MS-7325 Mainboard
Min RAS# Active Time (TRAS)
When the MCT Timing Mode sets to [Manual], the field is adjustable. This
setting determines the time RAS takes to read from and write to a memory cell.
RAS# Precharge Time (TRP)
When the MCT Timing Mode sets to [Manual], the field is adjustable. This item
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, refreshing may be incomplete and DRAM may fail to retain
data. This item applies only when synchronous DRAM is installed in the system.
RAS# to CAS# Delay (TRCD)
When the MCT Timing Mode sets to [Manual], the field is adjustable. When
DRAM is refreshed, both rows and columns are addressed separately. This
setup item allows you to determine the timing of the transition from RAS (row
address strobe) to CAS (column address strobe). The less the clock cycles, the
faster the DRAM performance.
ROW to ROW Delay (TRRD)
When the MCT Timing Mode sets to [Manual], the field is adjustable. Specifies
the active-to-active delay of different banks.
ROW Cycle Time (TRC)
When the MCT Timing Mode sets to [Manual], the field is adjustable. The row
cycle time determines the minimum number of clock cycles a memory row takes
to complete a full cycle, from row activation up to the precharging of the active
row.
Bank Interleaveing
This field selects 2-bank or 4-bank interleave for the installed SDRAM. Disable
the function if 16MB SDRAM is installed.
Enable Clock to All DIMMs
Enable unused clocks to all DIMMs even memory DIMMs are not populated.
1T/2T Timing Mode
This field controls the SDRAM command rate. Selecting [1T] makes SDRAM
signal controller to run at 1T (T=clock cycles) rate. Selecting [2T] makes SDRAM
signal controller run at 2T rate.
SoftWare Memory hole
Enable Memory Remapping Around Memory Hole.
Adjust Chipset Voltage
Allows to adjust the chipset voltage.
