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.
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.
