I'm not 100% sure that it is my memory that's the problem but I got 16GB of 2400 MHz ram and have it installed in my brand new machine and it is counted as compatible with my motherboard so there's no problem with compatibility but when I went into bios it was default set at 1600 MHz, I thought nothing of it and put it up to 2400 MHz but it really seems no different. My brother has 16GB of 1600 MHz ram and his system seems to be running smoother, like I don't have Photoshop but I know that takes a long time to boot and his boots up instantly whereas it takes a while even for my steam to open. So I D/L a few programs that check CPU and memory etc. and it said it was running at 1200MHz seeing as that was exactly half, I decided to do a test, so I put the ram down to 1600 and checked the program and it was 800. Something seems fishy. Also before you ask yes I am running 64bit and my motherboard can take up to 2800MHz RAM
