G5 Neo Series 128GB Kit

This G.SKILL G5 Neo Series kit provides 128GB of DDR5 registered ECC memory across eight 16GB modules. It is built for AMD workstation platforms that require registered DIMMs and error-correcting code for data integrity. The kit targets professionals running memory-intensive workloads on compatible Threadripper workstations. It is not suited for consumer desktop boards that lack registered memory support or eight-channel architecture.

Capacity and Headroom

The 128GB total capacity handles large datasets, virtualisation clusters and complex rendering scenes with ample headroom. Eight channels of DDR5 6400 bandwidth feed multi-core Threadripper 7000WX processors efficiently. Workloads exceeding 128GB or requiring higher frequencies than the rated 6400 MT/s will hit the kit's fixed limits. Buyers needing more capacity must populate additional channels if the platform allows.

DDR5 6400 EXPO Limits

The modules operate at DDR5 6400 (PC5 51200) with CL32 timings of 32-39-39-102 at 1.40V via AMD EXPO profiles. Stability at this rated speed depends on the motherboard QVL and the CPU integrated memory controller. The registered design adds a clock cycle of buffering, which is mandatory for the WRX90 platform. Systems without EXPO support or WRX90 chipsets cannot utilise the rated overclock profile.

商品問答

Will the 8 x 16 GB DDR5 6400 RDIMMs work alongside my existing DDR5 RDIMMs in a Threadripper 7000WX system?

This kit uses DDR5 6400 RDIMMs with CL32 32-39-39-102 timing at 1.40 V. Mixing modules with different speeds, timings or voltages can prevent the system from training at the rated EXPO profile. For best stability, populate all eight channels with identical modules from the same kit.

How can I verify the kit is running at DDR5 6400 CL32 after installation?

Enter the BIOS and confirm the EXPO profile is enabled. The memory speed should read 6400 MT/s (PC5 51200) with timings 32-39-39-102 at 1.40 V. You can also check the reported speed in the operating system using a tool such as CPU-Z or dmidecode.

What comes in the box and what must be purchased separately?

The package contains eight 16 GB 288-pin DDR5 RDIMM modules for a total of 128 GB. No heat spreaders are included. You must supply a compatible AMD WRX90 motherboard with eight-channel support and a Ryzen Threadripper 7000WX series processor.
