Correct. |

Hmm. My system *is* overclocked (I'm one of those "enthusiast" guys). |
| 25 |
I'm running an E6600 that runs 2.4GHz stock at 3GHz with a good |
| 26 |
aftermarket cooler (temps never go above 48C at full load). The CPU is |
| 27 |
overclocked and *undervoltaged* (1.29V from its 1.35V stock). The RAM |
| 28 |
is both underclocked (to get an FSB:DRAM ratio of 1:1) and |
| 29 |
undervoltaged. The system has been confirmed stable though; 8 hours |
| 30 |
Prime95 stress test with no errors, which is much more of a stress test |
| 31 |
than any real application can pull off. It also passes memtest. |

As it happens, upgrading to kernel 2.6.27 was not the only change; I |
| 39 |
switched from xf86-video-radeonhd to the proprietary ATI Catalyst |
| 40 |
drivers. Didn't think that this has anything to do with it though. |

Can you recommend a Linux program that does a stress test like Prime95 |
| 43 |
on Windows? |
