Video Card Voltage Increase

I recently started overclocking my Geforce 8400 GS. I got it on ebay, and the seller is still selling the same model. The link to one of the current auctions can be found here: http://cgi.ebay.com/Nvidia-GeForce-...emQQptZPCC_Video_TV_Cards?hash=item4ced76678e
It has a G98 core, and today I got it from 540MHz GPU and 500MHz memory (mose likely half of the actual memory speed) all the way to 592MHz GPU and 603MHz memory. I thought it was stable, but at the very end of Game Test 4 in 3dmark it crashed on me. I still want to get it a bit higher. I overclock it with ATItool, but I also have Rivatuner. I heard that Rivatuner can raise voltages, and I want to try to do so. What is a safe interval to raise voltages by? I don't want to destroy my card that I just got to its full potential :D. I wouldn't usually dabble in voltage increases, but since my load temp WHEN OVERCLOCKED is still currently about 47 degrees Celsius, I feel pretty safe about temperatures. I would also like to get one thing cleared up: overclocking and voltage-increasing only damage a card or lower its lifespan when it gets hotter than usual, right? Is the temperature the only deciding factor in your card's lifespan increasing or decreasing?
 
when oc'ing the voltage it is generally safe to go up by like .05 v or so at a time. i haven't done voltage increases that much so don't take my word too heavily. obviously you shouldn't increase it too many times. i only raised mine like .5 v (of course my card is ati) and got a pretty high clock speed.
 
I guess this doesnt really help you cause I am at stock voltage but just thought I would throw it out there. What make is your card? Mine is a cheap PNY but it sure does run cool. I cant get it above 60c cause my cpu bottlenecks it before it can work hard enough for those temps.
