I will add a thought:

Make and model motherboard?

Some motherboards require that the first physically installed RAM be placed in a specific slot.

Commonly DIMMA2.

Check the motherboard's User Guide/Manual.

Msi b550m pro it only has 2 ram slots
 
This motherboard?

Verify that I found the applicable User Guide/Manual.

As I understand the documentation there are four RAM slots and the first physically installed RAM should be placed in DIMMA2

From Page 28:

∙ Always insert memory modules in the DIMMA2 slot first. DIMMA1 DIMMA2 DIMMB1 DIMMB2 ∙ Due to chipset resource usage, the available capacity of memory will be a little less than the amount of installed. ∙ Based on CPU specification, the Memory DIMM voltage below 1.35V is suggested to protect the CPU. ∙ To ensure system stability for Dual channel mode, memory modules must be of the same type, number and density. ∙ Some memory modules may operate at a lower frequency than the marked value when overclocking due to the memory frequency operates dependent on its Serial Presence Detect (SPD). Go to BIOS and find the DRAM Frequency to set the memory frequency if you want to operate the memory at the marked or at a higher frequency. ∙ It is recommended to use a more efficient memory cooling system for full DIMMs installation or overclocking. ∙ The stability and compatibility of installed memory module depend on installed CPU and devices when overclocking. ∙ Please refer www.msi.com for more information on compatible memory.

Yes. Especially if you only changed the frequency and none of the other settings. It will default to slower speeds. Then change it to whatever automatic profiles your MB offers and don't change anything else. Redo the test after.
It seems like one stick is wrong so i will take it back to the store and replace it
