I'm a bit puzzled about finding RAM that works with my motherboard. PC part picker says the RAM is compatible, but it's rated for a higher speed. My motherboard supports up to 2666 MHz, but I can't seem to find any 2 x 8 RAM sticks with that speed; they're mostly 3000 MHz or higher. Is it okay to use these faster RAM modules?

This kind of situation happens often with older motherboards. You might need to go into the BIOS and manually adjust the RAM speed to underclock it. While it's not the popular choice, it can work just fine!
In most cases, the RAM will downclock just fine. Finding the exact supported speeds can be trickier in the specs, though. Crucial used to be great for this, but I'm not sure how viable they are now. Manufacturers don't have much incentive to keep slower speeds in production since faster ones cost about the same.
Don’t worry, it will automatically adjust to the maximum speed allowed by your motherboard, so you should be good!
You can definitely run the RAM at a lower speed, so using those faster sticks shouldn't be a problem.
I'm curious why you’d pair that motherboard with only 2666 MHz support. It’s usually best to match your RAM speed to or exceed what the motherboard supports. If I were you, I’d look for a motherboard that goes up to at least 3200 MHz. The one you're currently looking at might be outdated.
