G965 Micro 775 DRAM RAS# to CAS# Dela y This field allows you to insert a timing delay between the CAS and RAS strobe signals, used when DRAM is written to, read from, or refreshed. Low value will provide a fast er performance; and high value made the system more stable. This fi eld applies only when synchronous DRAM is installed in the system. The Choices: Auto (default),3, 4, 5, 6, 7. DRAM RAS# Precharge If an insuffi cient number of cycles are allowed for RAS to accumulate its charge before DRAM refresh, the refresh may be incomplete, and the DRAM may fail to retain data. Low value will provide faster performance; and high value made the system more stable. This field applies only when synchronous DRAM is installed in the system. The Choices: Auto (default),3, 4, 5, 6, 7. Precharge dealy (tRAS) This item allows you to specify the minimum row active time (tRAS). The Choices: Auto (default),9, 10,11,12,13,14,15,16,17,18,19,20,21,22,23. TWR The Choices: Auto (default),3,4,5,6,7,8,9, 10,11,12,13,14,15. TWTR The Choices: Auto (default),2,3,4,5,6,7,8,9, 10,11,12,13,14,15. TRRD This field specifies the RAS# to CAS# Delay to read/ write command to the same bank. Typically -20 Nsec. The Choices: Auto (default),2,3,4,5,6,7,8,9, 10,11,12,13,14,15. TRTP The Choices: Auto (default),2,3,4,5,6,7,8,9, 10,11,12,13,14,15. 36
