Hi all, I've got an older computer that I want to add more RAM to because I've heard it will help when editing video (4K GoPro footage). Is this true? Assuming it's a worthwhile upgrade... Motherboard: MSI P67-G43 (https://us.msi.com/Motherboard/P67AG43_B3/Overview) CPU: Intel i7 2600K 3.4GHz RAM: Currently 2X 4GB Corsair Vengeance DDR3 PC12800 1600MHz (https://www.corsair.com/us/en/Categ...l-Channel-DDR3-Memory-Kit/p/CMZ8GX3M2A1600C9B) SSD: Samsung 860EVO 500GB The board supports up to 32GB RAM. I think I'd like to get 16GB more (2X 8GB) for a total of 24GB. Does it matter what type I get? Do I need to stick to the exact same size, speed and timing? Can I mix and match specs and brands? Would any faster RAM get reduced to the speed of the slowest RAM in the bank? Also - in the specs of my mobo it says the speeds are: DDR3 1066/1333/1600*/1866*/2133*(OC). I don't recall doing any overclocking I just plugged this stuff in and it worked. What does this spec mean?
