(N=Newbie, E=Hardware Enthusiast, O=Overclocker, B=Budget)
V. Settings are changed, and BIOS is saved, or is it?
Most enthusiasts will change the settings in the BIOS, hit F10 and hit "Y" when prompted to save the settings and they will go on their merry way booting the OS. But the thing is, this doesn't always work. It does work on changing memory ratio, setting boot priority and all other hosts of changes however, on the option that actually overclock the motherboard, chances are, the changes never took effect and yet it is displayed in the BIOS when you did checked it the next time around.
You can verify this by following the steps below:
- Boot up and enter the BIOS by pressing F2 in the boot up screen
- Go to "Advanced" -> "Hardware Monitoring"
- Note and write the value you see on the Vccp
- Now, go to "Advanced" -> "Chipset Configuration"
- Go to "Default Configuration Override"
- On "Do you wish to continue?" settings, just select "Yes"
- On "Default CPU VID", change it to "Disable" (Note: Unless XE CPU is used, this is not available if hard modding is not made. See previous page for hard modding)
- Record the current value on "CPU VID" before changing it, say, two notches lower or higher.
- Save and reboot
- Again, Go to "Advanced" -> "Hardware Monitoring"
You'll see that the values reported by "Hardware Monitoring" is still the same, that is because, vCore changes isn't set, yet. Now, what is the work around? Simple, shut it down, and ensure you remove the power from the outlet. That is, no standby power must be on the motherboard, zero current. Now, if you do this and followed steps 1-10 again, you'll see that changes has finally taken effect.
