Most likely will survive 1 month, or more than 1 month. If it survives from day 8 to day 14 on 1.7 vTT, will you again increase it to 1.8v on the 15th day and so on?

Honestly, at that voltage, you will probably be waiting awhile for it to die. You need choices up to 6 months at least at those voltages.

If you really want to kill it, set 2.0v vTT, and then your choices for the timescale of it's death will be more relevant.
