UEFI: BIOS gets a new lookAfter years and years of using a very old fashioned design within our BIOS now we're able to see something different. Sandy Bridge based motherboards introduced a whole new look which allows you to see colors and images within the BIOS settings. UEFI allows manufacturers to add graphs or charts along with images and scroll bars that can be moved within your mouse or keyboard. While I still prefer my old and trusty keyboard, I'm pretty sure this is a big step for the future of the motherboards. I should add that not all the motherboard manufacturers jumped to the EFI wagon, but I can see them jumping near in the future.
On the image above we can see CPU multiplier, PLL Overvoltage and LLC, which as I explained in the last section, are key-values to obtain high clocks. In the image below we can also see CPU Voltage, VCCSA, VCCIO and DRAM voltage.
Some manufacturers like ASUS will give you the opportunity to modify CPU current and power limits in order to achieve higher stability and clocks when adding voltage to your CPU. Try using them when your motherboard seems to be restarting by a factor that might not be stability, but more like a whole restart given by the motherboard limits. Now that we've seen the new EFI interface, let's move on to the P67 test platform.
