BIOS Setup
- 51 -
& Channel Interleaving
Enables or disables memory channel interleaving. Enabled allows the system to simultaneously access
different channels of the memory to increase memory performance and stability. Auto lets the BIOS
automaticallycongurethissetting.(Default:Auto)
& 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

& Memory Boot Mode
Provides memory detection and training methods.

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jumperin
Chapter 1 for how to clear the CMOS values.)

& Memory Enhancement Settings
Provides several memory performance enhancement settings: Auto, Relax OC, Enhanced Stability, Normal
(basic performance), Enhanced Performance, High Frequency, High Density, and DDR-4500+. (Default:
Auto)
