Question I installed a ram but my pc won't start and display is stuck on "out of range" ?

[Naozumii]

so I originally have MSI a320m mob with DDR4 4GB RAM (2666mhz) and decided to switch to DDR4 8GB RAM (2666mhz) and I only have 1 stick. When I replaced 4gb ram to 8gb my pc won't turn on and it's stuck on "out of range" on the screen. I already tried several things like clean the slots and also the ram and properly placed them, but still not working.

So I decided to just bring the old ram back but then it has the same issue, the pc won't turn on. Any suggestions or tests I can do?

sound like something came loose when you install the new ram. recheck all cables

Clear CMOS and determine if the original 4 GB RAM will work again.
