right, slight breakthrough. it POSTs with one stick of RAM in the third slot along from the CPU.
thoughts?
basically, slots 1 and 3 are working fine with both sticks installed, but any attempt at trying the dual channels won't work as the two closest to the CPU aren't working.
That can be one of 2 things.
Firstly, the slots could be faulty and that means a possible RMA. Check that your cooler is not to tight, as it can warp the board enough to affect the ram slots.
Secondly, if you have a couple of bent pins in the Cpu, they may be affecting the dual channel. So have a closer look, preferably with some sort of magnification lens.
So, it works with a stick of ram in slots 1 and 3 but not 2 and 4?
Is that the same with the other stick?
