FCC-B Radio Frequency Interference Statement
This equipment has been tested and found to comply with the limits
for a Class B digital device, pursuant to part 15 of the FCC rules. These
limits are designed to provide reasonable protection against harmful
interference in a residential installation. This equipment generates,
uses and radiates radio frequency energy, and, if not installed and
used in accordance with the instructions, may cause harmful interference to radio
communications. However, there is no guarantee that interference will not occur in a
particular installation. If this equipment does cause harmful interference to radio or
television reception, which can be determined by turning the equipment off and on, the
user is encouraged to try to correct the interference by one or more of the following
measures:
∙Reorient or relocate the receiving antenna.
∙Increase the separation between the equipment and receiver.
∙Connect the equipment into an outlet on a circuit different from that to which the
receiver is connected.
NOTE
∙The changes or modifications not expressly approved by the party responsible for
compliance could void the user’s authority to operate the equipment.
∙Shield interface cables and AC power cord, if any, must be used in order to comply
with the emission limits.
FCC Conditions
This device complies with part 15 of the FCC Rules. Operation is subject to the
following two conditions:
∙This device may not cause harmful interference.
∙This device must accept any interference received, including interference that may
cause undesired operation.
CE Conformity
Hereby, Micro-Star International CO., LTD declares that this device is in
compliance with the essential safety requirements and other relevant
provisions set out in the European Directive.
WEEE Statement
Under the European Union (“EU”) Directive on Waste Electrical and

Safety Information
∙The components included in this package are prone to damage from electrostatic
discharge (ESD). Please adhere to the following instructions to ensure successful
computer assembly.
∙Ensure that all components are securely connected. Loose connections may cause
the computer to not recognize a component or fail to start.
∙Hold the motherboard by the edges to avoid touching sensitive components.
∙It is recommended to wear an electrostatic discharge (ESD) wrist strap when
handling the motherboard to prevent electrostatic damage. If an ESD wrist strap
is not available, discharge yourself of static electricity by touching another metal
object before handling the motherboard.
∙Store the motherboard in an electrostatic shielding container or on an anti-static
pad whenever the motherboard is not installed.
∙Before turning on the computer, ensure that there are no loose screws or metal
components on the motherboard or anywhere within the computer case.
∙Do not boot the computer before installation is completed. This could cause
permanent damage to the components as well as injury to the user.
∙If you need help during any installation step, please consult a certified computer
technician.
∙Always turn off the power supply and unplug the power cord from the power outlet
before installing or removing any computer component.
∙Keep this user guide for future reference.
∙Keep this motherboard away from humidity.
∙Make sure that your electrical outlet provides the same voltage as is indicated on
the PSU, before connecting the PSU to the electrical outlet.
∙Place the power cord such a way that people can not step on it. Do not place
anything over the power cord.
∙All cautions and warnings on the motherboard should be noted.
∙If any of the following situations arises, get the motherboard checked by service
personnel:
• Liquid has penetrated into the computer.
• The motherboard has been exposed to moisture.
• The motherboard does not work well or you can not get it work according to user
guide.

⚠
Important
∙ Always unplug the power cord from the power outlet before installing or removing
the CPU.
∙ When installing a CPU, always remember to install a CPU heatsink. A CPU heatsink
is necessary to prevent overheating and maintain system stability.
∙ Confirm that the CPU heatsink has formed a tight seal with the CPU before booting
your system.
∙ Overheating can seriously damage the CPU and motherboard. Always make sure
the cooling fans work properly to protect the CPU from overheating. Be sure to
apply an even layer of thermal paste (or thermal tape) between the CPU and the
heatsink to enhance heat dissipation.
∙ Whenever the CPU is not installed, always protect the CPU socket pins by covering
the socket with the plastic cap.
∙ If you purchased a separate CPU and heatsink/ cooler, Please refer to the
documentation in the heatsink/ cooler package for more details about installation.

Introduction to the LGA1700 CPU
The surface of the LGA1700 CPU has four
notches and a golden triangle to assist in
correctly lining up the CPU for motherboard
placement. The golden triangle is the Pin 1
indicator.

∙ If only 1 DIMM is populated in a channel, then populate it in the DIMMA2 slot.
∙ Populate the same DIMM type in each channel, specifically: 1. Use the same DIMM
size; 2. Use the same number of ranks per DIMM.
∙ We don’t suggest other memory installation.
