Too low voltage harmful?

Hello

I recently started tweaking my 2500k and found out by Enabling PLL Overvoltage, LLC to 75% and putting CPU VTT to 1.20v (default was 1.10v) made me achieve above 4.4ghz speeds.

I'm currently testing 46x * 100 = 4.6Ghz, Vcore Offset +210mv gives me 111GFlops (Linpack with AVX).
But I'm experimenting undervolting and so far Offset +180mv gives me 110GFlops.

Now I would prefer lover voltage but is there any way that CPU gets harm with the fact I'm getting 1GFlops less thus the voltage might be slightly too low.

So, I could leave it at +210mv and Linpack reports 111Gflops.
Or I could leave it at +180mv and Linpack reports 110Gflops.

My next step is trying out +170, +160mv.

I might even aim for 4.7-4.8Ghz problem is that +180mv gives me 75/82/85/82/85c so Hottest core after Linpack is 85c.
