I currently have 2 sticks of Corsair CMK16GX4M2B3600C18 memory in my ASUS ROG STRIX Z270F GAMING LGA1151 DDR4 with Intel 7th Gen Intel Core Desktop Processor i7-7700K (BX80677I77700K) . I was going to get 2 more sticks but apparently this memory is not ease to get anymore and the couple instances available are on Amazon scalping. Any suggestions of 2 additional sticks I could purchase that would be compatible with what I already have? Thinking to maintain the timings if possible.
