Bios Mods -The Best BIOS Update and Modification Source

Hello!

I'm new here so first i'd like to welcome everybody

I bought an Acer Aspire M5201 nearly 2 years ago and wanted to overclock the Cpu but i couldnt see any oc options in my bios so i updated it from R01-B2 to B3 but the oc options were still not in there so i updated it to B4 and the same thing ! the oc options are hidden somehow.Finally i updated it to R01-C0 but nothing changed :/ I tried to press Ctrl+F1,Ctrl Home,Ctrl Insert,Ctrl F9 and Ctrl F12 but like before nothing changed
So i thought maybe you guys can help me.
I know Acer Motherboard is not specially for overclocking but i wanted to overlock my cpu from 2,49ghz to 2,6 so its not so much.

Motherboard:Acer RS780HVF
Cpu:Amd Phenom x4 9750 2,49ghz
Ram:4gb Kingston
btw. Sorry for my English : D I hope that you guys understand me

Help!
