| 408224 | 2005-11-28 00:46:00 | Hi We have a Compaq laptop which as a mobile Athlon 1800xp cpu but it runs at 852Mhz? Any ideas? |

| 408226 | 2005-11-28 00:52:00 | Underclocked, perhaps? :lol: How do you know that the CPU speed is lower that it should be? Through Everest? Cheers :) |

| 408227 | 2005-11-28 01:38:00 | So it should speed up when something is going? | music_man (5482) | ||
| 408228 | 2005-11-28 01:43:00 | Look for the cpu throttling (cpu.rightmark.org) Are you plugged into the mains or running on battery? The mobile Athlon 1800xp cpu actually runs at 1.53 GHz. |

| 408229 | 2005-11-28 09:00:00 | An issue I have had now with three different AthlonXP CPUs (although these were desktop versions) was sonething similar to this where the clock speed was halved. The problem seemed to be caused by setting the bus speed too FAST. Not sure why this throttled the CPU, all I could figure out was that when I dropped the bus speed the CPU clock went back up. None of the CPUs were overclocked at any point. This may also be a pre-failure warning - all three CPUs suffering from this problem had intermittent errors which grew steadily over a couple of months, then they finally died. CPU replacement sorted the problem. Hope this helps, I know it's a bit irrelevant and I don't know if it exactly applies to your situation. |
