When this item is enabled, the DRAM timing parameters are set according
to the DRAM SPD (Serial Presence Detect). When disabled, you can
manually set the DRAM timing parameters through the DRAM sub-items.
The following sub-items appear when this item is Disabled. Configuration
options: [Disabled] [Enabled]
