xp2600 problems

  lukecarey 22:44 19 Sep 2003

i have just bought an athlon xp2600. It is running too low and in boot up and windows XP is "unkown CPU type." i have gathered i need to change the fsb to 166 as the chip has 333mhz fsb, i have changed it to this on my jumpers but the bios doesnt have a 166 option i have also been told i could change the multiplier but i dont have the option to in my bios. i have downloaded the latest version for my board but no change, any help would be appretaited.

Try this click here, lukecarey, it should identify the processor you have.

it says the core speed is 1.24hgz but my processor should be running at about 2.3ghz but theres no options in my bios which allow me to get it that high, is there somewhere i can download a bios which will have the options?

If your BIOS dont support a 166MHz FSB then you have bought the wrong CPU as your mobo only supports a 133MHz FSB. If you managed to get your mobo to run on a 166MHz FSB the AGP and PCI buses would be running out of spec as your mobo wouldnt have the dividers needed so it would probably be very unstable.

The only way to change the multiplier would be to unlock the chip which isnt something i would like to have a stab at as it is very easy to kill the chip.

an XP 2600+ on a 166MHz FSB runs at 2GHz not 2.3GHz BTW

mine runs at 1.66ghz on 166mhz fsb

Did you ensure that your motherboard was capable of using that grade of CPU before installing?

And did you use CPU-Z? What model of CPU did it say you are using? Which Motherboard are you using?

Athlon XP1600 tb, havent a clue what motherboard it is, i bought a barebone system from cubesystemz.com, says it supports up to 2400 so probably not the best idea me getting a 2600

You say you've got a 2600, lukecarey, is Athlon XP1600 tb a misprint, did you mean Athlon XP2600 tb??

The Athlon XP1600 tb runs at 1.4GHZ on an fsb of 133

Looks like your PC wont support the 2600, if that's what you have.

yeh i got a 2600, i have been reading some forums, if i unlocked the multiplier would i be able to get it up to the correct speed or would that just cause more problems?
