DRAM RAS# to CAS# Delay
This field allows you to insert a timing delay between the CAS and RAS strobe
signals, used when DRAM is written to, read from, or refreshed. Low value will
provide a faster performance; and high value made the system more stable. This
field applies only when synchronous DRAM is installed in the system.
The Choices: Auto (default), 2, 3, 4, 5, 6.
DRAM RAS# Precharge
If an insufficient number of cycles are allowed for RAS to accumulate its charge
before DRAM refresh, the refresh may be incomplete, and the DRAM may fail
to retain data. Low value will provide faster performance; and high value made
the system more stable. This field applies only when synchronous DRAM is
installed in the system.
The Choices: Auto (default), 2, 3, 4, 5, 6.
Precharge dealy (tRAS)
This item allows you to specify the minimum row active time (tRAS).
The Choices: Auto (default), 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15.
System Memory Frequency
This item allows you to select the Memory Frequency.
The Choices: Auto (default), 400MHz, 533MHz, and 667MHz.
On-Chip Frame Buffer Size
This item will be different as your memory modules. When the memory size is
decided, this frame buffer size will also be fixed.
The Choices: 8MB (default), 1MB.
UVMT Mode
This item allows you to select the UVMT mode.
The Choice: DVMT (default), FIXED, BOTH.
