Ram problem

[aplaceinthesky]

Hello, today I took out my ram from my Asus rog strix b 550 f gaming to put them on another computer that has faulty ram to try it out. When I put them back in the motherboard, the system doesn't boot , it boots only if I put only one ram stick. So the yellow led turn on and the system doesn't boot , monitor doesn't get the signal

Anyone knows why?

Any tips, is the motherboard faulty?

By the way I did not touch the cpu , bacause I read that sometimes the cpu pins could get broken

Hello @aplaceinthesky 

Thank you for reaching out to us.
Could you please confirm if the memory modules are installed in the recommended DIMM_B2 and A2 slots as outlined in the ROG STRIX B550-F GAMING (WI-FI) user manual?

When using a single module, are you able to boot the system from either of these slots, or does the issue appear to be specific to a particular module or slot?
We recommend ensuring that the memory is correctly installed and clearing CMOS before testing again to see if the issue persists.

Thank you.
