TYPE: HASEE K480N-I7D3, with graphics card type GT645M(GK107) DDR3. I want to overclock it for better performance. Using GPU-Z can't get it's vbios. There is no BIOS/VBIOS in HASEE's official website.I backup up the BIOS of mainboard from my notebook using aflash3. Need Help: How can i separate the vbios form the mainboard bios? How can i replace the vbios in mainboard bios? If I get the vbios,i can chang the para using Kepler BIOS Tweaker, right? PS: I load the bios image using MMTOOL Aptio, but i don't know which part is vbios? Then i exreact some large parts, open them with Kepler BIOS Tweaker, no one can discern by KBT. I get lenovo's GT650M and GT750M vbios, it can be discerned correctly by KBT.
