G5 Series 48GB DDR5 RDIMM

This G.SKILL G5 Series module provides 48GB of DDR5 5600 memory in a 288-pin registered DIMM format. It operates at CL46 with 46-45-45-89 timings and a 1.10V voltage. On-die ECC and side-band ECC protect data integrity for server workloads. A dedicated temperature sensor enables thermal monitoring.

Suited for registered ECC platforms

This module fits systems that require registered ECC DDR5 memory with multi-channel support dependent on the motherboard and CPU used. It is not for builds that accept only unbuffered non-ECC UDIMMs or that lack RDIMM support. Buyers needing a heat spreader or lower latency timings should consider other options.

Plug-and-Play support simplifies setup

The module includes plug-and-play support so it can initialise at rated speed without manual configuration. No heat spreader is included, leaving the DRAM exposed for airflow in dense server chassis. The dedicated temperature sensor provides data for platform thermal management. No additional software or accessories are bundled.

Questions about this item

Does this 288-Pin DDR5 RDIMM require a motherboard with an Intel W890 or AMD TRX50 chipset to operate?

The module is validated for Intel W890 series and AMD TRX50 chipsets. A compatible motherboard with DDR5 RDIMM slots and registered ECC support is required for operation.

Can this single 48GB RDIMM be used alongside other DDR5 RDIMMs of different capacities or speeds in a multi-channel setup?

Multi-channel support depends on the motherboard and CPU. Mixing capacities or speeds is not recommended; the system will typically run all modules at the lowest common speed and timing.

How can I verify the on-die ECC and side-band ECC are active after installing this CL46 module?

Check the system BIOS or UEFI memory configuration screen for ECC status reporting, and use operating system tools or hardware monitoring software that reads the dedicated temperature sensor and ECC correction counters.
