Before that I had 2x4gb RAM DDR4 and wanted to buy 2x8gb, then I waited about 4/5 days until I switched on my PC and played on nh ps4. Then the RAM came then I connected it suddenly everything works but the mainboard is not connected to the gpu does the cpu cooler also all fans power supply, etc. Then took out the ram and put the old ram back in again has no use what should i do

co

Have you made sure that the ram is correctly inserted and in the correct slot

Cu

Yes I have

Cu

The main thing is that it has 2 RAM connections so where should the error be, both are right inside

Ra

Are you sure the ram is right inside? When plugging in, there must be a click, so just press it again from above

co

Try other RAM if available

Cu

Age, I already got a lot of answers about it before YES, I CONNECTED IT CORRECTLY!

Wr

Is the ram compatible

Ra

How am I supposed to know?

Cu

The b450m-pro-m2-max has two ram connections

Ra

That's all well and good, but that doesn't mean that you put it in the right place.

Cu

I connected it correctly tf the mainboard turns on
