like honnestly, Ive never heard anyone killing there cpu running her @ ~1.55V..usually cuz there temps are ok.... u can do 1.55V on any AMD chip as long as your temps on 100% full load stay below ~60C at the highest... Besides, by the time ur cpu dies because u were running a heavy overclock @ high voltages and temperature, you would have upgraded. i have an AMD opteron 165 thats run its whole life on 1.5V and on the higher end of the thermometer and shes still running strong...
