Configure DRAM Timing by SPD [Enabled]
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
Performance Acceleration Mode [Auto]
This field when [Enabled] minimize latencies from CPU to memory to boost system performance. Configuration options: [Auto] [Enabled]
Setting to [Enabled] may cause the system to become unstable! If this happens, revert to the default setting [Auto].
DRAM Idle Timer [Auto]
Configuration options: [Infinite] [0T] [8T] [16T] [64T] [Auto]
DRAM Refresh Mode [Auto]
Configuration options: [Auto] [15.6 uSec] [7.8 uSec] [64 uSec] [64T]
If the system becomes unstable after changing the settings of any of the above items, revert to the default settings.
