Yeah, I've heard of people still getting them from NewEgg, but it's probably really rare. Most of them are locked after week 35 of 2003, so they've been locked for a good while. My brother ordered a Barton the other day and his came locked, but we've been able to get it to 1.980 GHz with shitty PC2700 RAM. If you had PC3200 with it, then you'd be able to raise it to 200 MHz FSB, pushing it to 2.2 GHz. The locked multiplier really only means that people with shitty RAM won't be able to go as far (or people with incredibly good cooling won't be able to take it past 3.0 GHz
), but for light overclockers, there's really not a problem.
We were also able to get the aformentioned shitty RAM to 6-2-2-2 which is pretty damn good if you ask me. I love that motherboard and CPU combo.
