I bought myself a new cpu cooler the hyper 212 evo! works great and is so much better than my fx 8350 stock. However after it had been installed i launched up bf4 and suddenly was experiencing fps lag that i had never had before. I dont have a clue why this is happening. The only thing different i have noticed is that my ram instead of being 16gb says 8gb available and 8gb hardware reserved but surely this would not be causing my fps lag however i dont understand why thats happening anyway? can someone help me with both the fps lag and the ram and tell me if the ram thing is the cause?
