I just finished building a new mini-ITX build with the Fatal1ty Z170 motherboard. In the UEFI/BIOS are a few options about which I have questions:

FCLK FREQUENCY -- is that irrelevant if I'm not using a discrete graphics card? I understand there is some discussion whether the setting should be 800Mhz or 1.0Ghz on a desktop computer (default is 800Mhz), but do I even care when I'm using the iGPU?

PACKAGE C STATE SUPPORT -- "Enable CPU, PCIe, memory, graphics C State Support for power savings" -- is disabled by default. Is there any reason to NOT enable it?

PCIE ASPM SUPPORT
PCH PCIE ASPM SUPPORT
DMI ASPM SUPPORT
PCH DMI ASPM SUPPORT
-- all are disabled by default. Again, any reason NOT to enable them?

DEEP SLEEP -- "We recommend disabling Deep Sleep for better system compatibility and stability." Most of the articles I find Googling deep sleep deal with Realtek network controllers. On this motherboard (with Intel Ethernet LAN and Broadcom WiFi) what does deep sleep refer to?
