Hi guys, I have one little question but bigger trouble, i think: How can I unlock all options inside the BIOS??? U know, with almost laptops, almost options are lock eg: Multiplier, bus speed or Voltage... But i think they (Manufacturers) just lock them to protect the laptop, it means we still can unlock them, right? My laptop is Lenovo Y450-4189 with Phoenix BIOS CPU is C2D T6600 @2.2GHz cache 2MB bus 800MHz 2x2GB RAM Elpida with bus 1333MHz but they are running with bus 400, why? see its profiles i think it can run faster, someone tells me the reason is the FSB of CPU, it is just only 800MHz, and locked, so that they (RAM) can only run with 400Mhz!!?? I think i can't resolve this with my short knowledge, plzz give me advices, Upgrade CPU or request some one to unlock bios options, or change RAMs Thankx for reading and helping!
