ADATA XPG Caster RGB AX5U6400C3264G-DCCARBK Review
ADATA XPG Caster RGB AX5U6400C3264G-DCCARBK is a 128GB (2x64GB) DDR5-6400 CL32 kit with 32-39-39-102 timings at 1.4 V, RGB lighting, and XMP 3.0 plus EXPO profiles.
This kit packs 128 GB into just two modules, which keeps the module count at two. At 6400 MT/s and CL32 it has a true latency of 10.0. It runs at 1.4 V. Support for XMP 3.0 and EXPO covers both major platforms. The 64 GB modules need a board that supports them. It is non-ECC.
Performance
Runs natively at 6400MT/s under DDR5 XMP/EXPO profiles, giving a solid bump over JEDEC defaults for top-tier workstation and creative workloads.
Compatibility
Standard 288-pin UDIMM form factor fits any modern DDR5 desktop motherboard with clearance for full-size heatspreaders in most tower coolers.
Use Case
Built for professionals running large simulations, 8K editing timelines, or big VM clusters.
