Cannot Set IGD Minimum Memory to 1024MB or 2048MB on Intel® NUC Kit





What are you seeing?

The Intel® NUC Kit NUC6i7KYK doesn't allow you to select 1024MB or 2048MB as the IGD Minimum Memory if you enable the Thunderbolt™ Controller in BIOS Setup.

Why are you seeing it?

Because the Thunderbolt Controller uses up to 2048MB IGD Minimum Memory from PCIE resources.

How to fix it

Disable the Thunderbolt Controller:

  1. Press F2 during boot to enter BIOS Setup.
  2. Go to Advanced > Devices > Onboard Devices.
  3. Disable (uncheck) Thunderbolt Controller.
  4. Press F10 to save and exit BIOS Setup.


Note The 2048MB option for the IGD Minimum Memory setting in BIOS was added with BIOS version 0045.
