Z490 Steel Legend ratio will be lowered immediately. A lower limit can protect the CPU and save power, while a higher limit may improve performance. CPU Core Current Limit Configure the current limit of the CPU core. A lower limit can protect the CPU and save power, while a higher limit may improve performance. GT Current Limit Configure the current limit of the GT slice. 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. Memory Information Allows users to browse the serial presence detect (SPD) and Intel extreme memory profile (XMP) for DDR4 modules. DRAM Timing Configuration Load XMP Setting Load XMP settings to overclock the memory and perform beyond standard specifications. DRAM Frequency If [Auto] is selected, the motherboard will detect the memory module(s) inserted and assign the appropriate frequency automatically. 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 and Row Precharge (tRCDtRP) RAS# to CAS# Delay : The number of clock cycles required between the opening of a row of memory and accessing columns within it. Row Precharge: The number of clock cycles required between the issuing of the precharge command and opening the next row. 61 English
