Description
Option
Timing Mode
When set to auto mode, the system reads the electronic data sheet of the
memory modules and adjusts the timings accordingly.
When set to MaxMemClk, you can manually specify the memory clock
frequency independent of the system bus frequency.
Auto
MaxMemClk
Memory Clock value or Limit
Displays the current memory clock frequency.
CKE base power down
mode
All synchronous memory devices can go into sleep mode as soon as the
clock enable (CKE) signal is disasserted. In that case, the internal clocks are
disabled and the memory chip goes into auto-refresh mode which is the
lowest power state at which the memory retains data.
If then power is turned off, the device will lose all data, however, as long as
standby power is maintained, no data loss will occur.
Disabled
Enabled
CKE based power down
Sets the CKE power saving through disasserting clock enable using system
level or per channel basis.
Per Channel
Per CS
Memclock tri-stating
Enables or disables the memory clock tri-stating during C3 an Alt VD
feature.
Disabled
Memclock tri-
stating during
C3 and Alt VD
Memory Hole Remapping
Enables or disables memory remapping around the memory hole.
Enabled
Disabled
Auto Optimize Bottom IO
Allows you to auto optimize maximal memory size when kernel assigns PCI
Resources.
