I recently upgraded my MSI K7T Turbo to an XP1700+ and while I didn't flash the BIOS, I did set the jumper for 133 Mhz front side bus. It recognizes my XP1700+ as a 1.466 ghz Athlon (correct speed, even if there is no such thing

). And it works fine, Sandra also recognizes it as a Athlon 1.46 gig. I have downloaded the updated BIOS, but haven't had the guts to install it yet. (My history of flashing BIOS's is 1 for 1, but I was more than a little nervous about trying it

) Does your K7T support the 133 fsb? If not, then it will probably see it as an Athlon 1.25 gig.
