Only 1 ram is usable

[talbion]

I have been using 2 rams(2x8gb) that have different speeds, one is 2400, other one is 2133 Mhz. While i put new thermal paste on my CPU, i took out rams and put it again and now i can only use the one that has 2133 mhz speed. I do not know how to fix it but i remember it happened once before and i remember somehow i fixed it in BIOS but idk how Help me ;c i'm addicted to overwatch(sorry) but i cant play it on 1 fps with my gf ;n;

Can you try to change both to same clock speed or disable XMP? I'd highly suggest you get at least a matching 2x8GB RAM stick set

Do you remember to put all the RAM at the same slot as before, or in the slots where theyll work in dual channel? If you have more than 2 slots of RAM youll need to match the channel according to the motherboard manual.
