MB is recognizing my 2500+ as a 1900+

Ok, I just purchased a new athlon 2500+ barton core processor as an upgrade to my old 1700+.  The computer boots fine but will not recongize the processor as a 2500+.  At the default settings of the MB it reads the ghz at 1.47 (what my 1700+ was).  When I go to the bios and up the cpu host frequency to get the PC to recognize the 2500+ as what it is the computer will not boot.  The problem is when i up the cpu frequency the agp/pci frequency automatically goes up too, to like 78/41 (I know the 41 is right).  I tried upgrading to the latest bios and when i did my processor was then seen as a 1900+?  but still 1.47ghz, and still the same problem when uping the frequency.  My motherboard is suppose to be compatible with the barton core processors and supports the 333fsb.  But what else could be the problem besides the mb.
This is the link to my MB specs http://www.albatron.com.tw/english/it/mb/specification.asp?pro_id=30

I have a 350w psu, radeon 9800pro 128mb, 512 ddr2700, 80g wd hd.  If you need anymore info on my pc let me know please.

You need to change your FSB in the BIOS from 133 to 166.  The 2500+ Barton is an 11x multiplier with 166 FSB (1.83GHz), the 1700+ is an 11x multiplier with 133 FSB (1.47GHz).  Your AGP/PCI will remain the same (66/33).

Thats just the problem, when i up the fsb to 166 it automatically changes my agp/pci above 66/33.  And it greys out so you cant change it manually, and my board doesnt have an option to change the multipliers.

Try resetting the CMOS with the cpu installed, and see if it is automatically detected properly.  If not, you may need a BIOS update to make it aware of new processors.

I have reset the bios several times and updated the bios to a version specified for a 3000+ that would run at 333fsb.  I only saw one change when updating the bios.  With the old bios the mb didnt even recognize the processor as and athlon xp.  it simply said "Amd Athlon(tm) 1.47ghz"  When i updated the bios to the new version it then recognized the processor as a 1900+ but still at 1.47ghz.  And the only way i can get the ghz to change is by upping the fsb to 166 (which causes the agp/pci to go way up like i said before.  Anymore ideas? Is it a lack of bios options that is causing my problem.  Here is a like that shows the bios options that i have to work with. http://www.pcstats.com/articleview.cfm?articleid=1361&page=3

Yes, your BIOS options are the key to all of this.  The link you posted has a FSB of 166 and AGP/PCI of 66/33, so how did they manage to do that?  That's what you want.

Exactly my point.  It makes no sense to me why they would be able to keep it at 66/33 and i cant.  I may just invest in a new mb and see what happens.  Maybe my board is just messed up somehow, or the one they are using is a different model or something??????

Can you contact Albatron or the store you bought it from?  I understand that Albatron has a 3-yr warranty on their motherboards (I heard that from AlbertaBeef).

It's not acting normally, and you know from the site that it should be able to.  Resetting the BIOS hasn't worked, so there's not much you can do, except to exchange it.
