Exact-match DDR5 kit for Supermicro H13SVW-N

This 768 GB kit contains six 128 GB DDR5 6400 RDIMMs built to the memory controller's exact rank, voltage and timing expectations. It is intended for administrators upgrading or populating a Supermicro H13SVW-N server that requires registered ECC modules.

Registered ECC design with 288-pin RDIMM form factor

The registered architecture buffers address and command signals so every slot can run fully populated at rated speed, while on-die ECC corrects single-bit errors before they reach applications. Modules operate at 1.1 V with CL52 latency and ship without heat spreaders, matching the board's native DIMM socket requirements.

Replaces partial or lower-capacity DDR5

The kit upgrades systems currently running fewer or smaller RDIMMs to the full 768 GB supported by the validated population rules. The jump is worthwhile when workloads need maximum registered ECC capacity at DDR5 6400 speeds and the motherboard manual confirms the 6 x 128 GB layout.

Questions about this item

Does the DDR5 6400 PC5-51200 interface limit the modules to 6400 MT/s on the Supermicro H13SVW-N?

The kit is rated DDR5 6400 (PC5-51200); the motherboard memory controller will run it at up to that speed when populated according to the board's validated population rules.

Will six 288-pin RDIMM modules fit the Supermicro H13SVW-N motherboard slots?

Yes, the H13SVW-N uses 288-pin DDR5 RDIMM slots; this 6×128 GB kit matches the required form factor and registered architecture for full-slot population.

What is the correct installation order for the six modules on the H13SVW-N?

Follow the motherboard manual's DIMM population sequence — typically filling the primary channel slots first per CPU socket — so the memory controller initialises all 768 GB at the rated 6400 MT/s.
