**I've tried to overclock my Intel HD Graphics 4600 in my desktop PC.**

I've read elsewhere;
people managed to get **1600-1700MHz (OC)** instead of **1250-1300MHz (default)**.

**The problem here is I am not unable to get reliable consistent results.**

At some point I was able to get a decent record, but I'm unsure whether it was *"Adaptive"* or *"Static"* voltage as the **Intel Extreme Tuning Toolkit** sometimes changes this setting.

**I used FurMark for these records**

```

427 - 1600MHz (+0.085V)
428 - 1600MHz (+0.095V)
435 - 1600MHz (+0.095V)
415 - 1650MHz (+0.165V)
426 - 1650Mhz (+0.175V)
426 - 1650MHz (+0.180V)
```

What I am thinking I am battling here is either some adaptive voltage or auto scaling.

It's quite random whether I can reproduce the results above or not.

Quite recently I even have problems reaching in the 400+ score (most scores drops below, even while being overclocked), which was not at all a problem earlier.

Without overclock as you can see the scores are from 350-400.
