SDRAM CAS Latency
This item adjusts the speed it takes for the memory module to complete a
command. Generally, a lower setting will improve the performance of your
system. However, if your system becomes less stable, you should change it to a
higher setting. This field is only available when “DRAM Timing” is set to “Manual”.
Settings: [1.5/2, 2/3, 2.5/4, 3/5]
Bank Interleave
Set the interleave mode of the SDRAM interface. Interleaving allows banks of
SDRAM to alternate their refresh and access cycles. One bank will undergo its
refresh cycle while another is being accessed. This improves performance of the
SDRAM by masking the refresh time of each bank. This field is only available
when “DRAM Timing” is set to “Manual”.
Settings: [Disabled, 2 Bank, 4 Bank, 8 Bank]
Precharge to Active (Trp)
This field controls the length of time it takes to precharge a row in the memory
module before the row becomes active. Longer values are safer but may not offer
the best performance. This field is only available when “DRAM Timing” is set to
“Manual”.
Settings: [2T - 5T]
Active to Precharge (Tras)
This field controls the length of time it a row stays active before precharging.
Longer values are safer but may not offer the best performance. This field is only
available when “DRAM Timing” is set to “Manual”.
Settings: [5T – 20T]
Active to CMD (Trcd)
This field is only available when “DRAM Timing” is set to “Manual”.
Settings: [2T - 5T]
