[basserho]

i have an athlon xp 1500 processor, showing running at 1.33ghz, however last week i noticed that it showed it was running at 995 mgz. how is this possible and how do i restore it to 1.33......any help is gratefully recieved.

Welcome to PC-Pals basserho! We hope you'll be able to solve your computer problem here and have some fun along the way too

Not my area of expertise I'm afraid, but our main man Bat69 will be along shortly to help you I'm sure

I'm no expert, but suspect an overheating problem of some kind which may have caused your system to slow down the clock speed of the CPU, in order to run it a little bit cooler.  But like Adept says, bat69 is our expert in this particular area.

Hi Basserho

From what you say it appears that the speed is this as soon as you switch your machine on. Assuming this happens when the machine hasn't been on for a little while ie cold, it suggests it isn't an overheating problem.

Right, it looks like your FSB (Front Side Bus) speed has been changed to 100Hz, rather than the 133Hz it should be running at.

The AMD XP1500 chip is as you say a 1.33GHz, this is derrived from a FSB of 133 and an internal multiplier of 10x. Therefore simple mathematics 133x10 gives the chip speed.

Had you had a system crash or something recently? this could have caused the problem. Or have you put in some new memory (the memory being 200Hz DDR)?

Now to restore the problem you will have to go into the BIOS, you get this as it is just booting up, you will have to press the 'Del' key (or whatever your system requires) and you will enter the BIOS.

There should be a setting for CPU speed or FSB speed, this should be set to 133Hz. It will probably be in the page named 'Advanced' in the BIOS.
I'm not sure where exactly it will be in your BIOS, as I don't know what BIOS you have.

I hope this helps, and will get you XP motoring along again at full speed


Nice to see another local northern lad too

Bats is right. Your chip is 1.333Ghz by defaul which is 10X multiplier by 133. Your bus is probalby set to 100. Just change it in your bios back to normal.

thanks for that advice, it worked and im up to full speed again again cheers O0

Brilliant, pleased to have sorted it for you.

I hope you stick around the forum, and have a little fun here. I need more northern support
