Question Double A RAM settup

[MsEllian]

My motherboard's Β1 and B2 slots are not working but when I plug in both RAM on its A1 and A2 it reads them both. Is it safe to keep them this way?

List specs

Use A2 and B2 slots.

B1 and B2 arent working at all for some reason. What would happen if I left the RAM in the first 2 slots?

 

[boju]

B1 & B2 are the last two slots. Recommended slots for dual channel is A2 & B2 ~ 2nd and 4th slot

Sorry I made a mistake at my original post I meant to say A1 and A2 when i plug the rams in it doesnt even get to BIOS. Same with A2 B2

Yes I read the manual, what I am asking is what would happen if I leave the rams into the first 2 slots that my pc is working when I do and it doesnt when I put them the right way.

If it runs, they won't be in dual channel and most likely won't run at rated speeds. For the recommended slots not to work could be the result of bent cpu socket pins or cooler on too tight. Check both.
