Yo estoy así ahora. Lo siento por el inglés, luego me traduzco
I want to share my config voltages with you. I'm using latest civz v3.2, and I've tested every frequency on antutu, everything completely stable with no reboots or crashes.
I'm not so lucky and I'm pvs1

but with this config I'm on pvs3/5 stock voltages (depending on the frequency) so it's fine.
Pd: on an older civz I think I was stable at 2.26ghz on 1 V, but I'm not anymore, I have to go up to 1.025 :s
