Acer Aspire V3 771G 6485 need help with unlocked Bios

[Overdose26]

Hi guys. Need some help/advice.

So i did flash to unlocked bios 2.28 with recovery method all good.
I was thinking that when im gonna use unlocked bios its gonna let me Overclock my
Geforce GT 730 more. What i mean its the +135 mhz limit in nvidia inspector.
But i still have this limit and dont know what to do? I did see at some site some people did push the GPU to almost 1 Ghz.

I read something about vbios? where i supposed to get it? and what to do with it?

Thats my main concern.

Other thing is at advanced options in bios , are there options to change to get better overall perfomance / boot time etc?

Btw i did use Firecode95 bios.

Thank You
