I got my 2400 mobile barton yesterday. I can hit 2.53 GHZ but it requires 2.0 vcore, currently priming for about an hour with no problems. Even at this high voltage my temps are pretty low since I am using an SLK900A with a 80mm tornado fan, it doesnt even break 46C at full load. I am also able to run 2.0GHZ at 1.45V, 2.2GHZ at 1.6V and 2.4GHZ at 1.8V, all stable. I am using an NFS-7 v2.0 and 2x256mb Kreton PC3500 at 2.0-3-3-7.
