If you do not have a motherboard that is updated for Ryzen 3600X , then nothing will happen.
1.You will either need to get your hands on a Ryzen+(EG 2600) CPU to flash BIOS to make motherboard compatible with Ryzen 3600X
2.Have a motherboard with Flashback or similar to get your 3600X to work
3.Get a boot kit from AMD shipped to you ,might take 2 weeks and not sure if they do it anymore
4.Your 3600X may work perfect if you bought a motherboard already updated for 3600X ,then just go into BIOS hit F6 and save and exit.The motherboard will set optimized settings and will work fine on reboot and Windows 10.
