Server DDR5 upgrade

This 128GB DDR5 4800MHz registered ECC RDIMM is built for the Supermicro H13SVW-NT-OS2 motherboard. It delivers the exact 2Rx4 rank, 1.1V voltage and CL40 timing the memory controller expects.

Build integration

The 288-pin RDIMM form factor matches the board's registered DIMM slots, not UDIMM or SODIMM sockets. Registered buffering offloads the controller so every populated slot runs at full rated capacity, while ECC corrects single-bit errors on the fly.

Who this suits

Ideal for administrators expanding a verified Supermicro H13SVW-NT-OS2 platform to its maximum supported density with guaranteed compatibility. Builders using consumer boards, unbuffered memory requirements or different DDR generations should look elsewhere.

Questions about this item

How much capacity can a single 2Rx4 RDIMM add to the Supermicro H13SVW-NT-OS2?

Each module provides 128 GB of DDR5 4800 memory, so one DIMM adds the full 128 GB to a compatible slot.

What power draw and thermal load should I expect from this 1.1 V registered ECC kit running continuously?

The DIMMs operate at 1.10 V with no heat spreader; registered buffering reduces controller load, keeping power draw low and thermals manageable in a populated server chassis.

Which motherboard slot type and population rules must my Supermicro H13SVW-NT-OS2 already support for this kit to work?

The board needs 288-pin DDR5 RDIMM slots and must allow 2Rx4 registered ECC modules in the population order shown in its manual.
