MA 1T/2T Select
This setting controls the SDRAM command rate. Selecting Auto allows
SDRAM signal controller to run at 1T (T=clock cycles) rate. Selecting
MA 1T makes SDRAM signal controller run at 2T rate. 1T is faster than
2T. Setting options: Auto, 2T, 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
256MB.
AGP Fast Write
This option enables or disables the AGP Fast Write feature. The Fast Write
technology allows the CPU to write directly to the graphics card without passing
anything through the system memory and improves the AGP 4X speed.
