Well my friend just buy a SOYO Dragon Plus (KT266A with RAID), and it worked good, but a little slow on booting. I tryed to overclock using the BIOS, since it have all the parameters there, but it didn't accept on booting at 1333mhz with 133Mhz bus (10x133), not only it didn't overclock but you have to reset the BIOS with the jumper for making it boot again at default speed (it was an Athlon B 1200). It was extange because my A7V133 alows it, I sopouse there were diferent chips, you know closed bridges or something. My fried came to me last week saying that he was changed the board for a A7V266-E, I test the overclocking again and this time it work perfectly, but they apears to be similar boards, and also, when the ASUS didn't overclock, you reset it and boot at default speed, no need to reset the BIOS.
