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.
