To be clear, you validated a 4621 (220x21) at just 1.39 Vcore. What happened when you raised Vcore to higher values? What Cpu clock did you achieve? I'm asking cause I might want to hop on the Ebay guys batch, but I'm already doing 4662 with my C0 and a superpi 1M run, so I wouldn't want to "upgarde" to a 4621 chip. But that was at 1.488 vcore so your D0 may still be way ahead of me with same vcore.
