I have an Asus A7V revision 1.02 with a duron 650Mhz. 3 months ago i tried to buy a thunderbird with a 200Mhz bus and i didn't find any. i know i can't use a xp in my board but is a duron with a morgan core (1200Mhz or even more) compatible with my board? will a thunderbird 1400 with 266 bus work if i set the bus to 200Mhz? it will be a little slow..i would prefer a duron with a morgan core..is there any bios that suports it?i really can't afford a asus A7v266a rigth now..🙁 thanks in advance..
