non-linux specific -> why does my AMD athlon 2000+ only run at 1.2ghz?

i have heard of overclocking, but never UNDERclocking!

Where are you seeing the 1.2 gig reference? If it is during the boot, I think you'll find that your clock speed is not set properly - check the bios settings and you'll probably find that it's set at 100 instead of 133 (or 200 instead of 266, depending on the bios manufacturer).

Yes, I don't exactly remember, but my ABS AMD 3200 was also running at a slower speed when I got it. Support had me changed something in the Bios as well.

Are you sure Athlon 2000+ isn't just the name? A lot of the time AMD names their chips with a higher speed than they actually run at. My Duron 1400+ runs at only 1ghz. Their reasoning behind it is that clock speed doesn't really matter that much (look at centrino vs p4) and that the number in the names is equilivant Intel processor

So, go into your bios (generally you hit the DEL key during boot) and look under Advanced tab. You should find the settings there. Best thing is to get out the book that came with the mobo or check at the manufacturers site for the correct settings.

Darin, yes that's true - but the Duron chips have been set at accurate values, unlike the Athalons. If yours isn't reading 1400mhz while booting, you might want to check your bios settings too.

The XP2000+ runs at 1667MHz IIRC. On my EPOX 8KHA+ mobo I had to move a jumper to select 133Mhz instead of the default 100MHz. On other mobos, this may be a BIOS setting.

jollyjoice · 07-27-2004, 01:27 PM

yes, now running at 1.6
only prob is that windows don't like it. curupted WHOLE filesystem!!!!!! linux is fine, no complaints!
where's my xp disk...

AMD numbers no longer represent clockspeed as it is an inaccurate judgement of how fast a chip is. Intel still uses it (though I heard they might dump it too) and therefor AMD's model numbers closely resemble the equivalent Intel chip's clockspeed.

Measurement of real speed must include how many cycles an instruction takes to complete, clockspeed ignores this.
