SDRAM RAS to CAS Delay
This controls the latency between the SDRAM active command and the
read/write command.
SDRAM RAS Precharge Time
This controls the idle clocks after issuing a precharge command to the
SDRAM.
SDRAM Cycle Time (Tras, Trc) [7T, 9T]
This feature controls the number of SDRAM clocks used for SDRAM pa-
rameters Tras and Trc. Tras specifies the minimum clocks required between
active command and precharge command. Trc specifies the minimum clocks
required between active command and re-active command. Configuration
options: [5T, 7T] [7T, 9T]
SDRAM Page Closing Policy [One Bank]
This feature controls that after a page miss whether the Graphics and Memory
Controller Hub (GMCH) will issue "precharge only the bank" or "precharge
all" command to a specific opened SDRAM bank. Configuration options:
[One Bank] [All Banks]
CPU Latency Timer [Enabled]
This controls the GMCH's response to CPU deferrable cycles. Configura-
tion options: [Disabled] [Enabled]
Command Per Cycle [Enabled]
When onboard VGA is used, CPU can help to gain graphics performance by
increasing proper SDRAM cycles combinations. Configuration options: [En-
abled] [Disabled]
Graphics Window Size [64MB]
This feature allows you to select the size of mapped memory for AGP graphic
data. Configuration options: [64MB] [32MB]
AGP Capability [4X Mode]
This motherboard supports the AGP 4x interface, which transfers video data
at 1066MB/s. Since AGP 4x is backward-compatible, you may leave the
default [4X Mode] on no matter you are using an AGP 2x video card. When
set to [2X Mode], the AGP interface will only provide a peak data through-
put of 533MB/s even if you are using an AGP 4x card. Configuration op-
tions: [2X Mode] [4X Mode]
