OS:
AMI BIOS
Supports “Plug and Play”
ACPI 1.1 compliance wake up events
SMBIOS 2.3.1 support
CPU frequency stepless control
(only for advanced users’ reference, see CAUTION 6)
Microsoft® Windows® 98SE / ME / 2000 / XP compliant
CAUTION!
1. For power-saving sake, it is strongly recommended to enable AMD’s Cool ‘n’
QuietTM technology under Windows system. See APPENDIX on page 37 of
“User Manual” in the Support CD to enable AMD’s Cool ‘n’ QuietTM technology.
2. While CPU overheat is detected, the system will automatically shutdown.
Before you resume the system, please check if the CPU fan on the
motherboard functions properly and unplug the power cord, then plug it
back again. To improve heat dissipation, remember to spray thermal
grease between the CPU and the heatsink when you install the PC system.
3. Do NOT use a 3.3V AGP card on the AGP slot of this motherboard!
It may cause permanent damage!
4. Power Management for USB 2.0 works fine under Microsoft® Windows® XP
SP1 / 2000 SP4. It may not work properly under Microsoft® Windows® 98 /
ME.
5. For microphone input, this motherboard supports mono modes. For audio
output, this motherboard supports 2-channel, 4-channel, 6-channel, and 8-
channel modes. Please check the table on page 3 for proper connection.
6. Although this motherboard offers stepless control, it is not recommended
to perform over-clocking. Frequencies other than the recommended CPU
FSB frequencies may cause the instability of the system or damage the
CPU.

Pre-installation Precautions
Take note of the following precautions before you install mother-
board components or change any motherboard settings.
1.
2.
Unplug the power cord from the wall socket before touching any
component. Failure to do so may cause severe damage to the
motherboard, peripherals, and/or components.
To avoid damaging the motherboard components due to static
electricity, NEVER place your motherboard directly on the car-
pet or the like. Also remember to use a grounded wrist strap or
touch a safety grounded object before you handle components.
Hold components by the edges and do not touch the ICs.
3.
4. Whenever you uninstall any component, place it on a
grounded antstatic pad or in the bag that comes with the
component.
5. When placing screws into the screw holes to secure the
motherboard to the chassis, please do not over-tighten the
screws! Doing so may damage the motherboard.

Step 1. Unlock the socket by lifting the lever up to a 90° angle.
Step 2. Position the CPU directly above the socket such that its marked corner
matches the base of the socket lever.
Step 3. Carefully insert the CPU into the socket until it fits in place.
The CPU fits only in one correct orientation. DO NOT force the CPU
into the socket to avoid bending of the pins.
Step 4. When the CPU is in place, press it firmly on the socket while you push
down the socket lever to secure the CPU. The lever clicks on the side tab
to indicate that it is locked.
Install CPU fan and heatsink. For proper installation, please kindly refer to
the instruction manuals of your CPU fan and heatsink vendors.

2.2 Installation of Memory Modules (DIMM)
939A8X-M motherboard provides four 184-pin DDR (Double Data Rate) DIMM slots,
and supports Dual Channel Memory Technology. For dual channel configuration, you
always need to install identical (the same brand, speed, size and chip-type) DDR
DIMM pair in the slots of the same color. In other words, you have to install identical
DDR DIMM pair in Dual Channel A (DDR1 and DDR2; Blue slots; see p.2 No. 6) or
identical DDR DIMM pair in Dual Channel B (DDR3 and DDR4; Black slots; see p.2
No. 7), so that Dual Channel Memory Technology can be activated. This motherboard
also allows you to install four DDR DIMMs for dual channel configuration, and please
install identical DDR DIMMs in all four slots. You may refer to the Dual Channel
Memory Configuration Table below.

* For the configuration (3), please install identical DDR DIMMs in all four slots.
* It is recommended to install DDR3 and DDR4 (black slots) first. Then to install
in DDR1 and DDR2. (That is, to populate DDR DIMM from the far side of CPU
towards to the near side of CPU.)
1.
2.
3.
If you want to install two different memory modules, for optimal
compatibility and reliability, it is recommended to install them in the
slots of different color. In other words, install them either in DDR1
and DDR3.
If only one memory module or three memory modules are installed
in the DDR DIMM slots on this motherboard, it is unable to activate
the Dual Channel Memory Technology.
If a pair of memory modules is NOT installed in the same Dual
Channel, for example, installing a pair of memory modules in DDR1
and DDR3, it is unable to activate the Dual Channel Memory Tech-
nology .
