I have recently taken over the site biosmods.com which is a forum specialising in bios modding
I had a look around in the Acer E380 R01B4 Original Bios and it turns out that the overclocking options were just hidden from view , not completely removed. Major oems like hp dell and acer hide these options to save expensive tech support costs trying to help people who have messed with their bios.
I have unlocked all of the available hidden options from the original bios
You can now attempt to overclock this system!!
Options avaialble include:
Cpu frequency (FSB)
DRAM Configuration (Overclock Memory)
NPT Vid Control (Voltage)
NPT Fid Control(Voltage)
Please note that reflashing with this bios WILL void your machines warranty and could potentially damage the motherboard. Bios flashing is a risky process and you should be prepared for the worst if you want to flash this . I wont take any responsibility if you break the computer as i am merely providing the download link. It is up to you whether you download and flash this bios.
