The board has an IC controller that they call the ECU.
I suppose it's part of the Green Push to "Save the environment"

"ASUS Exclusive EPU Saves Up to 80.23%CPU Power
The ASUS-developed EPU is the world´s first hardware-based on-demand power
saving IC controller. This new generation automatic energy saving chip
utilizes an innovative power technology to digitally monitor and
automatically fine-tune the CPU power supply with improved VRM efficiency
under any loading. With real-time automatic detection of the CPU current,
the EPU can provide total control and attain the best possible power
efficiency and astounding energy savings to help save the environment -
providing users with more power for higher performance and saving up to
80.23% CPU power when the PC is running low intensity programs. Coupled with
the innovative AI Gear3 - which features a new user interface that shows
users exactly how much electricity and CO2 is being saved, the ASUS EPU can
provide users with up to 50% enhanced power efficiency."

The article here, makes reference to variable usage of phases on the
Vcore regulator.

Hmmm. "Environmental Protection Unit"? May be some power-saving
thing. In that case you should install it, unless it causes
problems.
