    Hello and welcome to Techspot.

    Your cpu should run on an fsb of 166mhz(333mhz effective) Giving you a cpu speed of 2083mhz.

    See HERE for AMD Athlon XP specs.

    Check in your bios that the fsb is correct.

    Regards Howard :wave: :wave:

    I`m sorry, but you are wrong.

    An AMD Athlon XP2800+ Barton core, is supposed to run on an fsb of 166mhz(333mhz effective). Giving you a cpu speed of 2083mhz.

    The fact that you`re running it on the wrong fsb is why you`re getting the unknown cpu type

    Try setting your fsb to 166mhz, and you will see that your cpu is then properly identified.

    Check the link I gave you.

    Regards Howard :)

    as far as updating the bios you would have to go to the EMachines website. IF they have any they would be under the support section. but I wouldnt hold my breath Emachines was never to great at support.

    if there is not an option in the bios then there should be a jumper on the motherboard.

    I`ve just been looking at your mobo manual.

    Your mobo doesn`t support an fsb beyond 133mhz(266mhz effective)

    That`s why it wont recognise your current cpu, because your cpu requires an fsb 166mhz(333mhz effective)

    Your mobo`s fsb is set via a jumper on the mobo. It only has two positions 100mhz, and 133mhz.

    You can get your mobo manual HERE

    i see iwell i cant afford to buy a new cpu or mobo at this time i mean it doesnt recognise my cpu but everythigns running fine do u think i need to get another chip or install another mobo or can i get away with this one with the unknown cpu type everything runs fine no heat problems no program problems no crashes etc. so is my cpu in any danger that i dont know about? and thanks for all the help man really appreciate it.

    If as you say your system is running fine, then I wouldn`t worry about it.

    No your cpu isn`t in any danger. In fact because your cpu is being underclocked, it isn`t working as hard.

    Running at 2.13GHz makes me believe it is a 2600+, not a 2800+. It does indeed use a 133MHz FSB & has 256KB of L2 cache.The multiplier should be 16x, any application such as CPU-z, CPUID, Everest will help you find that out.

    it runs fine its just underclocked due to my mobo but it runs fine so i am not worried about it "if it ain't broke don't fix it" lol but it is a 2800+ bought it from newegg its just underclocked thats why it comes up as 2600+ my mobo cant support anything higher then 133 fsb and the cpu requires a 166 fsb but all is fine so i am not worried about it anymroe thanks for the posts and help guys

    I think Didou has got a very good point.

    There is a particular model of the Athlon XP2600+ that does indeed run at 2.13Ghz..

    I don`t know why I didn`t think of that doh.

    I guess I was too hung up on you saying you had an Athlon Xp 2800+

    It all makes sense now.

    Cheers Didou.

    it if is infact an athlon 2600+ i still get unknown cpu type even if it does run at 133mhz plus my jumper on my mobo is already set to 133mhz so what now maybe newegg sold me a refurbished cpu iread on newegg.com alot of people who bought the athlon xp 2800+ there cpu recognised it as an 2600+ but either way i am still gettin unknown cpu type if it is an 2600+ so what now lol?

    Well, now we`ve deffinitely established what cpu you have.

    Maybe doing a bios upgrade would indeed allow your cpu to be properly identified.

    However, since your system is running just fine, I don`t recommend that you do upgrade the bios.

    Flashing the bios always has the potential to go wrong, and leave you with a dead mobo. So unless there`s a real good reason to do so. Don`t.

    Obviously it`s upto you.

    You will need to go to your mobo manufacturers website.

    You should be able to get the latest bios from there.

    Read, and follow all the instructions carefully.

    i dont think i will flash my bios the risk is greater then the reward any my comp seems to be running fine so i dont want to take the chance and screw it all up and have to end up buyin a whole new mobo or worse a whole new comp.
