I don't get exactly what your problem is, but have you tried to plug in the RAM stick and see what happen?
You said that you got 8GB Adata DDR3 1600.
Have you checked your MOBO compatibility with 1600MHz RAM?
Is it a single 8GB stick or 2x 4GBsticks?
what is your current RAM specs?
You can't mix your old RAM and new RAM together. Let's say you have 2GB DDR3 1333MHz stick plugged in and you want to add single Adata 8GB 1600MHz stick, you can't
And for the record, people are having many problems with Adata RAMs. My friend bought Adata 2x 4GB RAM sticks and he went thru many troubles just to get it to work
