Since this was not mentioned yet: |

Maybe because the ram was not faulty at all. |

Maybe it really operated in the range of allowed tolerances - and those |
| 22 |
were never crossed with memtest as a very light system load. |

But with an OS booted, the CPU, graphics solution, harddisks all sucking |

power like mad, your mainboard or PSU might not be able to deliver as |
| 26 |
stable currents as the specifications demand. Some memory is more |
| 27 |
tolerant than other. |
