Supermicro H13SVW-NT DDR5 upgrade

This 128 GB DDR5 registered ECC module is built for the Supermicro H13SVW-NT motherboard. It delivers the exact 288-pin RDIMM form factor, 2Rx4 rank structure, 1.10 V voltage and CL40 timing the board's memory controller expects for full-speed operation.

128 GB capacity and registered headroom

The single DIMM provides 128 GB of addressable memory while the registered architecture buffers address and command signals so the controller stays stable when every slot is populated. ECC corrects single-bit errors on the fly, preventing silent data corruption in production workloads. Systems that require unbuffered UDIMMs or SODIMMs cannot use this module.

CL40 latency at DDR5-4800 decides fit

The module runs at 4800 MT/s (PC5-38400) with a CAS latency of 40 cycles. If your server's qualified-vendor list specifies a different latency or speed bin, the memory controller may downclock the DIMM or refuse to boot. Verify the exact CL40 requirement in your system manual before ordering.

Questions about this item

Will this 128GB DDR5 4800 CL40 2Rx4 ECC RDIMM work in my Supermicro H13SVW-NT motherboard alongside existing DDR5 modules?

This module is spec-matched to the Supermicro H13SVW-NT memory controller with 1.1V operation, CL40 timing, and 2Rx4 registered architecture. For mixed populations, consult your motherboard manual for approved DIMM population order and supported capacity configurations.

How can I verify the 128GB DDR5 4800 CL40 ECC RDIMM is running at its rated 4800MHz speed after installation?

Enter the system BIOS or UEFI and check the memory information screen. It should report DDR5 4800 (PC5-38400), CL40 latency, 1.10V voltage, and 128GB total capacity with ECC active.

Does the 128GB DDR5 4800 CL40 2Rx4 ECC RDIMM kit include a heat spreader or any installation tools?

The package contains the 128GB DDR5 4800MHz PC5-38400 2Rx4 1.1V CL40 288-pin ECC Registered RDIMM only. No heat spreader or tools are included; the module uses bare chips and installs directly into the 288-pin RDIMM slots.
