7. Install DIMM Modules
6. JP23 FSB/PCI Clock Ratio
8. Connecting IDE & Floppy Cables
9. Connecting Front Panel Cable
This jumper is used to specify the relationship of PCI and FSB clock. Generally
speaking, if you are not overclockers, we recommend you to set at the default setting.
This motherboard has three 168-pin DIMM sockets that allow you to install PC100 or
PC133 memory up to 512MB. The AX3SP/AX3SP Pro supports non-ECC/ECC and
Registered SDRAM.
Connect 34-pin floppy cable and 40-pin IDE cable to floppy connector FDC and IDE
connector. Be careful of the pin1 orientation. Wrong orientation may cause system
damage.
Warning:
High CPU core voltage
may be able to increase CPU
speed for overclocking, but you
may damage the CPU or reduce
the CPU lifecycle.

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
.
Note:
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
