Z390 Steel Legend
Configure the frequency of the integrated GPU.
DRAM Configuration
DRAM Tweaker
Fine tune the DRAM settings by leaving marks in checkboxes. Click OK to confirm and
apply your new settings.
DRAM Timing Configuration
Load XMP Setting
Load XMP settings to overclock the memory and perform beyond standard specifications.
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.
DRAM Reference Clock
Select Auto for optimized settings.
DRAM Frequency
If [Auto] is selected, the motherboard will detect the memory module(s) inserted
and assign the appropriate frequency automatically.
DRAM Clock
Choose a frequency to override to clock delay for memory training. DRAM Clock
controls memory training only if ASRock Timing Optimization is disabled.
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 and Row Precharge (tRCDtRP)
RAS# to CAS# Delay : °e number of clock cycles required between the opening of a row
of memory and accessing columns within it.
Row Precharge: °e number of clock cycles required between the issuing of the precharge
command and opening the next row.
