Setting BIOS Function
transition from RAS (row address strobe) to CAS (column address strobe).
The less the clock cycles, the faster the DRAM performance. Settings:
[2T] to [5T].
TRP
This setting controls the number of cycles for Row Address Strobe (RAS)
to be allowed to precharge. If insufficient time is allowed for the RAS to
accumulate its charge before DRAM refresh, refresh may be incomplete
and DRAM may fail to retain data. This item applies only when synchro-
nous DRAM is installed in the system. Setting options: [2T] to [5T].
TRAS
This setting determines the time RAS takes to read from and write to a
memory cell. Setting options: [4T] to [9T].
Dual channel Interleave
Setting options: [system optional] and [graphics optional].
AGP Aperture Size (MB)
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 [32MB],
[64MB], [128MB], [256MB], [512MB], [1GB], and [2GB].
Onboard VGA Frame Buffer
Frame Buffer is the video memory that stores data for video display
(frame). This field is used to determine the memory size for Frame
Buffer. Larger frame buffer size increases video performance. Settings:
[8M], [16M], [32M], [64MB], [128MB].
