So the RAM sticks are each 32 bits wide, then? |

The power supply is brand new, from a reputable manufacturer. Surely if |
| 37 |
the power supply were dicky, I'd get RAM errors in some other bit |
| 38 |
position inside a 32-bit word. Or maybe the RAM into which memtest86 is |
| 39 |
loaded is also faulty. ;-( |

Sorry, I wasn't clear about that. I have just two RAM sticks for a total |
| 48 |
of 4Gb, but there are two pairs of slots on the motherboard. The manual |
| 49 |
says "put the sticks for preference in the orange slots for 'better |
| 50 |
overclocking capability'". But they (almost) work just as well (badly) |
| 51 |
in the black slots. |
