G.SKILL F5-6400R3239G16GQ4-G5 64GB (4×16GB) DDR5 6400 CL32 ECC Registered server RAM

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.
