Safety information
Electrical safety
To prevent electrical shock hazard, disconnect the power cable from the electrical outlet
•
before relocating the system.
When adding or removing devices to or from the system, ensure that the power cables
•
for the devices are unplugged before the signal cables are connected. If possible,
disconnect all power cables from the existing system before you add a device.
Before connecting or removing signal cables from the motherboard, ensure that all
•
power cables are unplugged.
Seek professional assistance before using an adapter or extension cord. These devices
•
could interrupt the grounding circuit.
Ensure that your power supply is set to the correct voltage in your area. If you are not
•
sure about the voltage of the electrical outlet you are using, contact your local power
company.
If the power supply is broken, do not try to x it by yourself. Contact a qualied service
•
technician or your retailer.

1.2 Motherboard overview
1.2.1 Before you proceed
Take note of the following precautions before you install motherboard components or change
any motherboard settings.
• Unplug the power cord from the wall socket before touching any component.
• Before handling components, use a grounded wrist strap or touch a safely grounded
object or a metal object, such as the power supply case, to avoid damaging them due
to static electricity.
• Hold components by the edges to avoid touching the ICs on them.
• Whenever you uninstall any component, place it on a grounded antistatic pad or in the
bag that came with the component.
• Before you install or remove any component, ensure that the ATX power supply is
switched off or the power cord is detached from the power supply. Failure to do so
may cause severe damage to the motherboard, peripherals, or components.

1.2.3 Central Processing Unit (CPU)
The motherboard comes with a surface mount LGA1150 socket designed for the 4th
Generation Intel® Core™ i7 / Intel® Core™ i5 / Intel® Core™ i3, Pentium®, and Celeron®
processors.
• Ensure that all power cables are unplugged before installing the CPU.
• Ensure that you install the correct CPU designed for LGA1150 only. DO NOT install a
CPU designed for LGA1155 and LGA1156 sockets on the LGA1150 socket.
• Upon purchase of the motherboard, ensure that the PnP cap is on the socket and
the socket contacts are not bent. Contact your retailer immediately if the PnP cap
is missing, or if you see any damage to the PnP cap/socket contacts/motherboard
components. ASUS will shoulder the cost of repair only if the damage is shipment/
transit-related.
• Keep the cap after installing the motherboard. ASUS will process Return Merchandise
Authorization (RMA) requests only if the motherboard comes with the cap on the
LGA1150 socket.
• The product warranty does not cover damage to the socket contacts resulting from
incorrect CPU installation/removal, or misplacement/loss/incorrect removal of the PnP
cap.

1.2.4 System memory
The motherboard comes with two Double Data Rate 3 (DDR3) Dual Inline Memory Modules
(DIMM) slots.
A DDR3 module is notched differently from a DDR or DDR2 module. DO NOT install a DDR
or DDR2 memory module to the DDR3 slot.
Recommended memory congurations
ASUS MAXIMUS VI IMPACT
Chapter 1
1-9
Memory congurations
You may install 1GB, 2GB, 4GB and 8GB unbuffered and non-ECC DDR3 DIMMs into the
DIMM sockets.
• Memory module with memory frequency higher than 2133 MHz and its corresponding
timing or the loaded XMP prole is not the JEDEC memory standard. The stability and
compatibility of these memory modules depend on the CPU’s capabilities and other
installed devices.
• You may install varying memory sizes in Channel A and Channel B. The system maps
the total size of the lower-sized channel for the dual-channel conguration. Any excess
memory from the higher-sized channel is then mapped for single-channel operation.
• According to Intel CPU spec, DIMM voltage below 1.65V is recommended to protect
the CPU.
• Always install DIMMs with the same CAS latency. For optimal compatibility, we
recommend that you install memory modules of the same version or date code (D/C)
from the same vendor. Check with the retailer to get the correct memory modules.
• Due to the memory address limitation on 32-bit Windows OS, when you install 4GB
or more memory on the motherboard, the actual usable memory for the OS can be
about 3GB or less. For effective use of memory, we recommend that you do any of the
following:
a) Use a maximum of 3GB system memory if you are using a 32-bit Windows OS.
b) Install a 64-bit Windows OS when you want to install 4GB or more on the
motherboard.
c) For more details, refer to the Microsoft
com/kb/929605/en-us.
• This motherboard does not support DIMMs made up of 512Mb (64MB) chips or less
(Memory chip capacity counts in Megabit, 8 Megabit/Mb = 1 Megabyte/MB).

support site at http://support.microsoft.
Chapter 1

• The default memory operation frequency is dependent on its Serial Presence Detect
(SPD), which is the standard way of accessing information from a memory module.
Under the default state, some memory modules for overclocking may operate at a
lower frequency than the vendor-marked value. To operate at the vendor-marked or at
a higher frequency, refer to section 3.4 Extreme Tweaker menu for manual memory
frequency adjustment.
• For system stability, use a more efcient memory cooling system to support a full
memory load (2 DIMMs) or overclocking condition.
