DRAM Clock
Default: Host CLK
This item sets the DRAM Clock. We recommend that you leave this
item at the default value.
Memory Hole
Default: Disabled
This item can be used to reserve memory space for some ISA expan-
sion cards that require it.
Read Around Write
Default Disabled
This item optimizes DRAM. If a memory read is addressed to a location
whose latest write is being held in a buffer before being written to mem-
ory, the read is satisfied through the buffer contents, and the read is not
sent to the DRAM.
Concurrent PCI/Host
Default: Disabled
When disabled, the CPU bus is occupied during the entire PCI opera-
tion period.
Fast R-W Turn Around
Default: Disabled
When this is enabled, the chipset will insert one extra clock to the turn-
around of back-to-back DRAM cycles.
System BIOS Cacheable
Default: Enabled
Video RAM Cacheable
Default: Enabled
These items allow the video and/or system to be cached in memory for
faster execution. We recommend that you leave these items at the de-
fault value.
AGP Aperture Size
Default: 64 MB
This item defines the size of the aperture if you use an AGP graphics
adapter. It refers to a section of the PCI memory address range used
for graphics memory. We recommend that you leave this item at the
default value.
AGP-2X Mode
Default: Enabled
This item allows you to enable or disable the caching of display data for
the video memory of the processor. Enabling AGP-2X Mode can greatly
improve the display speed. If your graphics display card does not sup-
port this feature, you need to disable this item.
