Suggested Answer: C Vote an answer

Comprehensive and Detailed In-Depth Explanation:
Channel configuration(e.g.,dual-channel,quad-channel) determines how memory modules communicate with the memory controller. Usingmatched pairs in dual- or quad-channel setupscan significantlyincrease memory bandwidth, improving performance - especially for gaming and video-intensive tasks.
* Option A (Error correction):ECC RAM is used in servers for reliability, not performance or gaming.
* Option B (RAM voltage):Affects compatibility and overclocking but not bandwidth.
* Option D (Physical size):Refers to module form factor (e.g., DIMM, SO-DIMM) and does not impact bandwidth.
CompTIA A+ Core 1 Exam Objective Reference:
