What is a safe voltage level to run my TB1800+ at?

[eno]

Epox 8RDA+ (nforce) (210fsb)
Corsair XMS PC3200 cas2.5(running at c2 and faster timings)
Leadtek Ti4400 (310/640)
Athlon XP TB 1800+(9.5x210)(1995mhz)(38c full load @ 25c case temps)
Sk-800 & Smart Case II
Antec Case

Now I got a new 1800+ TB to replace my old 1600+. I had my locked 1600+ @ 1837mhz at 175fsb @ 40c full load. I ran my voltage at 2v. I was wondering what levels to run my new TB1800+ at?

Will 1.9v last me a year or so you think for more like a couple months. It runs at 34-35c idle and 38c at full load. I want to know how much damage is running my 1800+ at 1.9v. I do not plan on needing it for over a year.

And are those speeds good compared to others?

There have been reports of chips frying at less than 1.9v if its a Tbred B, if its an A they are based on the palomino core and can take a bit more punishment due to .15 vs .13 process.

If you bump the voltage up past the recommended amount its going to shorten the life, 1.9+ it has a good chance of straight up frying, even if your temps are good
