BIOS Setup
RAS to CAS Delay (Trcd)
When DRAM refreshes, both rows and columns are addressed
separately. This field is used to select the delay time from RAS (Row
Address Strobe) to CAS (Column Address Strobe) when reading
and writing to the same bank. The lesser the clock cycle, the faster
the DRAM’s performance.
Row Precharge Time (Trp)
The field is used to select the row precharge time, precharge to
active or auto-refresh of the same bank.
RAS to RAS Delay (Trrd)
This field is used to select the delay time from RAS (Row Address
Strobe) to the next RAS (Row Address Strobe) when reading to the
same bank. The lesser the clock cycle, the faster the DRAM’s per-
formance.
Row Cycle Time (Trc)
This field is used to select the row cycle time, RAS# active or auto
refresh of the same bank.
DIMM 1 Row Refresh (Trfc0) to DIMM 4 Row Refresh (Trfc3)
This field is used to select the row refresh cycle time of DIMM 1 to
DIMM 4.
Read Precharge Time (Trtp)
The options are Auto, 002 CLK and 003 CLK.
Write Recovery Time (Twr)
This field is used to select the write recovery time when the DRAM
safely registers the last write data. This is the time from the last write
data to precharge.
