I have this two components that support ECC memory:

  • AMD RYZEN 3 1200
  • AMD RYZEN MSI B450M PRO-M2

On the other hand I have this memory

  • 4 GB DDR4 2400 KINGSTON VALUE CL17

Questions

  • Are they going to work together well?
  • How ECC memory affects to performance? Is this going to work slower in this case?
  • Will the opposite case work? A motherboard and CPU that do not support ECC memory with an ECC memory?

Yes, it does work together.

Yes, this motherboard will run both ECC and non ECC ram (always in non ECC mode though) according to AnandTech.

Will the opposite case work?

Depends. ECC unbuffered memory should work on non ECC memory, from LinusTechTips.
