You need to up your voltage once you're no longer stable at stock voltages. Test using Prime95 blended (or other stress test).

My Chip started at 3.1 GHZ IM trying to reach 3.7 GHZ but its not stable. (After 2 hours of folding she crashes)

How ever at 3.6 i folded for 2 days.
If you are crashing while foldng you pretty much need to do it now

i can not remember the exact figures, but i read here somewhere running a 955 at 1.55v would decrease its life expectancy (assuming cooled below 55c under load) to 5-10years?

so at any rate it would be obsolete before it dies from high voltage

But how long until there a drop in performance?

(Since there is a decay before death)

Ohh and i dont want to be a A$$ but you have the source of this info?
[EDIT]
I was reading up and i guess that can be true.
I raised it to 1.375 and thats all it needed. Stable at 3.7
I can probably go 3.8 but ill try that another day.

sorry it was on these forums from someone but im not sure who. 1.375 @ 3.7ghz is nice, you should blend for 3 hours to be sure!

Here ya go. The article says, CPU health will decline slowly and steadily.

One thing that I think it is absolutely critical to discuss is voltage
and temperature. Many people will easily exceed Intel recommended voltage
for their processor by 20% or more. However, they won't for a second run
their processor over Intel's maximum recommended temperature.
This is rather silly. Over voltage plays a far more significant role in
how long your processor will last than temperature does. However, both
are important. Your computer will die just as fast at 10C as it will at
80C if it has 25-30% or more over-voltage.

How much voltage you put into your processor is up to you. It is really
un-known how long processors will last at certain voltages, so a safety
range is not easily determined. However, be aware, your processor will
likely not die instantly from over voltage. It will be a steady and slight
decline of performance. You will need more and more voltage just to keep
your system running.

The term is electromigration. The actual electrical pathways thin out
over time as electrons move throughout the chip. The more voltage/current,
the more/faster electrons are traveling and thus the faster the pathways
thin. Once they get thin enough, EMI plays a larger role in the stability
of the chip and eventually the pathway will break, killing the chip permanently.
This process normally takes 1 to 2 decades, but when you over volt, you can
drastically accelerate the process.

This is why overclocks which use a lot of voltage can become unstable after a couple years.
