BIOS Setup
tRP
Controls number of cycles for RAS (row address strobe) to be allowed to pre-charge.
If nsu󰘲cent tme s allowed for RAS to accumulate before DRAM refresh, the DRAM
may fal to retan data. Ths tem apples only when synchronous DRAM s nstalled
n the system.
tRAS
Determnes the tme RAS (row address strobe) takes to read from and wrte to
memory cell.
tRFC
Ths settng determnes the tme RFC takes to read from and wrte to a memory
cell.
tWR
Determnes mnmum tme nterval between end of wrte data burst and the start of a
pre-charge command. Allows sense ampl󰘰ers to restore data to cell.
tWTR
Determnes mnmum tme nterval between the end of wrte data burst and the start
of a column-read command; allows I/O gatng to overdrve sense ampl󰘰es 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 Pulse Wdth for DRAM module.
tRTL
Ths tem s used to set Round Trp Latency settngs.
Advanced Channel 1/ 2 Tmng Con󰘰guraton
Press <Enter> to enter the sub-menu. And you can set the advanced memory tmng
for each channel.
MRC Fast Boot
Ths tem s used to enable/dsable MRC Fast Boot.
Spread Spectrum
Ths functon reduces the EMI (Electromagnetc Interference) generated by modulatng
clock generator pulses.
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
