Supermicro H13SVW-NT-OS1 DDR5 upgrade

This 128GB kit contains two 64GB DDR5 4800 CL40 registered ECC RDIMMs built for the Supermicro H13SVW-NT-OS1 motherboard. It targets administrators who need the exact rank, voltage and timing the board expects so every slot is recognised at full capacity.

Registered ECC RDIMM kit

The 2Rx4 registered architecture buffers address and command signals, letting the memory controller drive a fully populated configuration without signal degradation. On-die ECC corrects single-bit errors in flight, preventing silent data corruption and unplanned reboots in production workloads.

DDR5 4800 RDIMM constraints

The modules run at 1.1V with a fixed CL40 latency and 288-pin RDIMM keying, so they only fit DDR5 registered DIMM slots. Population order and maximum supported capacity per slot are defined by the motherboard manual and must be verified before installation.

Questions about this item

Will the 2Rx4 ECC RDIMM modules require any firmware updates or periodic reseating to maintain stability?

No firmware updates or scheduled reseating are needed. The registered ECC design handles error correction automatically, and the modules are validated for continuous operation at the rated 4800 MT/s CL40 1.10 V settings.

What is the first limit reached when the kit runs at full 128 GB capacity under sustained load?

The memory controller's maximum supported frequency of 4800 MT/s is the primary ceiling; the modules are rated CL40 at 1.10 V, so latency and voltage remain fixed at those values during extended use.

How much heat and power does the 2 x 64 GB kit produce when the server runs all day?

Each module operates at 1.10 V without a heat spreader, so total power draw stays low and passive airflow in a standard server chassis is sufficient for continuous 24/7 operation.
