G.SKILL G5 Series 64GB DDR5 6400 ECC Registered
This quad-channel kit delivers 64GB across four 16GB DDR5 RDIMM modules rated at 6400 MT/s with CL32 timings. It features on-die and side-band ECC plus a dedicated temperature sensor for error correction and thermal monitoring. The modules operate at 1.40V and support Intel XMP 3.0 profiles for configured overclocking. They are built for Intel W790 chipset workstations with Xeon W-2400X series processors.
Suited for multi-channel workstations needing
This kit suits professionals running memory-intensive workloads such as content creation and graphic rendering on compatible Intel W790 platforms. Builders using consumer chipsets, non-Xeon CPUs, or motherboards lacking quad-channel support should look elsewhere. Systems requiring unbuffered UDIMMs or lower voltage operation will not accept these registered modules. The absence of a heat spreader also means airflow must be managed by the chassis.
Sustained load behaviour with registered ECC DDR5
Under continuous heavy workloads the registered buffer helps maintain signal integrity across all four channels while ECC corrects single-bit errors in real time. The onboard temperature sensor allows the platform to monitor thermal status during extended rendering or compute tasks. Stability at the rated 6400 speed depends on motherboard QVL validation and CPU IMC capability over long periods. Hand-screened ICs and factory testing aim to reduce variance during prolonged operation.

Questions about this item
Will this quad-channel DDR5 6400 kit work with my Intel Xeon W-2400X processor?
Yes, the kit is optimised for Intel Xeon W-2400X series processors and requires a compatible Intel W790 chipset motherboard with four-channel memory support.
If I keep my existing DDR5 RDIMMs, can I add this 64GB quad-channel kit alongside them?
Mixing modules with different speeds, timings or voltage is not recommended; this kit runs at DDR5 6400 CL32 1.40V with 32-39-39-102 timings and should be installed as a matched quad-channel set.
How can I confirm the kit is running at its rated DDR5 6400 CL32 speeds after installation?
Enable the Intel XMP 3.0 profile in the BIOS, then verify the operating frequency shows 6400 MT/s and timings read 32-39-39-102 using CPU-Z or the motherboard firmware interface.
