Okay, when reviewing motherboards you obviously look for what Ram kit is compatible right? Okay.. so lets say we are looking at one now. It will look something like this "DDR4 3600+(O.C.)/ 3200(O.C)/ 2800(O.C)/ 2666/ 2400/ 2133" or similar. Now, I know these value in MHZ and I know O.C stands for overclocking right? My question is, you can buy ram kits say, 3200 MHZ, is it suggesting that if I buy that kit I need to overclock it? Or is it suggesting I buy a lower MHZ kit and O.C it to 3200 MHZ? For the sake of examples let's say I am using a ASUS ROG ZENITH EXTREME sTR4 AMD X399 SATA 6Gb/s USB 3.1 Extended ATX AMD Motherboard and a Ryzen TR 1950x

It's saying that standard memory speed for that motherboard/chipset is 2666MHz. Anything more than that is considered an O.C. So yes, if you buy 3200MHz memory and want to run it at that speed it will be considered an O.C. even if you simply enable the X.M.P. which after all stands for (eXtreme Memory Profile), which is a predetermined/tested overclock for those memory modules. https://www.intel.com/content/www/us/en/gaming/extreme-memory-profile-xmp.html

If you want to run overclocked memory, you should check with the list of compatible RAM kits for the particular motherboard as those are the kits that have been tested to work at their overclocked speed. Sometimes other RAM kits will work, but sometimes they won't. The CPU's memory...

Sometimes other RAM kits will work, but sometimes they won't. The CPU's memory controller also comes in to play as to whether or not it can handle the higher speeds.
