hello from Poland

I've just got brand new computer with P67 PRO3 and also have same problem - monitor in idle and not posting MB with 45 code on DR Debug. I have 2x4gb of polish RAM producer GoodRAM which was recommended everywhere.

I pulled out one stick and MB posted correctly and I have installed Win7 correctly and without problems. So it seems it's sth with dual-channel. I have to try two sticks with crossed colours in single-channel

and still I don't know it's worth to complain because it works well with one slot and on the other hand I bought two sticks to have dual
