i have a athlon xp 2000 on a asus a7v8x. The vcore is set to auto on the mainboard, and is currently at 1.85v. is it too high??? should i set it to manual and input 1.75 v (original specification for my Palomino)??? or should i leave it this way?? my only concern is that the processor might be running just a little bit too hot...
