DRAM Timing Selectable
Selects whether DRAM timing is controlled by the SPD (Serial Presence Detect)
EEPROM on the DRAM module. Setting to [By SPD] enables DRAM timing to
be determined automatically by BIOS based on the configurations on the SPD.
Selecting [Manual] allows users to configure these fields manually.
CAS Latency Time
This controls the timing delay (in clock cycles) before SDRAM starts a read
command after receiving it. Settings: [1.5], [2], [2.5] (clocks). [1.5] (clocks)
increases the system performance the most while [2.5] (clocks) provides the
most stable performance.
Active to Precharge Delay
The field specifies the idle cycles before precharging an idle bank.
DRAM RAS# to CAS# Delay
This field allows you to set the number of cycles for a timing delay between the
CAS and RAS strobe signals, used when DRAM is written to, read from or
