"
Input Delay Value:
This item allows you to adjust the data input strobe delay time of memory. You can key in the HEX
number into this section. The minimum number is 0000, and maximum number is 003F.
DDR DQS Output Delay:
Two options are available: Auto or Manual. The default setting is
Auto
. If you set to
Manual
, then the
next item will be available.
"
Output Delay Value:
This item allows you to adjust the data output strobe delay time of memory. You can key in the HEX
number into this section. The minimum number is 0000, and maximum number is 00FF.
Command Drive Strength:
Two options are available: Lo or Hi. The default setting is
Lo
. This item can adjust the drive strength for
command sent to DDR SDRAM. This will depend on your DDR SDRAM specification and numbers to
set. More DDR SDRAM DIMM installed, you may set it to
Hi
.
DRAM Queue Depth:
Three options are available: 2 Level
)
3 Level
)
4 level. The default setting is
4 Level
. This item sets
DRAM queue depth to accommodate maximum memory throughput.
DRAM Command Rate:
Two options are available: 2T Command or 1T Command. The default setting is
2T Command
. When the
host (northbridge) locates the desired memory address, it then processes the wait state of commands. Set
it to
2T Command
for system compatibility or to
1T Command
for system performance.
DCLK Feedback Delay:
Nine options are available: Auto
)
0 ps
)
120 ps
)
240 ps
)
360 ps
)
480 ps
)
600 ps
)
720 ps
)
840 ps. The default setting is
0
. The northbridge via DCLK feedback signal to sense the DRAM clock
timing of DRAM module. This item will effect the DRAM module’s stability, we suggestion you set to
0
.
