If I have a working computer with a 1,75V core on amd xp1600+. Can I buy a 2100+ with 1.85V core. Why I am aksing? Cause someone is selling a xp 2100+ without being able to answer me if the cpu is palomino or thoroughbred. I want Palomino cause I dont think I can change V core through BIOS Or do I have to do so?
