Adding 16 GB RAM kit to existing 8 GB RAM kit

[Joseph DeGarmo]

I currently have a 2x4 GB G.Skill 1600 MHz RAM kit installed and will be buying a 2x8 GB Kingston HyperX Fury 1866 MHz RAM kit. Is it considered safe to install the new RAM kit alongside the old RAM kit with each in their own dual-channel memory configuration, thus bringing the total system RAM to 24 GB? If so, could I overclock the old RAM to match the clock speed of the new RAM?

yes it will work
it is hard to overclock RAM above its specs

So if I cannot overclock the old RAM to 1866 MHz, then is it worth keeping the old RAM kit? Is it basically a choice between speed or capacity? 16 GB @ 1866 MHz or 24 GB @ 1600 MHz?

What are you doing that would require more than 16GB of ram? Or 8 even?

Windows 10 and Samsung Rapid Mode along with Malwarebytes, Origin, Steam, and ASUS AI Suite 3 are pushing my idle RAM usage to as much as 47%. I would need to increase the RAM to accommodate games like GTA V, running two GPUs in SLI, and multitasking with video editing / photoshop. If 24 GB is overkill, then I'll have no problem with taking out the old RAM kit in favor of the faster speed. I'm just wondering if I could mix the RAM kits so that the old RAM can still be put to some use. Otherwise, I could just sell the old RAM kit.
