BIOS Setup Bank Interleave This item is for setting 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 is for setting 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, 3T, 4T, 5T] Active to Precharge (Tras) This field is for setting 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: [05T, 06~20T] Active to CMD (Trcd) This field is only available when "DRAM Timing" is set to "Manual". Settings: [2T, 3T, 4T, 5T] REF to ACT / REF (Trfc) This field is only available when "DRAM Timing" is set to "Manual". Settings: [08T, 09~71T] 55
