BIOS Setup BIOS Setup
▶ Advance DRAM Configuraton
Press <Enter> to enter the sub-menu and the followng screen appears.
▶ 1N/2N Memory Tmng
Ths tem controls the SDRAM command rate. Select [1N] makes SDRAM sgnal
controller to run at 1N (N=clock cycles) rate. Selectng [2N] makes SDRAM sgnal
controller run at 2N rate.
▶ CAS# Latency (CL)
Ths controls the CAS latency, whch determnes the tmng delay (n clock cycles)
before SDRAM starts a read command after recevng t.
▶ tRCD
When DRAM s refreshed, both rows and columns are addressed separately. Ths
setup tem allows you to determne the tmng of the transton from RAS (row ad-
dress strobe) to CAS (column address strobe). The less the clock cycles, the faster
the DRAM performance.
▶ tRP
Ths settng controls the number of cycles for Row Address Strobe (RAS) to be
allowed to precharge. If nsufficent tme s allowed for the RAS to accumulate ts
charge before DRAM refresh, refresh may be ncomplete and DRAM may fal to
retan data. Ths tem apples only when synchronous DRAM s nstalled n the sys-
tem.
▶ tRAS
Ths settng determnes the tme RAS takes to read from and wrte to memory cell.
▶ Advanced Memory Settng
Settng to [Auto] enables DRAM tmngs automatcally to be determned by BIOS
based on the configuratons on the SPD (Seral Presence Detect) EEPROM on the
DRAM module.
▶ Extreme Memory Profile
Ths tem s used to enable/dsable the Intel Extreme Memory Profile (XMP). For further
nformaton please refer to Intel's offical webste.
▶ Memory Rato
Ths tem allows you to set the memory multpler.
▶ Adjusted DRAM Frequency (MHz)
It shows the adjusted Memory frequency. Read-only.
▶ ClockGen Tuner
