2.8 athlon reporting as 1.25

  reburner57 13:02 31 Mar 2006

I have a 2.8 athlon running in my pc and have had it for about 18 months. The machine seemed to be a bit sluggish of late and now i've noticed that on boot and in system properties it is reporting as a 1.25 Athlon all of a sudden. It previously reported Ok as a 2.8. Anyone got any idea what might be going on

Sounds like the FSB has changed,has the pc time also been acting up?,it may be the motherboard battery is ready for renewal.

PC time hasn't been a problem. Would battery running low actual affect performance ????

Only if it changed the CPU/RAM settings back to default,it would make them run slower than they should.The pc would still work just not at full speed.Usually the FSB/Time changing for no reason is a sign the battery is losing its charge
and needs replacing.There may be other things that can cause this but the battery would be my first guess.

Thanks for the help. If it is the battery do I need to do anything once it is replaced ???

You may need to set the date and time,and also reset the correct FSB/RAM speeds,but it maybe your mobo will do that for you some do.

Looks like a 2800+ Athlon which runs at 12.5 x 166[333] 2.075Ghz.
You could try resetting fsb to 166 in the bios first if it keeps going back to 100[x 12.5] thus 1.25GHz you could then try a new battery.

Ok thanks for help. Replaced battery and reset FSB to 166 in the bios and all is well. CPU reported as 2.8 Athlon.

Only thing wrong now is that my intellimouse ceased to work when I put the new battery in. Tried it in different USB slots but no joy. It lights up during boot but no response thereafter. Any suggestions ??

Have a look in Control Panel, System, Device Manager. Check for exclamation marks and that the USB is working properly. Perhaps you accidently switched off the USB in the BIOS?

first step would be to reinstall the drivers to dule them out

Have no USB at all. I'll check Bios to make sure I never switched it off
