First thing you need to look at is your BIOS version. You need version F11, F13 or F14 for that CPU to run.

Do you have one of those?

Have you checked that cpu multiplier is set correctly? Check the manual for the board-there should be a DIP switch that adjusts it.
You may also need to set the fsb speed manually in the bios.

If you dont have a manual for the motherboard,have look at the giga-byte website.you will be able to download one from there.

Does your motherboard support barton, if not you need another motherboard that does

thanx for help so far been to bios screen here`s what i found if it helps

system information
proc.type - unknown
proc.cpuid -06a0
prox speed i666 mhz
bios date 10-07-2002
original bios haven`t flashed it have manual
not sure how to work multi plyer i believe
the front bus should be 333 ? m/boards about 15 months old supports raid and 3200 ram agp x8 so its fairly new (super 333 socket a on box)i know nothing about bus speeds please be patient.

I'm almost certain your version is too old to support your CPU, click here but you need to look at the very first screen as you boot-up at the bottom, and look at the very last set of figures.

The first BIOS that supported this CPU was dated 15/01/2003 and is F11. There have been two further revisions since then, noted above.

click here for a tutorial that will help you see what you are looking for (second page) and how to flash a BIOS. However, if you have limited experience with this, it would be as well to get someone to help you that knows what they are doing, as BIOS flashes are not to be taken lightly.

updated bios (f14) on gigabyte website
in bios system info now reads
proc type amd athlon xp
proc speed 2200
proc clock 133 mhz
installed memeory 512
bios f14
bios date 09-03-2003
computer reads it as 2200 ok iknow 2800 was never true speed but whats the next step changing front bus speed ? most things are set to auto in bios don`t notice any great speed changes as yet still feel some thing needs changing.
thanks so far to every body also to lastchip who must have visited gigabyte web site for his info nice to know people take time and trouble.
ps i did have to change a jumper when i fist put the 1700xp proc in been so long ago forgotten which jumper tanx... steve

sorry but ive just checked sytem info on xp(run dual boot sys mill-xp)and it reads
xp2200+
1.67 ghz
so its still not true speed is this where jumper comes in ?
bear with me steve

The 2800 Barton actually runs at 2083MHz. This equates to a FSB of 333 x 6.25.

So your basic FSB speed is (I suspect) 133, so you need a multiplier of 2.5 in order to achieve a FSB of 333MHz. That's the first setting.

Then, Your CPU speed will be determined by a (now set) 333 FSB x 6.5 in order to achieve the required 2083MHz.

You need to refer now to your motherboard manual, to achieve these settings.

I too am experiencing unstable or un bootable os,having built a shuttle sn45g barebones system.Having installed a amd barton 3000+chip on a nvidia Geforce2 ultra 400 motherboard,running dual line crucial 256mb DDR 3200 memoryX2.I cannot set the correct multiplier for the chip when i set in the bios the fsb to 166Mhz ie fsb333(same as the chip)and the multiplier rate to X13 it won't boot only stable with x12 ie running at 2000 not 2167 the correct speed for the chip,any ideas ?
