BIOS Setup 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. 3-13
