Medix 1700SF User’s manual
25
This option allows you to insert a delay between the RAS (Row
Address Strobe) and CAS (Column Address Strobe) signals. This
delay occurs when the SDRAM is written to, read from or
refreshed. Reducing the delay improves the performance of the
SDRAM.
DRAM RAS# Precharge
This option sets the number of cycles required for the RAS to
accumulate its charge before the SDRAM refreshes. The default
setting for the Active to Precharge Delay is 4.
Precharge Delay (tRAS)
The default setting for the Precharge Delay is 12.
System Memory Frequency
The default setting is 533MHz.
SLP_S4# Assertion Width
The default setting is 1 to 2 Sec.
System BIOS Cacheable
The setting of Enabled allows caching of the system BIOS ROM at
F000h-FFFFFh, resulting in better system performance.
However, if any program writes to this memory area, a system
error may result.
Video BIOS Cacheable
The Setting Enabled allows caching of the video BIOS ROM at
C0000h-F7FFFh, resulting in better video performance.
However, if any program writes to this memory area, a system
error may result.
Memory Hole at 15M-16M
In order to improve performance, certain space in memory can be
reserved for ISA cards. This memory must be mapped into the
memory space below 16 MB. The choices are Enabled and
Disabled.
On-Chip VGA Setting
The fields under the On-Chip VGA Setting and their default
settings are:
PEG/On Chip VGA Control: Auto
On-Chip Frame Buffer Size: 8MB
