I want to uprade my pc's ram , but am confused b/w dual chanelled ram with a single stick of4gb ddr3 1200mhz or sinle channeled 2400 ram , does thetwo sticks addup to give 8gb 2400 mhz ?
 
There were some higher Mhz ddr3 modules available, but generally to take advantage of those speeds, you would need to overclock your ram.

The speed of the ram is a different spec than single or dual channeled, which is determined by the motherboard, not the ram. And generally between single and dual channeling, the performance is within 10% of each other.

From what I remember RAM speed with DDR3 had a much smaller impact on performance than RAM speed makes on DDR4 systems. Dual vs single channel still made a significant difference with DDR3.
I think a big part of that is because ddr4 systems expect higher memory speeds and operate slower without it. The most difference I've ever seen someone post about was a max of 10%, and in my own experience I only saw differences in benchmarks and couldn't tell a single thing was different.

And no, RAM speed doesn't stack with multiple sticks. It's more like being handcuffed to a friend. When you're handcuffed to a friend and you both start running, you don't run at the speed of both of you combined, you run at the speed of the slower of the two of you.

This is just a random comparison I found but it is similar to others I have seen. There can be much more than 10% difference but sometimes much smaller. It is very game depending and I expect also depending on the rest of the setup and resolution. A big thing I have noticed with slow RAM is stuttering.
