What Does the Corsair ValueSelect DDR4 2133 C15 1x4GB Benchmark Score Mean?

The Corsair ValueSelect DDR4 2133 C15 1x4GB earns a score of 37/100 on our memory performance index, placing it at rank #128 out of 131 tested kits. The score aggregates real-world read/write throughput, memory latency, and gaming frame-rate data across 1,245 user-submitted benchmark samples as of 2026.

This is a budget or older-generation kit. It may create a memory bottleneck in modern games and CPU-intensive applications. An upgrade to DDR5 would significantly improve system responsiveness.

XMP / EXPO: Always enable XMP (Intel) or EXPO (AMD) in your BIOS to run this kit at its advertised speed. Without XMP/EXPO, most DDR5 kits will default to 4800 MHz and DDR4 kits to 2133 MHz regardless of the rated spec printed on the label.

Dual-channel matters: Running two sticks in the correct slots (typically A2 + B2) doubles your memory bus bandwidth compared to single-channel operation, translating to 10–30% higher FPS in CPU-bound titles like Cyberpunk 2077, Starfield, or Microsoft Flight Simulator.
