I'm sure this has been asked many times before but I couldn't find the answer on Google. I'm upgrading my PC and with the new r7 5800x performance scales to an extent with ram speeds so I picked up a 2x8 3600mhz kit for the dual channel benefits. If I put the same ram model just 3000mhz in the other two slots, will I be missing out on performance? I'll probably fill them anyways since the performance loss wcs would be negledgable but still curious.
