DRAM RAS# to CAS# Delay This field lets you insert a timing delay between the CAS and RAS strobe signals, used when DRAM is written to, read from, or refreshed, Fast gives faster performance; and Slow gives more stable performance. This field applies only when synchronous DRAM is installed in the system. 2,3,4,5,6,Auto DRAM RAS# Precharge TIme If an insufficient number of cycles is allowed for the RAS to accumulate its charge before DRAM refresh, the refresh may be incomplete and the DRAM may fail to retain data. Fast fives faster performance; and Slow gives more stable performance.This field applies only when synchronous DRAM is installed in the syste. 2,3,4,5,6,Auto Active Precharge Delay This option is used to set up the timing delay between the 4,5,6,7,8,9,10,11, SDRAM active to precharge. 12,Auto Refresh Mode Select This option is used to set up e the Refresh Mode 7.8us 15.6us Auto DVMT Mode This option is used to select the video mode.
