Very often people send me rma requests for stability issues even in brand new hardware.
Quick rule of thumb if your using more than one dim of ram a minor ram voltage bump can work magic on your system. Going from 1.65 or 1.35 to 1.66 or 1.36 can solve a good sum of issues.
Same wIth cpus bumping them up just slightly can be the difference from a bsod and a happy rig.
all voltage bumps should be done in the bios and stress tested after.
