Isn't a single channel slower than a double channel and will give less fps? null

Dual-channel memory effectively doubles the communication pathway between your CPU and your RAM .

Single Channel: Uses one 64-bit data pathway. Think of it as a single-lane road for all data transfer.

Dual Channel: Uses two 64-bit data pathways simultaneously, creating a combined 128-bit bus. This is like turning that single-lane road into a two-lane highway, allowing the CPU to access twice as much data at once.

The Most Important Performance Impact

The loss isn't just in average FPS, but also in frametime consistency (the time it takes to render individual frames).

CPU Bottleneck: When using single-channel RAM, the CPU often has to wait for data from the slower memory pipeline. This waiting time is called a memory bottleneck.

Stuttering (1% Lows): This bottleneck primarily affects your 1% Low FPS (the minimum frame rates during action). A lower 1% Low FPS translates directly into noticeable stuttering and jarring performance drops, even if your average FPS looks decent. Dual-channel RAM dramatically stabilizes these low frame rates, resulting in much smoother gameplay.

For a smoother, more reliable gaming experience, using a matched pair of RAM sticks in dual-channel configuration is considered a non-negotiable requirement for modern gaming PCs.
