It is the same deal as was with the Kt133a chipset many moons ago. They where not supposed to be able to run a Athlon Xp proc newer then the Pally 2100+. I be damn if I don't have a 2400+ Thoroughbred running in my Kt7a without issues. And the bios picked it up and Id'd it for what it is. I am not saying go out and buy a fx chip for your Am3 board as this does need to be investigated and tested first. You could plug the chip in and boot it and it will run it fine or it could go up in a ball of flames. I have no clue but I do know someone who may try it for us. Oh Norton, buddy pal of mine. Why don't ya fire one of those fx chips up in that EVO board.
