I recently bought 2x8gb Corsair vengeance lpx ram sticks to replace my 1x8gb ballistix ram stick, when I’m I installed them my pc would fail to boot, no display on monitor. I took them out and put my old stick back in but it is just doing the same, i tried to one at a time but no luck and I pushed them down firmly aswell, I did noticed one of the M2a socket pins missing so I have a feeling this is why but it was already missing when I put the new sticks in
