Overclocking Questions

[Rowan88]

Hi, I have a few questions before I order my PC about overclocking.


1) If I am not going to overclock my CPU will the stock CPU Cooler do?

2) If my motherboard says :

DDR3 - 1066
DDR3 - 1333
DDR3 - 1600
DDR3 - 1866(OC)
DDR3 - 2000(OC)
DDR3 - 2133(OC)
DDR3 - 2200(OC)
DDR3 - 2400(OC)
DDR3 - 2600(OC)
DDR3 - 2800(OC)
DDR3 - 3000(OC)


Does that mean if I were to buy memory 1866+ then I have to overclock my CPU for it to work?

3) Its okay to have my graphics card overclocked but don't need to overclock my CPU?


Thanks and sorry if these are basic newbie questions.
