No help. :-( |

No matter how I plug in the RAM (4 combinations of 2 sticks into 2 pairs |
| 31 |
of slots) it is always b11 which fails and always at an address ending |
| 32 |
in (hex) 0 or 8. |
| 33 |
|
| 34 |
How is this DDR3 Ram organised? Is each stick 64 bits wide, or are they |
| 35 |
32 bits wide, being accessed by the motherboard pairwisely? If the |
| 36 |
latter, I would have exected the failure to move to address ....4 and |
| 37 |
....C when I swap the two sticks. Am I being prematurely pessimistic in |
| 38 |
thinking the motherboard might be the fault? |
