Request BIOS unlock ASUS K45A laptop

[CapeWrath]

Hello!
First of all, I'm new to the forums so I'm sorry if i break any rules about posting. Also, english is not my first language, sorry for grammar mistakes.

So, i just got a "new" laptop with an Ivy Bridge core i5 3210m and Intel HD Graphics 4000 but it's performance for gaming and video editing is a little bit under what i expected and as my laptop usually runs very cool I would like to try some overclocking. I've downloaded Intel Extreme Tuning Utility, but unlike my Haswell desktop all the options and sliders are grayed out, so i'm assuming the BIOS is locked because i've sucessfully performed overclocks in another models with intel HD Graphics.

Searching the web i found that this is the best place to look for custom BIOS, but unfortunately i couldn't find my model anywhere, so i would like to ask for some help on the subject, since i don't even know if its possible to overclock this model.

I recently update my bios from the official link here : dlcdnet.asus.com/pub/ASUS/nb/K45A/K45VMAS234.zip?_ga=1.245327425.518893331.1433086744

I would really appreciate any help.
