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 that are
less than 18 chips.

right direction.
Attach the power LED, Keylock, speaker, and reset
switch connectors to the corresponding pins. If you
enable "Suspend Mode" item in BIOS Setup, the
ACPI & Power LED will keep flashing while the
system is in suspend 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.
