By the looks of it, its going to be a locked chip. The stepping you show (AQYFA) is a stepping is always locked, at least from what I've seen. Also, if you look at the week (0341), it shows Week 41, and just about all of those are locked. Refer to this thread for more info on how to tell the difference.
There is still O/Cing hope for you though. Good RAM and a good Mobo will allow you to O/C it just about as far as you can O/C an unlocked one. Good Luck with the chip!
