MA 1T/2T Select
This setting controls the SDRAM command rate. Setting to Auto allows the SDRAM
command rate to be determined by the BIOS. Selecting MA 1T/MA 2T makes
SDRAM signal controller run at 1T/2T rate. 1T is faster than 2T. Setting options:
Auto, MA 2T, MA 1T.
AGP Aperture Size
This setting controls just how much system RAM can be allocated to AGP for
video purposes. The aperture is a portion of the PCI memory address range
dedicated to graphics memory address space. Host cycles that hit the aperture
range are forwarded to the AGP without any translation. The option allows the
selection of an aperture size of
4MB, 8MB, 16MB, 32MB, 64MB, 128MB, and
256 MB.

ogy allows CPU to write directly into the graphics controller without passing
anything through system memory and improves 8x speed accordingly. Select
