NO! Why are you recommending this? This is not gonna be stable.
1.7V is too high for Sandy Bridge. You need to lower to at least 1.65V. Set the voltage to 1.65V and try to mirror the results Tom's Hardware got (1600@7-8-7-15) or what TweakTown got (1800@9-9-9-24). Out of the two, I'd go with 1800MHz. All newest architectures benefit more from frequency increase than timing increase, which is WAY over-rated.
