DDR4 is the fourth generation of RAM memory technology for computers. It replaces DDR3 and offers increased speeds and greater capacity than its predecessor.
Specifically, DDR4 offers operating speeds from 2133MT/s to 4800MT/s, latency (CAS Latency) from CL 9 to CL 22, while its capacity has increased up to 16GB per memory module.
For speed (MT/s) and capacity (GB), the more size we choose and is supported by the motherboard, the better, while for latency (CL), we want the smallest size in relation to speed (MT/s).
The G.Skill Trident Z RGB provides a speed of 4400MT/s, with CL19 and 16 GB per memory module.
