Tesla V100 Operation Voltage

Hi Experts,

Tesla V100 specifies the operation voltage range 12 ± 8%. Is it possible to work at some wider voltage range, such as 14V ? I tried with 14V DC source, V100 failed to boot.

Since the supply voltage cannot be changed easily, could I do some rework (or adjust V100 setting option) on V100 to operate at a higer(or lower) voltage?
