Для уменьшения износа твердотельного диска все же рекомендуем использовать второй диск в системе, и именно HDD. Так будет надежней и с точки зрения безопасного хранения личных файлов, т.к. в случае системного сбоя придется форматировать весь SSD без возможности восстановления с него данных.

Если в материнской плате ноутбука имеется M.2, то он обычно свободен. Но для ноутбуков обычно используют формфактор M.2 с индексом 2242 или 2260, где последние две цифры — длина модуля в мм.

ASUS Anti-Surge Protection

This special design prevents expensive devices and the motherboard from damage caused
by power surges from switching power supply (PSU).

C.P.R. (CPU Parameter Recall)

The BIOS C.P.R. feature automatically restores CPU default settings when the system
crashes due to overclocking failure. C.P.R. eliminates the need to open the system
chassis and clear the RTC data. Simply shut down and reboot the system, and the BIOS
automatically restores the CPU parameters to their default settings.

ErP ready

This motherboard is European Union´s Energy-related Products (ErP) ready, and ErP

requires products to meet certain energy efciency requirements with regard to energy

consumption. This is in line with ASUS’ vision of creating environment-friendly and energy-

efcient products through product design and innovation aimed at reducing carbon footprint

and mitigating environmental impact.

1.2 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.

1.3 Motherboard overview

Before you install the motherboard, study the conguration of your chassis to ensure that the
motherboard ts.

Unplug the power cord before installing or removing the motherboard. Failure to do so can
cause you physical injury and damage to motherboard components.

1.3.1 Placement direction

When installing the motherboard, place it into the chassis in the correct orientation. The edge
with external ports goes to the rear part of the chassis as indicated in the image.

1.3.2 Screw holes

Place six screws into the holes indicated by circles to secure the motherboard to the chassis.

Do not overtighten the screws! Doing so can damage the motherboard.

Place this side

towards the rear

of the chassis

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.

• 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.

1.5 System memory

1.5.1 Overview

This motherboard comes with two Double Data Rate 3 (DDR3) Dual Inline Memory Module
(DIMM) sockets. A DDR3 module has the same physical dimensions as a DDR2 DIMM but
is notched differently to prevent installation on a DDR2 DIMM socket. DDR3 modules are

developed for better performance with less power consumption. The gure illustrates the

location of the DDR3 DIMM sockets:

1.5.2 Memory congurations

You may install 1GB, 2GB, 4GB, and 8GB unbuffered non-ECC DDR3 DIMMs into the DIMM
sockets.

• 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.

• 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
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

— Install a 64-bit Windows

®

OS if you want to install 4GB or more on the

motherboard.

• This motherboard does not support DIMMs made up of 512 megabits (Mb) chips or
less.

• Memory modules with memory frequency higher than 2133 MHz and its corresponding
timing or the loaded X.M.P. Prole is not the JEDEC memory standard. The stability

and compatibility of these memory modules depend on the CPU’s capabilities and
other installed devices.

• The maximum 16GB memory capacity can be supported with 8GB or above DIMMs.
ASUS will update the memory QVL once the DIMMs are available in the market.

• 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 2.4 Ai Tweaker menu for manual memory
frequency adjustment.

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

memory load (2 DIMMs) or overclocking condition.
