Memory Timing Config
► DRAM Timing Selectable
This item is used to enable/disable provision of DRAM timing by SPD device. The Serial
Presence Detect (SPD) device is a small EEPROM chip, mounted on a memory module. It
contains important information about the module's speed, si�e, addressing mode and various
other parameters, so that the motherboard memory controller (chipset) can better access the
memory.
When "DRAM Timing Selectable" is set to �Manual��, the following items can be set manually.
► CAS Latency Time (tCL)
This item controls the CAS latency, which determines the timing delay (in clock cycles) before
SDRAM starts a read command after receiving it.
► RAS# to CAS# Delay (tRCD)
This item allows you to select a delay time (in clock cycles) between the CAS and RAS strobe
signals.
► RAS# Precharge (tRP)
This item allows you to select the DRAM RAS precharge time (in clock cycles).
► Precharge Delay (tRAS)
This item allows you to set the precharge delay time (in clock cycles).
► Row Refresh Cycle (tRFC)
This item allows you to set Row Refresh Cycle (in clock cycles).
► Performance Level
This item allows you to set the performance level for your memory.
► Write to Precharge (tWR)
This item allows you to set Write to Precharge delay (in clock cycles).
► Write to Read Delay (tWTR)
This item allows you to set minimum Write-to-read delay (in clock cycles).
► Act to Act Delay (tRRD)
This item allows you to set Act to Act Delay (in clock cycles).
► Read to Precharge (tRTP)
This item is used to set the read CAS to precharge time (in clock cycles).
