Hi
What is Latency Timing and what does 7-7-7-20 mean ?

Basically the timings represent the delay between accessing and transferring data between RAM and the CPU. Generally the lower the latency the better, but there are other factors to consider.

This is of course a very simplified explanation, if you would like a more in depth one then check out the links below.

It's the ram's timings. The lower the better, and the lower the more expensive.

For example DDR3-1600 7-7-7-20 is faster (and more expensive) than DDR3-1600 9-9-9-24.
