Chipset Features Setup

Configure DRAM Timing by
Selects whether DRAM timing is controlled by the SPD (Serial Presence
Detect) EEPROM on the DRAM module. Setting to SPD enables CAS#
Latency, RAS# Precharge, RAS# to CAS# Delay and Precharge Delay
automatically to be determined by BIOS based on the configurations on the
SPD. Selecting Manual allows users to configure these fields manually.

CAS# Latency
This controls the timing delay (in clock cycles) before SDRAM starts a read
command after receiving it. Settings: 3 Clocks and 2 Clocks. 2 Clocks
increases the system performance while 3 Clocks provides more stable
performance.

RAS# Precharge
This item controls the number of cycles for Row Address Strobe (RAS) to be
