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.
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.
