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*] 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. 4.4.5 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.
