I have a custom PC i built about 5 years ago. i7 4790k (DDR3, 1333/1600), with 8GB of RAM (DDR3, 1600mHz). I am looking to upgrade my RAM, and in doing so need to upgrade to a motherboard so that it is compatible with the RAM. However, does my CPUs memory (DDR3, 1333/1600) in any way hinder the performance of my newer RAM (2 x 8GB, 3000Mhz)
