I have a Kingston DDR 4 2133Hz 8GB and I can’t find another stick with 2133Hz in my area, so I thought that if I overclock my current stick 2400Hz I could buy another stick that has 2400Hz NOT overclocked. I have 8GB and I want 8GB more so that I will Have enough RAM to play GTA 5. By the way I have a few questions: GTA 5 is lagging on my computer, and when I check the task manager in order to try and find what causes the problem, I see that it is NOT the RAM, but the CPU that is fully used 100%. GTA 5 uses about 2GB of my 8GB RAM. I have Intel Core i5 6500 3.2Ghz and I don’t know much about what are Hertz and how they work. Should I overclock my CPU in this case and see if that is what causes the problem before I buy another RAM stick? Will overclocking anything hurt my computer? And, GTA 5’s recommended requirements say 8GB RAM. Does it mean that the computer must have 8GB or that GTA 5 uses 8GB? God bless whoever reads this and answers, you might just end my problems!
