I got an Asus Z170-A motherboard but I am a first time builder with probably a stupid question. I want to buy DDR4 RAM anywhere between 2600 - 3200mhz. So I will have to over clock it in the xmp profile. Since I will have to over clock, I'm thinking that the processor I get will also have to be unlocked in order to over clock the RAM. Originally I was going to get the i5-6500 which is not unlocked but if I have to over clock the CPU to be able to over clock the RAM I may have to get the 6600k. Am I correct or can you over clock RAM without over clocking the CPU?
