How much voltage can a P3 safely handle?

Hey all. I've just recently been messing around with my P3 866 rig again, trying to overclock it even higher than the 1.13 GHz it had been running at for the past 3 months or so. I stuck on a new heatsink (Thermaltake 6Cu+) and messed around with the FSB and voltage for awhile. At the moment, the highest stable speed I have attained is 1170 MHz at 1.80v. When set to 1202 MHz at this voltage, it boots into Linux and runs fine for a few minutes, but then applications start to crash every so often.

The system isn't running all that hot (no way to get an accurate reading in Linux, but immediately after a power cycle the BIOS says 26 degrees C) so the issue must be voltage. What I'm wondering is, how dangerous would it be to up the voltage to, say, 1.90v? I might just have the most overclockable P3 ever made, so I don't want to blow it up by overvolting it beyond a safe level.

Thanks for any advice! :)

For me personally, I would limit it to 1.90v, if your cooling is good that should be OK.

my limit is 1.85V but lots of guys have been using higher with good cooling!
don't know how long their cpus will last though.
