X-post from MSI forum because they were unable to help me. I nees dome help. i've tried fighting this issue for over 3 weeks now.

So i've tested both sticks in different combinations of slots.
End results:
1.B1+B2 or B1+A2 or A2+A1 (single channel variations) are working fine. BIOS warns me that i'm using sticks in non-optimized slots (and shows me in pictures that i have to insert them in A2+B2 slots), but it sees both sticks and says that i have 16Gb of RAM in total.
2. A2+B2 or A1+B1 (dual channel variations) are not working properly. Upon booting PC gives me 3 long beeps (bad ram) signal, and proceeds booting. In BIOS it sees both sticks in both slots, 8Gb each, but then says that i have 8Gb in total.

I've tried testing sticks, both are working normally on their own. Don't even know where to look to find a clue of what's wrong.

Thanks in advance.
