DDR Controller Configuration
DDR Power Options
Power Down Enable
本項目用來開啟或關閉 DDR 斷電模式。 設定值
有：[Disabled] [Enabled] [Auto]
Infinity Fabric Frequency and Dividers
Infinity Fabric Frequency and Dividers
本項目可以設定 Infinity Fabric Frequency（FCLK）。 Auto = FCLK
= MCLK。多數情況下 Manual = FCLK 需小於 MCLK 以獲得最佳效
能。當 FCLK 與 MCLK 不協調時會發生延遲，但充足的高 MCLK 可
以解決延遲或使其無效。設定值有：[Auto] [100MHz] - [2000MHz]
UCLK DIV1 MODE
本項目用來設定 UCLK DIV 模式。設定值有：[Auto]
[UCLK=MEMCLK] [UCLK=MEMCLK/2]
