I'm a newbie so I'm not sure what the advantages/disadvantages doing this pinmod has compared to the motherboard vcore mod, but I would like to know. Maybe some of the pros can answer that one :D
Something I just thought of -- you probably have to start with a lower vcore bios setting if you do the pinmod. I'm pretty sure that jumping the pins bypasses the bios settings. I would set it back to the default 1.340v in the bios to start.
