That depends more on the CPU than the mobo. Just increase it until it fails to boot if you want to find the absolute max.

It depends on your cooling. Voltage won't kill your chip in the short run, temperature will. Never go above 50°C as that is the usually the threshold of stability.

From 1.85v on a 130nm chip like the barton will start shortening its life. However such a chip doesn't have to life eternally

There's only one way to find out

I ran a 2500+ Barton for about a year at 1.85V and subsequently a 2400+ mobile at 1.9V for about the same time. They were watercooled at the time, now they are still alive and kicking at around 1.7V on air, embarrasingly enough, at just 10% less mhz. Gizmo was running a mobile around 2V with a direct die block for forever I think.

Well running it like that will shorten the life of the CPU. So instead of running for like 20 years it will run for like 10 years. Which is a time longer than the desired lifetime of such a CPU.

I've been running 3 mobile XP-M's, all of them are now still running above 1.85v and for quite a while 24/7. However the warmer the CPU while doing this the faster it will get weared out. And running the CPU at a frequency above your "sweet spot frequency" will also lower its lifetime. You know, the point where raising frequencies drastically needs more vcore. And finally, a lot will probably depend on the specific chip one uses.
