My configuration is Core i5 3570k CPU, Asrock Z77 Extreme 4 MB, 8GB DDR3 Corsair Vengeance RAM with 1+2 TB WD HDD.
I'm currently using my 2 RAM slots with 2 4GB DDR3 1600 Bus, 9-9-9-24 RAMs. Can I use another 8GB DDR3 RAM of same generic on my 3rd slot? Also if I put another 8GBx2 RAMs in other 2 slots, will I be using the total combined RAM of 24 GB?
Please help me my advising!
