Advanced Dram Control - JETWAY 603TCR4A User Manual

3-6-1 Advanced DRAM Control

The "Advanced DRAM Control" includes settings for the chipset dependents features.
These features are related to system performance. Make sure you fully understand the
items contained in this menu before you try to change anything. You may change the
parameter settings to improve system performance. However, it may cause your
system to be unstable if the setting is not correct for your system configuration.

Precharge Command
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 date. Fast
gives faster performance; and Slow gives more stable performance. This field applies only
when synchronous DRAM is installed in the system. The settings are: 2 and 3.
Active Command
This field let's 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. The settings are: 2 and 3.
Active to CMD Command
Select the number of SCLKs for an access cycle. The settings are: 5/7 and 6/8.
SDRAM Cycle Length
When synchronous DRAM is installed, the number of clock cycles of CAS latency depends
on the DRAM timing. The settings are: 2 and 3.
