Also as I stated in my original post the MB does report "AMD Processor model unknown" at post. I assume a BIOS update will be forth coming. Actually when the Phonom-I was installed it was an upgrade (well it turned out to be a downgrade) from an AMD X2 6400+. The BIOS at that time reported the same thing until there was a BIOS update for it. Also FWIW, at that time I was able to boot a HZ=1000 kernel. Don't remember looking at the lpj values though.
