G.SKILL G5 Series 384GB DDR5 RDIMM Kit
This G.SKILL G5 Series kit provides 384GB of DDR5 registered ECC memory across eight 48GB modules. It is built for workstations based on Intel Xeon W-3400X series processors that require high-capacity, error-correcting memory for memory-intensive workloads such as content creation and rendering.
Verify Intel W790 Motherboard
Before ordering, confirm your motherboard uses the Intel W790 chipset and exposes eight DDR5 channels populated by 288-pin RDIMM slots. The kit relies on Intel XMP 3.0 profiles to reach DDR5 6400 speeds, so the BIOS must support XMP 3.0 and the CPU integrated memory controller must be capable of the rated frequency.
Sustained Load Behaviour at 1.40V CL32
Under sustained load the modules operate at 1.40V with CL32-39-39-102 timings, delivering PC5 51200 bandwidth while on-die and side-band ECC protect data integrity. A dedicated temperature sensor allows the platform to monitor thermals continuously, and hand-screened ICs are tested for stability during extended rendering or compute sessions.

Questions about this item
Does the 384GB kit ship as eight separate 48GB modules or must I buy extra sticks?
The kit contains eight 48GB DDR5 RDIMMs for a total of 384GB; nothing else is required.
Should I pick the CL32 6400MHz version or a slower JEDEC kit for my W790 workstation?
Choose this CL32 6400MHz kit when your Xeon W-3400X CPU and W790 motherboard support Intel XMP 3.0 and 8-channel operation.
What does the 6400 (PC5 51200) rating deliver once installed in an octa-channel board?
It provides 6400 MT/s per module across eight channels with 32-39-39-102 timings at 1.40V, giving maximum registered ECC bandwidth.
