ADATA XPG Caster RGB AX5U6400C4016G-CCARGY Review
ADATA XPG Caster RGB AX5U6400C4016G-CCARGY 16GB single module DDR5-6400 specs price
Sold individually rather than as a kit, this 16GB Caster RGB module runs at DDR5-6400 CL40 and is intended for buyers expanding an existing Caster RGB build or starting a system with a single stick before adding a matching second module.
Comparison to Alternatives
Comparison to Alternatives
- XPG Caster RGB AX5U6400C4016G-DCCARGY, the matched dual-module 32GB kit version of this exact single-stick SKU
- XPG Lancer Blade RGB AX5U6000C3016G-SLABRBK, a single 16GB alternative at a tighter CL30/6000MHz for buyers prioritizing latency over frequency
Single-Stick Purchases for Staged Builds
Buying a single module makes sense when budget or availability calls for a staged upgrade path, but pairing it later with a module from a different production run carries a small risk of mismatched timings; buyers planning a two-stick setup from the start are generally better served by the factory-matched 2x16GB Caster RGB kit.

Expert rating7 / 10
A single-module DDR5-6400 stick that's a natural match for the Caster RGB 2x16GB kit when adding capacity in stages.
Best for
- Single-module capacity additions to an existing Caster RGB system
- Budget SFF builds starting with 16GB and expanding later
- Buyers wanting a matching gray/RGB accent module for a partial upgrade
Not for
- New dual-channel builds (buy the matched 2x16GB kit instead)
- Workloads that need more than 16GB from one module
- Latency-focused builds wanting sub-CL36 timings
