Hmm I have the KT3 Ultra.. MS-6380E.. on the box it says KT333 chipset based, however there isnt support for barton yet. I chose to get the ultra because of its RAID features, and the fact that I would pay more to get more longevity out of it..
the ultra-2 has less features, costs less but now has Barton support ?? wtf.
MY mobo in the bios has a changeable FSB rate increment of 1....... I will not be happy if i cant run a barton
