Speed 4800MHz

  • 128 GB capacity for memory-intensive workloads using four 32 GB modules
  • DDR5 4800 speed with CL40 latency for rated server performance
  • Registered ECC design corrects single-bit errors and supports full population
  • 1 V operation matches the motherboard memory controller specification
  • Verified compatibility with Supermicro H13SVW-NT motherboard

Exact-match DDR5 kit for Supermicro H13SVW-NT

This 128GB kit delivers four 32GB DDR5 4800 RDIMMs built to the board's precise rank, voltage and timing requirements. Registered ECC architecture offloads the memory controller so every slot runs fully populated at rated speed. The modules arrive new and ready for installation.

Suited for admins expanding a compatible

Builders using a different motherboard, a UDIMM platform or a non-ECC consumer board should look elsewhere. The registered 288-pin form factor and 2Rx8 organisation will not work in desktop sockets or laptop slots. Systems that require lower latency or higher frequencies than CL40 4800 MT/s will not be satisfied.

Four ranks per channel at 1.1V give full 128GB

The kit handles heavily threaded workloads and large in-memory datasets within the board's supported population rules. Headroom ends when the platform's maximum DIMM count or total memory limit is reached, or when an application demands speeds beyond DDR5 4800. Consult the system manual for exact population order before installing.

Questions about this item

Do I need a motherboard with 288-pin DDR5 RDIMM slots to install this 128 GB kit?

Yes, the Supermicro H13SVW-NT provides four 288-pin DDR5 RDIMM slots, which is the exact form factor these 32 GB modules require.

Will the registered 2Rx8 design let me fill all four slots on the H13SVW-NT without downclocking?

The registered architecture buffers the address and command signals, so the memory controller can run all four 2Rx8 modules at the rated DDR5-4800 speed.

How can I confirm the kit is running at CL40 and 1.10 V after installation?

Enter the BIOS or use a hardware utility such as CPU-Z to verify the active timings show CL40 and the DRAM voltage reads 1.10 V.
