Need help with acer bios

[C2L]

I have an acer veriton vx498g (lga 1156) and I would love to unlock more of the BIOS settings. Especially the ability to overclock and/or change voltages. I don't believe this BIOS is from American megatrends or Phoenix, it says it's a BIOS made exclusively for Acer, so custom? 

Note: h57 chipset does allow overclocking on non oem boards

thanks in advance

note note: do I turn off spread spectrum/any other settings to overclock?
