[XMP Profile 1]-Configuration database of using XMP timing profile 1.
[XMP Profile 2]- Configuration database of using XMP timing profile 1.
The following items appear only when the option is set to “Manual”.
► Memory Clock Multiplier
This item is used to set the memory clock multiplier.
► Memory Multiplier
This item is used to set the memory multiplier ratio.
► CAS# Latency(tCL)
This item dispalys the CAS Latency time. The CAS Latency is the number of clock cycles that
elapse from the time the request for data is sent to the actual memory location until the data is
transmitted from the module.
► Row Precharge Time(tRP)
This item dispalys the DRAM RAS precharge time (in clock cycles).
► RAS# to CAS# Delay(tRCD)
This item dispalys the delay time (in clock cycles) between the CAS and RAS strobe signals.
► RAS# Active Time(tRAS)
This item dispalys the precharge delay time (in clock cycles).
► Write Recovery Time(tWR)
This item allows you to select the write recovery time (in clock cycles).
► Row Refresh Cycle Time(tRFC)
This item allows you to select the minimum refresh recovery time (in clock cycles).
► Write to Read Delay (tWTR)
This item allows you to set minimum Write-to-read delay (in clock cycles).
► Active to Active Delay (tRRD)
This item allows you to set Active to Active Delay (in clock cycles).
► Read CAS# Precharege(tRTP)
This item is used to set the read CAS to precharge time (in clock cycles).
►Four Active Window Delay(tFAW)
This item is used to set the four active window delay time (in clock cycles).
