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
..
Connecting IDE and Floppy Cable
Connect 34-pin floppy cable and 40-pin IDE cable to floppy connector FDC and IDE
connector. The
blue connector
is IDE1 for clear identification. Be careful of the pin1
orientation. Wrong orientation may cause system damage.
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
flashing while the system is in suspend mode.
Connecting Front Panel Cable
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
