BIOS Setup
Manual
If you want better performance for your system
other than the one “by SPD”, select “Manual” then
select the best option in the “CAS Latency Time”
and “Active to Precharge Delay fields.
3.1.3.2 CAS Latency Time
This field is used to select the local memory clock periods.
3.1.3.3 Active to Precharge Delay
The options are 5, 6 and 7.
3.1.3.4 DRAM RAS# to CAS# Delay
The options are 2 and 3.
3.1.3.5 DRAM RAS# Precharge
This field controls RAS# precharge (in local memory clocks).
3.1.3.6 Memory Frequency For
This field is used to select the memory clock speed of the DIMM.
3.1.3.7 System BIOS Cacheable
When this field is enabled, accesses to the system BIOS ROM
addressed at F0000H-FFFFFH are cached, provided that the cache
controller is enabled. The larger the range of the Cache RAM, the
higher the efficiency of the system.
3.1.3.8 Video BIOS Cacheable
As with caching the system BIOS, enabling the Video BIOS cache will
allow access to video BIOS addresssed at C0000H to C7FFFH to
be cached, if the cache controller is also enabled. The larger the range
of the Cache RAM, the faster the video performance.
