Hello,
I would like to know the exact difference in performances between a dual channel and single channel memory.
Also, is it possible to overclock a single channel memory of 1600MHz.
I remain obliged.

Dual channel memory architectures have two data buses feeding two different sets of memory ranks. This offers double the memory bandwidth when compared to a single memory channel architecture. Large datasets can also be interleaved which reduces the latency.

Synthetic memory benchmarks will show dual channel as performing up to 2x better.
But in actual usage, you would be hard pressed to tell the difference in real application speed.
The reason is that today's cpu chips have excellent memory controllers that can keep the cpu fed with data from any speed ram.

Yes, you might be able to oc some 1600 ram, but to no great effect.
