RDIMMs have no heat spreader, so case fans must move enough air across the 288-pin slots to keep temperatures in spec.
