DRAM Burst Length
This setting allows you to set the size of Burst-Length for DRAM. Burst-
ing feature is a technique that DRAM itself predicts the address of the
next memory location to be accessed after the first address is accessed.
To use the feature, you need to define the burst length, which is the ac-
tual length of burst plus the starting address and allows internal address
counter to properly generate the next memory location. The bigger the
size, the faster the DRAM performance. Setting options: 4, 8.
DRAM Command Rate
This setting controls the DRAM command rate. Selecting 1T Command
allows DRAM signal controller to run at 1T (T=clock cycles) rate. Se-
lecting 2T Command makes DRAM signal controller run at 2T rate. 1T is
faster than 2T. Setting options: 1T Command, 2T Command.
AGP & P2P Bridge Control
Press <Enter> to enter the sub-menu and the following screen appears:
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 4M,
8M, 16M, 32M, 64M, 128M, and 256 M.
