Ok so Im a little confused here. My motherboard is the z87-plus from asus. the bios firmware was 1505 and i updated it to 1707 from asus drivers website. Now what I notice is that my core voltage does not change based on the load it is constantly 1.265v. I intentionally set the core voltage to 1.265v when the firmware was 1505 and the voltage would drop under 1v when at idle and jump up when in use. Now with firmware 1707 the core voltage stays at 1.265v even at idle or load. So what is causing this to happen. Thank you for your help and i appreciate it.
