Timing Mode

When set to auto mode, the system reads the electronic data sheet of the

Auto

 

memory modules and adjusts the timings accordingly.

MaxMemClk

 

When set to MaxMemClk, you can manually specify the memory clock

 

 

frequency independent of the system bus frequency.

 

 

 

 

Memory Clock value or Limit

Displays the current memory clock frequency.

 

 

 

 

CKE base power down

All synchronous memory devices can go into sleep mode as soon as the

Disabled

mode

clock enable (CKE) signal is disasserted. In that case, the internal clocks are

Enabled

 

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.

 

 

 

 

CKE based power down

Sets the CKE power saving through disasserting clock enable using system
