to Enabled, it will enhance overall system performance by providing direct memory
access for data transferring. The options are Enabled and Disabled.
Coarse-Grained Clock Gating

IO Hub (IOH). When this feature is set to Disabled, all clocks on the die of the IOH
chip will be disabled except for the Intel management engine (Intel ME) subsystem.
Any non ME clocks left running will detect events to restore clock to the whole die.
When this feature is set to Enabled, all clocks on the die will be enabled to maximize
power effi ciency. The options are Enabled and Disabled.
