I have recently lowered the Vcore on my athlon xp 2000 "palomino", it was originally 1.75v i have lowered it to 1.60v, i did this to lower temperature slightly, and it has about 5oC, it seems to be running ok and stable, is there any risk of performance loss or anything by doing this, will it affect anything???
If it's stable, it's good. There's a certain range where the voltage is okay, but outside of that is dangerous.
