Hello, I'm currently using 2x4 Corsair Vengeance DDR3 ram sticks. I want to upgrade it to 16 GB with the same model 1x8 GB stick. So I have to do a triple channel. Problem is 2 (DIMM_A1, DIMM_A2) of the 8 slots of mine is blocked because of the CPU cooler. Can I still do a triple channel without these slots?
