Dynamic Memory Boost Allows you to enable or disable Dynamic Memory Boost feature. You can automatically switch between the default SPD Profile frequency and the selected XMP profile frequency. Only valid if an XMP Profile is selected. Configuration options: [Enabled] [Disabled] Realtime Memory Frequency Allows you to enable or disable Realtime Memory Frequency feature. You can manually switch in runtime between the default SPD Profile frequency and the selected XMP profile frequency. Only valid if an XMP Profile is selected. Configuration options: [Enabled] [Disabled] DRAM Reference Clock Allows you to configure DRAM Reference Clock. Select [Auto] for optimized settings. Configuration options: [Auto] [100MHz] [133MHz] DRAM Frequency If [Auto] is selected, the motherboard will detect the memory module(s) inserted and assign the appropriate frequency automatically. DRAM Gear Mode Allows you to select the DRAM Gear Mode. High gear is good for high frequency. Configuration options: [Auto] [Gear 2] [Gear 4] BCLK Frequency The CPU speed is determined by the CPU Ratio multiplied with the BCLK. Increasing the BCLK will increase the internal CPU clock speed but also affect the clock speed of other components. Primary Timing CAS# Latency (tCL) The time between sending a column address to the memory and the beginning of the data in response. RAS# to CAS# Delay (tRCD) RAS# to CAS# Delay : The number of clock cycles required between the opening of a row of memory and accessing columns within it. 36

Dynamic Memory Boost
Allows you to enable or disable Dynamic Memory Boost feature. You can automatically
switch between the default SPD Profile frequency and the selected XMP profile frequency.
Only valid if an XMP Profile is selected.
Configuration options: [Enabled] [Disabled]
Realtime Memory Frequency
Allows you to enable or disable Realtime Memory Frequency feature. You can manually
switch in runtime between the default SPD Profile frequency and the selected XMP profile
frequency. Only valid if an XMP Profile is selected.
Configuration options: [Enabled] [Disabled]
DRAM Reference Clock
Allows you to configure DRAM Reference Clock. Select [Auto] for optimized settings.
Configuration options: [Auto] [100MHz] [133MHz]
DRAM Frequency
If [Auto] is selected, the motherboard will detect the memory module(s) inserted and assign
the appropriate frequency automatically.
DRAM Gear Mode
Allows you to select the DRAM Gear Mode. High gear is good for high frequency.
Configuration options: [Auto] [Gear 2] [Gear 4]
BCLK Frequency
°e CPU speed is determined by the CPU Ratio multiplied with the BCLK. Increasing the
BCLK will increase the internal CPU clock speed but also affect the clock speed of other
components.
Primary Timing
CAS# Latency (tCL)
°e time between sending a column address to the memory and the beginning of the data
in response.
RAS# to CAS# Delay (tRCD)
RAS# to CAS# Delay : °e number of clock cycles required between the opening of a row of
memory and accessing columns within it.
