RAS# to CAS# delay (Tr c d )
When DRAM is refreshed, both rows and columns are addressed separately.
This setup item allows you to determine the timing of the transition from RAS
(row address strobe) to CAS (column address strobe). The less the clock cycles,
the faster the DRAM performance. The available setting values are: Auto, 2 - 7.
Row Precharge Time (Tr p )
This item controls the number of cycles for Row Address Strobe (RAS) to be
allowed to precharge. If insufficient time is allowed for the RAS to accumulate
its charge before DRAM refresh, refreshing may be incomplete and DRAM may
fail to retain data. This item applies only when synchronous DRAM is installed
in the system. The available setting values are: Auto, 2 - 6.
This feature is especially designed for AMD Athlon processor, which provides
a CPU temperature detecting function to prevent your CPU from overheating
due to the heavy working loading. The available setting values are: Disabled,
Auto.
