Tip: The driving capability of new generation
chipset is limited due to the lack of a memory
buffer (to improve performance). This makes
DRAM chip count an important factor to take
into consideration when you install DIMMs.
Unfortunately, there is no way that the BIOS
can identify the correct chip count, you need to
calculate the chip count by yourself. The
simple rule is: By visual inspection, use only
DIMMs which are less than 16 chips.

Attach the power LED, speaker, and reset
switch connectors to the corresponding pins.
If you enable "Suspend Mode" item in BIOS
Setup, the ACPI & Power LED will keep

mode.
Locate the power switch cable from your
ATX housing. It is 2-pin female connector
from the housing front panel. Plug this
connector to the soft-power switch
connector marked SPWR.
