Exact-match DDR5 RDIMM for Supermicro

This 48GB DDR5 6400 CL52 2Rx8 1.1V ECC Registered RDIMM is built to the precise rank, voltage and timing the Supermicro H13SVW-N motherboard expects. It installs as a single 288-pin module and runs at its rated PC5-51200 speed when the platform memory controller recognises the configuration.

Check motherboard manual before ordering

Verify the board's supported capacity per slot, approved DIMM population order and any BIOS revision requirements for DDR5 6400 Registered ECC memory. The module uses 2Rx8 organisation and 1.10V operation; confirm these parameters match the system's qualified-vendor list and that all populated slots follow the manufacturer's installation sequence.

Suits single-slot capacity upgrades on H13SVW-N

Administrators adding or replacing memory in a Supermicro H13SVW-N platform gain registered ECC stability with single-bit error correction and buffered signalling for full-slot populations. Builders needing unbuffered UDIMMs, SODIMM form factors, non-ECC modules or speeds other than DDR5 6400 should select a different part.

Questions about this item

What comes in the box and is anything else needed for installation?

The package contains one 48GB DDR5 6400 CL52 2Rx8 1.1V ECC Registered RDIMM. No additional parts are required; install directly into a compatible 288-pin DDR5 RDIMM slot.

Should I choose this 48GB module or a different capacity for my Supermicro H13SVW-N?

This 48GB RDIMM matches the board's qualified 2Rx8 registered ECC specification at 6400 speed. Check your motherboard manual for supported capacities and population order before selecting.

What does the 6400 speed rating mean once the module is installed in the server?

The module runs at DDR5 6400 (PC5-51200) with CL52 latency at 1.1V when the memory controller is configured for that speed, delivering the rated bandwidth in a fully populated registered configuration.
