Hi Guys. I was wondering if there would be any instability issues if i use 2x2GB modules in dual channel mode and another one in single channel. the reason for this is i have a faulty motherboard with one of the 3 lanes dead. So i can only ram slots 1,2,3,4 and not 5,6.
I was planning to install the rams in 2,3,4, since 1 is blocked by the CPU cooler.
It all depends on your motherboard. On a worst case scenario, I would say that you would fall back to single-channel mode. You could possibly still have dual-channel, but running in asynchronous-mode (where one channel has more memory than the other), although this is usually the case on some boards where you have 2 sticks of RAM but different capacities, so I'm not sure whether it would be the case in your situation. Either way, you're going to see a performance hit, so I would stick with just the 2 sticks of RAM you have currently installed and keep the dual-channel mode.
