ADATA XPG Caster RGB DDR5-6400 Spec and Price in the United Kingdom

DDR52x16GBUDIMM12.50 ns true latency

The Caster RGB reaches the same 6400 MT/s as ADATA's Lancer Blade RGB but settles for CL40 instead of CL32 — a real latency gap between the two lines, not a cosmetic spec difference. The 32GB (2x16) kit still carries RGB lighting, so buyers get the high transfer rate and lit heat spreaders without the tighter binning behind the Lancer Blade's higher position. It fits gamers who want DDR5-6400 bandwidth and RGB but aren't chasing the lowest achievable latency in ADATA's range.

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 kit passed stability testing at its XMP profile and showed strong overclocking potential, reaching DDR5-7000 with added voltage.
  • It needed slightly less voltage than comparable Hynix-based kits at the same overclocked clocks, and the RGB lighting synchronized without trouble on the reviewer's boards.

Commonly criticised

  • The reviewer cautioned that high-frequency DDR5 kits of this class run hot and begin to error above roughly 60 degrees, so serious overclocking needs extra airflow.
