Question:
What is the Graphic Window WR Combin in CMOS?
Answer:
In the CMOS setup often under the
AGP or Video section some users
will have an option Graphic Window WR Combin, with the
available options of Enable and Disable or may have a
video cache mode for
Uncacheable, Speculative Write-Combining (USWC) or Uncacheable (UC).
This setting enables the video card installed in your computer to
buffer information moving between the processor and the video memory
and send it as one write, instead of multiple small writes allowing
your video card to work more efficiently. If your video card
supports this mode you should Enable or set the video caching
to USWC otherwise this mode should be set to UC or
Disabled.
All recent video card will support this mode, if however you're
encountering crashes caused by your video card and this option is
available in your CMOS (BIOS)
setup you may also wish to consider disabling this feature. Users
can determine if the video card installed in the computer supports
this mode by consulting the video card documentation.
