Processer lost speed....

[VS]

Now,I know a fair amount about computers. Enough to maintain a healthy PC. But something strange happened the other day. I turned my PC on and at the startup I noticed the processer clock had clocked my processer at a different speed than it ever had before. It(AMD Athlon XP 2,000+) used to run at a solid 1,667 Mhz,and NEVER changed. Now,it runs at 1,250 Mhz and has not changed. What would cause it to drop over 400 Mhz?! I'm a little ticked to say the least. Only one thing,I have not noticed any change in gameplay in any of my games. I did nothing different than I usually do to cause something like this to happen. Any thoughts? -Luke

bios, check it out. I have the same problem, but I did it on purpose cause the damn thing kept over-****ing heating, only mine's a 1900+ going from 1600-1200.

Put it back on 1667.

I had a similar problem when I replaced my motherboard.

It turned out that the reason my 1.13 Ghz was running at 850 Mhz was because the clock speed of my FSB was incorrect in the bios.

Changed it from 100 Mhz to 133 Mhz, saved and exited bios, rebooted, and that solved the problem.

yup, its the BIOS*







*or at least all signs point to it

this or heat.

Blisshead might be on to something with the heat. Yes, it's a bios setting, but why did this happen?

If it's overheating, it may be trying to underclock itself to fix the problem? With mine when i have that problem, it just boots up into the bios, and selects my 1600mhz setting, and says it's incompatible, so I manually set it to 1200 and it runs stable.

There could be something more serious wrong such as heat. Damn AMD and their ****ign heat problems. You can get a really big fan and sink to fix it, but it'll be loud as hell.

Check the temperature (BIOS) and the fan.

I have my pc where I mix, so I made it MUCH quieter by changing fans.

Thanks for your help everyone. I changed my FSB in the BIOS to fix it. Thanks again. -Luke
