No help. :-( No matter how I plug in the RAM (4 combinations of 2 sticks into 2 pairs of slots) it is always b11 which fails and always at an address ending in (hex) 0 or 8. How is this DDR3 Ram organised? Is each stick 64 bits wide, or are they 32 bits wide, being accessed by the motherboard pairwisely? If the latter, I would have exected the failure to move to address ....4 and ....C when I swap the two sticks. Am I being prematurely pessimistic in thinking the motherboard might be the fault? > > alan dot mckinnon at gmail dot com > -- > Alan Mackenzie (Nuremberg, Germany).
