What owners and reviewers say
Summarised from 1 source(s), reviewed September 14, 2026. A source is counted only where it names this model exactly. How we track prices
Commonly praised
- Reviewers found the 64GB (2x32GB) DDR5-6400 kit fast and stable on an AM5 platform, with both Intel XMP 3.0 and AMD EXPO profiles.
- They rated the build quality highly, singling out the shark-gill ARGB heat spreader and the lifetime warranty.
- Applying the motherboard's EXPO-tweaked preset cut latency and raised memory benchmark scores noticeably over the default profile.
Commonly criticised
- At its rated CL32-39-39-102 profile the kit's latency was noticeably higher than a competing DDR5-6000 kit, and reviewers thought the timings could have been tightened further.
- They cautioned that tighter timings would need adequate case airflow to remain stable.
