Speed 4800MHz

  • 48GB capacity lets you run large workloads in a single module
  • DDR5 4800 speed with CL40 timing delivers rated server performance
  • Registered ECC architecture corrects errors and supports full population
  • 1V operation matches the board's memory controller specification
  • Verified fit for Supermicro H13SVW-NT with 288-pin RDIMM form factor

Exact-match DDR5-4800 upgrade

This 48 GB DDR5-4800 registered ECC module is built to the precise rank, voltage and timing the Supermicro H13SVW-NT motherboard expects. It installs as a direct replacement or capacity increase for servers that require 288-pin RDIMM memory.

Fits registered DIMM slots

The 2Rx8 registered architecture offloads the memory controller so every populated slot runs at the rated 4800 MT/s speed without signal degradation. ECC circuitry corrects single-bit errors on the fly to prevent silent data corruption.

Handles 48 GB per module

Each stick delivers 48 GB at CL40 and 1.10 V, giving dense capacity for virtualisation or database workloads. Systems limited to lower maximum DIMM densities or requiring unbuffered UDIMMs cannot use this module.

Questions about this item

Will the 48GB DDR5 4800 CL40 2Rx8 ECC RDIMM run at its rated speed continuously without throttling?

The module operates at 1.10V with CL40 latency and 4800 MT/s. As a registered ECC RDIMM, it buffers address and command signals so the memory controller can sustain full population at rated frequency without downclocking.

What thermal or acoustic impact should I expect from modules without a heat spreader running continuously?

These modules have no heat spreader and draw 1.10V at 4800 MT/s. Registered ECC RDIMMs typically run cool enough for passive airflow in a server chassis; they add no moving parts and produce no audible noise.

What motherboard and population rules must I already satisfy for this 288-pin RDIMM to be recognised?

You need a Supermicro H13SVW-NT motherboard with DDR5 RDIMM slots. The board's manual dictates supported capacities per slot, approved population order, and any BIOS version required for 48GB 2Rx8 modules.
