I have 2 sticks 8GB RAM, this one if it makes any difference: Kingston HyperX Fury Red 8GB 2400 MHz DDR4 RAM,

I'm looking to add more RAM to my unraid server and for some reason in my neck of the woods 2666 Mhz DDR4 RAM is cheaper at the moment. I'm not super concerned with RAM performance, but I want to know if it's safe to mix and match. I'm OK with the new RAM running at the lower speed, I'd just rather not pay more for 2400 RAM.
On the Kingston page it says the RAM automatically overclocks to 2666. I honestly have no idea at the speed it's currently running, I just plugged it and turned the machine on. I'm super novice when it comes to motherboard settings, timings, overclocking and all that.
Does anyone have any insight they would like to share regarding this?
