(I put this on AMD's forum but got no reply.)

How damaging/degrading would it be to go above AMD's max recommended voltage of 1.30V to 1.35V with my new air cooled 4200+ X2 s939 ?

Is it real destructive to go higher?

The highest I'm able to go and still obey AMD's recommended max voltage is 1.35v X 104% = 1.4040 volts as calculated, but actually dithers between 1.344 & 1.360 volts as reported by cpu-z. So that's right at the max recommended voltage red line.

At that level I can only OC to htt 239 X 11 = core clock of 2629 MHz, temp 54 deg C while OCCT! stress test is running.

However, by increasing the voltage above 1.4 actual, I can get the cpu core clock up to 2706 or probably higher.

If it's not harmful, I'd like to at least run it at 1.250 X 113% = 1.4125 as calculated, or 1.376 as actually reported. Or higher, say 1.3 X 110% = 1.43 calc, 1.39 actual. Or higher.

Guidance on voltage limit will be appreciated. Thank you.

(Somewhere I read that actual voltage itself wears down a cpu, quite distinct from temperature effects.)
