giving you an edge in overclocking your system. So, if you hit a snag
while overclocking, try increasing the CAS latency time.
DRAM RAS# to CAS# Delay
This item allows you to select a delay time between the CAS and RAS
strobe signals. It only applies when DRAM is written to, read from, or
refreshed. This field is adjustable only when “DRAM Timing Selectable”
is set to “manual”. This field is locked when “DRAM Timing Selectable”
is set to “By SPD” and is automatically determined by the system.

System BIOS Cacheable
Enabling this function allows caching of the system BIOS ROM at
F0000h-FFFFFh, which results in better system performance. However, if
any program writes to this memory area, a system error may result. It is
advisable to leave it in default setting. Caching the system BIOS results in
better performance than shadowing the system BIOS.
Video BIOS Cacheable
Select “ Enabled ” to allow caching of the video BIOS which may
improve performance. If any other program writes to this memory area, a
system error may result.
Options: Enabled, Disabled (default)
