& Rank Interleaving
Enables or disables memory rank interleaving. Enabled allows the system to simultaneously access different
ranks of the memory to increase memory performance and stability. Auto lets the BIOS automatically
congurethissetting.(Default:Auto)
& Memory Boot Mode
Provides memory detection and training methods.
Auto    LetstheBIOSautomaticallycongurethissetting.(Default)
Normal The BIOS automatically performs memory training. Please note that if the system
becomes unstable or unbootable, try to clear the CMOS values and reset the board
todefaultvalues.(Refertotheintroductionsofthebattery/clearCMOS_SWjumper
in Chapter 1 for how to clear the CMOS values.)

Misc Timing Control
These sections provide memory timing settings. Note: Your system may become unstable or fail to boot
after you make changes on the memory timings. If this occurs, please reset the board to default values by
loading optimized defaults or clearing the CMOS values.
