New Ram Stick Added * Problem

[Poka]

Hey guys goodmorning hope everyone is doing wonderful today , quick question i just recently added in another Ram stick with same Speed and Latency it worked wonderful with my pc  now having 16 GB unfortunately whenever i check my bios it says the first stick is only using 2400 Mhz while my new added Stick is using 2667 Mhz i've been really trying to edit and push my first stick to 2667 since thats what the Ram did say it was in the box but i cant seem to find how to change the speed being used on my first stick , if anyone can help me or give me steps on how to increase the speed on my first stick so that it matches with my newer stick that would be wonderful ! , also my Bios system is down below.

 

MSI Bios 5 ---> my current bios.

Did you check if the ram stick is correctly fitted in

Or if the Ram is compatible with mobo?
