tRFC
Ths settng determnes the tme RFC takes to read from and wrte to a memory
cell.
tWR
Mnmum tme nterval between end of wrte data burst and the start of a precharge
command. Allows sense ampl󰘰ers to restore data to cells.
tWTR
Mnmum tme nterval between the end of wrte data burst and the start of a column-
read command. It allows I/O gatng to overdrve sense ampl󰘰ers before read
command starts.
tRRD
Spec󰘰es the actve-to-actve delay of d󰘯erent banks.
tRTP
Tme nterval between a read and a precharge command.
tFAW
Ths tem s used to set the tFAW (four actvate wndow delay) tmng.
tWCL
Ths tem s used to set the tWCL (Wrte CAS Latency) tmng.
tCKE
Ths tem s used to set the tCKE tmng.
tRTL

Press <Enter> to enter the sub-menu. And you can set the advanced memory tmng
for each channel.
Spread Spectrum
When the manboard’s clock generator pulses, the extreme values (spkes) of the pulses
create EMI (Electromagnetc Interference). The Spread Spectrum functon reduces the
EMI generated by modulatng the pulses so that the spkes of the pulses are reduced
to 󰘱atter curves.
Important
If you do not have any EMI problem, leave the settng at [Dsabled] for optmal system
stablty and performance. But f you are plagued by EMI, select the value of Spread
Spectrum for EMI reducton.
The greater the Spread Spectrum value s, the greater the EMI s reduced, and the
system wll become less stable. For the most sutable Spread Spectrum value, please
consult your local EMI regulaton.
Remember to dsable Spread Spectrum f you are overclockng because even a slght
jtter can ntroduce a temporary boost n clock speed whch may just cause your
overclocked processor to lock up.
