[SOLVED] Question about ram compatibility

[Yout2]

My computer currently has 2 sticks of 4gb DDR4 G.Skill F4-2133C15D-8GVR. I was wondering if the 4gb DDR4 G.Skill F4-2400C15D-8GVR would be compatible. They both have everything the same expect the model number from what I can tell.

Short answer = yes, they're compatible.

The memory controller needs all RAM sticks to run at the same speed. While 2400MHz/3000MHz/3200MHz/3600MHz/etc sticks will be compatible with the existing 2133MHz ones, all sticks will run at the speed of the slowest stick(s) which will be 2133MHz in your case.
