For setting DRAM Timing, By SPD is following Intel PC DDR SDRAM Serial
Presence Detect Specification.
Options : Manual, By SPD.
CAS Latency Time
Enables you to select the CAS latency time. The value is set at the factory
depending on the DRAM installed. Do not change the values in this field unless
you change specifications of the installed DRAM and DRAM clock from DRAM
Timing Selectable. The default is by DRAM SPD.
Options : 1.5,2, and 2.5.
Active to Precharge Delay
This item specifies the number of clock cycles needed after a bank active command
before a precharge can occur (sets the minimum RAS pulse width.). The default is
by DRAM SPD.
Options : 5,6,7.
DRAM RAS# to CAS# Delay
This item sets the timing parameters for the system memory such as the CAS
(Column Address Strobe) and RAS (Row Address Strobe). The default is by
DRAM SPD.
Options :2,3.
DRAM RAS# Precharge
This item refers to the number of cycles required to return data to its original
location to close the bank or the number of cycles required to page memory before
the next bank activate command can be issued. The default is by DRAM SPD.
Options :2,3.
Turbo Mode
Enable you to set the system to enter “ Turbo “ mode. The default is “ Disabled “ .
Memory Frequency For
Enable you to set the memory frequency for the installed memory. Select “ Auto
“ ( default ) to enable the system to set the memory frequency automatically
according to the installed DRAM.
