4.7 Advanced Chipset Features
This section contains completely optimized chipset’s features on the
board that you are strongly recommended to leave all items on this
page at their default values unless you are very familiar with the
technical specifications of your system hardware.
z DRAM Timing Selectable
Use this item to increase the timing of the memory. This is related
to the cooling of memory.
z CAS Latency Time
You can select CAS latency time in HCLKs 2, 3, or Auto. The
board designer should set the values in this field, depending on
the DRAM installed. Do not change the values in this field unless
you change specifications of the installed DRAM or the installed
CPU.
z System BIOS Cacheable
Selecting Enabled allows caching of the system BIOS ROM at
F0000h-FFFFFh, resulting in better system performance. However,
if any program writes to this memory area, a system error may
result. The default value is “Disabled”.
z Video BIOS Cacheable
This item allows you to change the Video BIOS location from ROM
to RAM. Video Shadow will increase the video speed.
