Just wanted to add my new chip to the thread as I didn't see the marking listed. I got the chip this week and is marked L804B159 and packed on 3/19/08. The chip has a VID of 1.275V which is great .

As far as overclocking, I think I am severely limited by my old board, a P5W DH where I can't get much stability at all with high FSB settings .
