[SOLVED] Best way to check system stability after undervolting?

Solution
Linpack Extreme or Ycruncher. Linpack places a heavy load on RAM and CPU. Ycruncher puts a load on RAM, can't remember how hard it hammers CPU but probably a decent amount.
For pure CPU, OCCT or Prime95.
I prefer to do initial stability testing after booting WinPE so that instability can't corrupt my system. There are a number of tools that run under WinPE, like AIDA64...
