The G.Skill kit for desktop features 2 DDR3 RAM memories, with a speed of 1333, and a total capacity of 4GB. The response time of the RAM memory to the commands received from the system is called CAS Latency. The smaller the CAS Latency, the better for memories with the same frequency, otherwise the frequency is more important for the speed of the memory. The memories of the kit have CAS Latency 9.
