4-18 Chapter 4: BIOS setup
Pri. Information: 6-6-6-15-4-36-6-4
The values vary depending on your settings of the following sub-items:
CAS# Latency [5 DRAM Clocks]
Configuration options: [5 DRAM Clocks] [6 DRAM Clocks] [7 DRAM Clocks]
[8 DRAM Clocks] [9 DRAM Clocks] [10 DRAM Clocks] [11 DRAM Clocks]
RAS# to CAS# Delay [5 DRAM Clocks]
Configuration options: [3 DRAM Clocks] [4 DRAM Clocks]~[17 DRAM Clocks]
[18 DRAM Clocks]
RAS# Precharge [5 DRAM Clocks]
Configuration options: [3 DRAM Clocks] [4 DRAM Clocks]~[17 DRAM Clocks]
[18 DRAM Clocks]
RAS# Active Time [15 DRAM Clocks]
Configuration options: [3 DRAM Clocks] [4 DRAM Clocks]~[33 DRAM Clocks]
[34 DRAM Clocks]
RAS# to RAS# Delay [Auto]
Configuration options: [Auto] [1 DRAM Clocks]~[15 DRAM Clocks]
The DRAM Frequency configuration options vary with the FSB Frequency
settings.
• Selecting a very high DRAM frequency may cause the system to become
unstable! If this happens, revert to the default setting.
• DDR3-667 help: DRAM frequency lower than 800 MHz may cause system
boot failure due to spec violation.
4.4.4 DRAM Frequency [Auto]
Allows you to set the DDR3 operating frequency.
Configuration options: [Auto] [DDR3-667 MHz] [DDR3-800 MHz] [DDR3-835MHz]
[DDR3-887 MHz] [DDR3-1002MHz] [DDR3-1066MHz] [DDR3-1111] [DDR3-1333]
[DDR3-*1600 MHz*] [DDR3-*1800 MHz*]
4.4.5 DRAM Command Rate [Auto]
Configuration options: [Auto] [1T] [2T]
4.4.6 DRAM Timing Control [Auto]
Configuration options: [Auto] [Manual]
• The following sub-items apprear only when you set the DRAM Timing
Control item to [Manual].
• The configuration options for some of the following items vary depending
on the DIMMs you install on the motherboard.
