  • 10 V operating voltage reduces power draw under full load
  • 288-pin RDIMM form factor verified for Supermicro H13SVW-NT-OS1 motherboard

Purpose-built server memory kit

This 192 GB kit contains four 48 GB DDR5 RDIMMs built to the exact rank, voltage and timing the Supermicro H13SVW-NT-OS1 motherboard expects. Registered ECC architecture offloads the memory controller so every slot runs fully populated at rated speed while correcting single-bit errors on the fly.

Upgrading from partial or slower configurations

The jump is worth it when your workload needs the full 192 GB at DDR5-4800 without mixing ranks or voltages that force the board to downclock. Systems already running a smaller matched kit at the same 1.1 V CL40 spec will see no benefit beyond the added capacity.

DDR5 RDIMM practical limits

The 288-pin registered form factor only fits motherboards wired for RDIMM; it will not seat in UDIMM or SODIMM slots. Population rules for the H13SVW-NT-OS1 dictate which slots must be filled first, so consult the board manual before installation.

Questions about this item

Will the 288-pin RDIMM modules fit the DIMM slots on a Supermicro H13SVW-NT-OS1 motherboard?

Yes, the 288-pin RDIMM form factor matches the registered DIMM slots required by the Supermicro H13SVW-NT-OS1 motherboard.

What is the correct installation sequence for the four 48 GB modules on this motherboard?

Populate the DIMM slots in the order specified in the Supermicro H13SVW-NT-OS1 manual; the board requires a specific population sequence for registered ECC memory to initialise at full 192 GB capacity.

Do these DDR5 ECC RDIMMs require any firmware updates or periodic maintenance after installation?

No firmware updates are needed for the memory modules themselves; ensure the motherboard BIOS is current so the 4800 MT/s CL40 1.1 V timings are applied correctly.
