i don't think htt 3.1 is supported yet. i know the 790fx can't support it and the later rd890 doesn't seem to support it. the new phenom cpus will fully use hyper transport 3.0 which is speced to be 2.6ghz although current phenom I cpus have hyper transport speeds of 1.6, 1.8 and 2 ghz. i think i remember reading something a really long time ago that when you put in a phenom II the default nb speed and hypertransport speeds is 2.6ghz since the current chipsets actually support it but the current phenom I cpus cant. so from my understanding that am3 cpus will run the same hyper transport speed no matter which board they are in (am3 or am2+). which is another reason why i can't see why they would have two different sockets when they are the exact same. im not 100% sure about this but i asked my dad about it a few months ago.
yea i have seen in everest that it says it supports ddr3-800 although there is no way of testing this. im a little confused on the topic because i don't know why they would put a ddr3 controller on the original phenom I. unless they have been planning this from the start so they could phase in a more powerful ddr3 controller later when they move onto am3.
