they probably havent updated the programs that you are using to id the chip. they have to include that chip in their database before the program will identify the chip as a revision of it...
like sandra reports the athlon xp as an athlon mp i think...
not sure because i havent had that chip, or seen one tested in sandra...
i know that the bios for the k7s5a didnt report athlon xp's as xp until they revised the bios..
so i would say, that if you check the manufacturer's website, and see that they use the kt266a chipset, then you should be safe in assuming that the board has that chipset. and if you wait a little while, they will probably release an update for sandra, cpuid, and the likes that will make them report it as a kt266a...
remember that this chip is basically the same, they just revised it so that it is a little more optimised, and a bit more stable.
at least it isnt reporting it as a via appolo mvp3....then i would be worried!
