▶ tRAS
This setting determines the time RAS takes to read from and write to memory cell.
▶ tRFC
This setting determines the time RFC takes to read from and write to a memory
cell.
▶ tWR
Minimum time interval between end of write data burst and the start of a precharge
command. Allows sense amplifiers to restore data to cells.
▶ tWTR
Minimum time interval between the end of write data burst and the start of a column-
read command. It allows I/O gating to overdrive sense amplifiers before read
command starts.
▶ tRRD
Specifies the active-to-active delay of different banks.
▶ tRTP
Time interval between a read and a precharge command.
▶ tFAW
This item is used to set the tFAW (four activate window delay) timing.
▶ tWCL
This item is used to set the tWCL (Write CAS Latency) timing.
▶ tCKE
This item is used to set the tCKE timing.
▶ tRTL
This item is used to set the tRTL timing.
▶ Advanced Channel 1/ 2 Timing Configuration
Press <Enter> to enter the sub-menu. And you can set the advanced memory timing
for each channel.
▶ GT OverClocking
This item allows you to enable/ disable the overclocking of integrated graphics.
▶ GT Ratio
This setting controls the ratio of integrated graphics frequency to enable the integrated
graphics to run at different frequency combinations.
▶ Spread Spectrum
When the mainboard's clock generator pulses, the extreme values (spikes) of the pulses
create EMI (Electromagnetic Interference). The Spread Spectrum function reduces the
EMI generated by modulating the pulses so that the spikes of the pulses are reduced
to flatter curves.
