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 LGA2011 socket designed for the 2nd
Generation Intel® Core™ i7 processor family.
• Ensure that all power cables are unplugged before installing the CPU.
• 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
LGA2011 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 eight 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
Chapter 1
1-10
Chapter 1: Product introduction
Memory congurations
You may install 2GB, 4GB and 8GB unbuffered and non-ECC DDR3 DIMMs into the DIMM
sockets.
• You may install varying memory sizes in Channel A, Channel B, Channel C, and
Channel D. The system maps the total size of the lower-sized channel for the dualchannel conguration. Any excess memory from the higher-sized channel is then
mapped for single-channel operation.
• According to Intel
the CPU.
• Due to CPU behavior, DDR3 2200/2000/1800 MHz memory modules run at DDR3
2133/1866/1600 MHz frequency as default.
• Always install DIMMs with the same CAS latency. For optimum compatibility, we
recommend that you obtain memory modules from the same vendor.
• Due to the memory address limitation on 32-bit Windows
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
b) Install a 64-bit Windows
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).

• 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 3.5 Ai Tweaker menu for manual memory
frequency adjustment.
• For system stability, use a more efcient memory cooling system to support a full
memory load (8 DIMMs) or overclocking condition.
• Memory modules with memory frequency higher than 2133MHz and their
corresponding timing or the loaded XMP prole is not the JEDEC memory standard.
The stability and compatibility of the memory modules depend on the CPU’s
capabilities and other installed devices.
• Always install the DIMMS with the same CAS Latency. For an optimum compatibility,
we recommend that you install memory modules of the same version or data code (D/
C) from the same vendor. Check with the vendor to get the correct memory modules.
