X299 Killer SLI/ac
Long Duration Maintained
Configure the period of time until the CPU ratio is lowered when the Long
Duration Power Limit is exceeded.
Short Duration Power Limit
Configure Package Power Limit 2 in watts. When the limit is exceeded, the CPU
ratio will be lowered immediately. A lower limit can protect the CPU and save
power, while a higher limit may improve performance.
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 DDR 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 Frequency
If [Auto] is selected, the motherboard will detect the memory module(s) inserted
and assign the appropriate frequency automatically.
DRAM Reference Clock
Select Auto for optimized settings.
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.
