System Voltage Control
Determines whether to manually set the system voltages. Auto lets the BIOS automatically set the
system voltages as required. Manual allows all voltage control items below to be congurable. (Default:
Auto)
CPU PLL Voltage Control
Allows you to set the CPU PLL voltage.
Normal Supplies the CPU PLL voltage as required. (Default)
2.220V ~ 3.100V The adjustable range is from 2.220V to 3.100V.
Note: Increasing CPU voltage may result in damage to your CPU or reduce the useful life of the CPU.

DQS drive Strength
Options are: Auto (default), 0.75x, 1.0x, 1.25x, 1.5x.
Data drive Strength
Options are: Auto (default), 0.75x, 1.0x, 1.25x, 1.5x.
MEMCLK drive Strength

Addr/Cmd drive Strength
Options are: Auto (default), 1.0x, 1.25x, 1.5x, 2.0x.
CS/ODT drive Strength
Options are: Auto (default), 1.0x, 1.25x, 1.5x, 2.0x.
CKE drive Strength
Options are: Auto (default), 1.0x, 1.25x, 1.5x, 2.0x.
Bank Interleaving
Enables or disables memory bank interleaving. Enabled allows the system to simultaneously access dif-
ferent banks of the memory to increase memory performance and stability. (Default: Enabled)
Channel interleave
Enables or disables memory channel interleaving. Enabled allows the system to simultaneously access
different channels of the memory to increase memory performance and stability. (Default: Enabled)
DQS Training Control
Enables or disables memory DQS training each time the system restarts. (Default: Skip DQS)
CKE Power Down Mode
Determines whether to set the memory to power down mode when the CKE pin is closed. (Default: Dis-
abled)
Memclock tri-stating
Determines whether to enable memory clock tri-stating in CPU C3 or Alt VID mode. (Default: Disabled)
