ram voltage, how much is too much?

i've read that using high voltages can fry or greatly shorten the life of ram. I also know that higher than stock voltages are needed for high overclocks. I want to overclock my crucial 2100 256mb ram, but what voltages are safe, what are dangerous, what's the tradeoff? I don't want to kill any ram. Any help would be appreciated, thanks.

I've heard that up to 2.8 V is okay.

anything up to 2.95v is ok as long as you have good ventalation for youre case. anything over that and you might need some kind of cooling for the ram.(fan or heat spreader). it also depends on the ram. but most good ram sticks, crutial,corsiar,samsung can handle the high voltage with no problems.

goodluck!

I've had my Crucial up to 2.9v. Right now it is at 2.7v and running 166 MHz FSB at Fast settings. It won't go over 174, and mine isn't stable over 168 for more than 2 hours.
