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 qualied service

technician or your retailer.

processors in the LGA1155 package, with iGPU, memory, and PCI Express controllers
integrated to support onboard graphics out with dedicated chipsets, 2-channel (4 DIMMs)
DDR3 memory, and 16 PCI Express 3.0/2.0 lanes. This provides great graphics performance.
Intel® 3rd/2nd generation Core™ i7/i5/i3/Pentium®/Celeron® processors are among the most

powerful and energy efcient CPUs in the world.

Intel® Z77 Express Chipset

The Intel® Z77 Express Chipset is a single-chipset designed to support the 1155 socket Intel®
3rd/2nd generation Core™ i7/i5/ i3/Pentium®/Celeron® processors. It provides improved

performance by utilizing serial point-to-point links, allowing increased bandwidth and stability.

Additionally, Z77 chipset provides 4 USB 3.0 ports for 10 times faster data retrieval speed.
Moreover, Intel® Z77 Express Chipset can also enable iGPU function, letting users enjoy the

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.

Ensure that all power cables are unplugged before installing the CPU.

• The LGA1156 CPU is incompatible with the LGA1155 socket. DO NOT install a

LGA1156 CPU on the LGA1155 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

LGA1155 socket.

• 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 conguration. Any excess
memory from the higher-sized channel is then mapped for single-channel operation.

• Due to Intel
MHz memory module will run at DDR3 2133/1866/1600 MHz frequency as default.

• 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 optimum compatibility, we

recommend that you obtain memory modules from the same vendor.

• 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:

- Use a maximum of 3GB system memory if you are using a 32-bit Windows OS.

- Install a 64-bit Windows OS when you want to install 4GB or more on the

• 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
frequency adjustment.

• For system stability, use a more efcient memory cooling system to support a full

memory load (4 DIMMs) or overclocking condition.
