Actually I just noticed that the newest F2 Bios for the Gigabyte MA790GP-UD4H actually does have 2 visual changes:

1. ACC is now on the normal menu. (No need to use the CTRL-F1)

2. They have added a new BIOS setting called:

EC Firmware for Advanced Clock Calibration.

It can be set to the following:

Normal = Used AMD normal EC Firmware for Advanced Clock Calibration
Hybrid = Used AMD particular EC Firmware for Advanced Clock Calibration


So... what is "AMD particular" as opposed to normal? Anyone have any ideas??
