I have the ASRock FM2A88X PRO3+ ATX FM2+ Motherboard and the A1 RAM slot is blocked by the CPU cooler heatsink (we tried putting RAM in it; the RAM lent slightly to the side and when we turned the PC on it just beeped), so I was wondering if I could get dual channel performance by having 2 RAM sticks in any combination of A2, B1 and/or B2. Thanks!
