I7 2600k integrated gpu overclock

[firestone9x]

I auto tuned my 2600k with ASUS AI SUITE 2 and got my igpu offset voltage increased to 0.25V and max frequency to 1650Mhz.

After playing around with the igpu frequency I got a stable 1850Mhz with 0.25V.

Is it possible to increase the igpu voltage (without damaging the cpu) to reach higher frequencies.

Help much appreciated

it would become risky..
