Question RAM not working in Dual Channel mode ?

[Noobartist]

Hey pros,
I will keep it short, I tried to find a solution to an issue i am having but couldnt, so you guys are my last resort.
I have an MSI z270 pro, on which i was using 4 rams - (8gb Corsair DDR4 ,3000 mhz) without any problems in the past, but i had to move and changed my cabinet and since then my mobo isnt recognizing more than 2 rams,
The Ram slots are DIMMA1 DIMMA2 DIMMB1 DIMMB2
i tried 1-3 2-4 slots, All 4 slots, switching all possible combinations, but it wont recognize,

currently i am stuck with using DIMMA1 and DIMMA2 and DIMMB1 DIMMB2 dont work if i use any rams in DIMMA1.

All 4 rams are working fine ,
Did my mobo switch to single channel ? is there a way to make it use dual channel?
anything i need to do in bios?
what do i do to use all 4 slots ? HELP!!!

You might have damaged something during cabinet change or CMOS/BIOS got reset so you need to check in there. If you have taken CPU out, check socket for damaged contacts. memory controller is in the CPU.

Yes, thanks for the suggestion mike, i will check that.
I was thinking that maybe there is a bent socket pin issue, I have never messed around with those, how sensitive are those incase i need to adjust it?

That's one problem with that kind of socket, pins are very thin and fragile. There are multiple Youtube and other instructions how to deal with it.

For anyone who had a similar issue - There was a problem with one of my pins on the cpu, it was bent, everything working fine since i fixed it.
