RAM - WHICH IS THE CORRECT FREQUENCY

Question

Hello. I will buy ram for my laptop but I want it to have the same values. When I look at the properties from the CPU-Z program, I see that it is CL15 2400mhz(1200mhz), but when I look at the task manager, I see 2133mhz. What kind of ram should I get? A confusing situation is the discrepancy I see. Also, I see that Memory > uncore frequency is around 3290mhz. Can someone explain what's going on?

The maximum speed for RAM on that CPU is 2133 MHz. While you can install faster RAM, it will downclock to 2133.

You still haven't posted the system model number, but if you're looking for RAM guaranteed compatible, visit www.crucial.com and look up the specs by system model number.

The existing RAM is DDR4-2400; the CPU controls the memory speed. If this is the OEM RAM for the system, it's likely whatever CPU you have has a 2133 MHz memory controller.

It would help greatly to know the exact system model and CPU model you have. Alternatively, many memory manufacturers have configuration tools you can use to select the correct RAM for the system.
