It might be a dodgy RAM slot instead. If it is, you'll need to RMA your motherboard.

Try the working RAM (16GB 3000MHz) with one 8GB stick in A2. If you still get problems, try it with the stick in B2. If you still get problems, it's almost certainly not the RAM that's causing you issues. Also, if you can, go into Event Viewer afterwards and look at the logs: that might shed some light on what's causing your PC to crash.
