Hey everyone, doing a little overclocking with my Athlon listed in the sig. On an old AM2 board, so having to actually undervolt according to bios. Intel CPU shows CPU to be stable in 10 passes.

CPU Z has me at 3.36 ghz current voltage at 1.25-1.28. According to HW monitor, during stability tests, I was hitting 1.46 volts under load. Temps are staying at 30-35 under load on the cores. Am I safe on these voltages or go down a little more?

Max vcore is listed as 1.4V.

Each overclocker has their own comfort zone. I prefer to stay well under factory specs for voltage and heat if at all possible. (Particularly heat)

ok, because I don't think it's hitting it long, I'll lower the volts a little more and see what happens. I thought stock voltage on these was 1.35 and I think I'm already set at 1.25.
