Athlon XP and MBO troubles

I purchased a Chaintech socket A model 7AJA2E and an Athlon XP 1.4 GHz.
The specs on the MBO claims it can support up to 1.4 GHz with a front side bus of 200.
The processer is incorrectly identified as a 1.05 and I have a FSB of 100.
The manual claims there is a jumper setting, JP9, that is set to 1-2 by default for 100 FSB. 2-3 is for 133 FSB. Problem is, 1-2 is soldered by default.

I did try to unsolder it and resolder to 2-3, it did identify the CPU on start up as correct but then it froze and would do no more.
So I set it back to the way it was.

There is no option in the bios, as far as I can tell, to change the FSB.

The board can be identified here http://www.evertek.com/include/offsite.asp?Action=Frames&Url=http%3A%2F%2Fwww%2Echaintechusa%2Ecom%2Fproducts%2Fsocketa%2F7aja2e%2Ehtm&ReturnLoc=http%3A%2F%2Fwww%2Eevertek%2Ecom&

If anyone has any ideas or suggestions it would be greatly appreciated.

I believe that your BIOS is telling you that the CPU in question is really a 266 fsb 1400, as opposed to a 200 fsb part.  The 266 fsb 1400 would achieve its rated speed with a 10.5x multiplier, hence the 1050 MHZ speed on a 200 fsb.

By any chance, are you running the RAM at the hostclock + pci setting?  If so, this could be your problem.  If that were the case, you were attempting to run your RAM at 166 MHZ, a speed not easily attainable with PC133 SDRAM!

At this point, since you are unlikely to RMA the board after your "fsb mod", make sure the RAM is running at "hostclock", then unsolder the jumper once more, and try running the proc 266 fsb.

The KTE133 chipset is not guaranteed to run at 266 fsb, BTW.

Cheers Fubar that was alot of useful information.
I am going to go get a better MBO instead to support my chip and use this one for a slightly older Athlon I have.
I needed 2 anyway
