well 1: you cant run a skull trail with 1 cpu.
2: 1.6v 24/7 would kill a cpu even if it is under water and a retailer would deffo not be sending one out volted like that. (mind you vadim went bust so maybe)
MAX safe on a 45nm cpu with good cooling is 1.45v, make sure you watch your temps. You will need to play around with the other voltages though not just the cpu matey.
