In the front side besides company name, name of chipset, type of CPU supported and device model you’ll find the conformity to concept 5X PROTECTION which includes:

  • Special safety devices for increased protection against over current and short circuit.
  • Protection against electrostatic discharges.
  • Japanese solid capacitors with increased service life (up to 5000 hours at 105°C).
  • Improved design of interface panel made of stainless steel coated with chromium oxide. It has high oxidation resistance which makes it three times more wear-resistant.
  • Digital PWM controllers for control of CPU power and memory modules that are used in accordance with the original concept of DIGI + VRM.


The reverse side traditionally has the diagrammatic representation of the motherboard, a brief list of its technical characteristics, as well as the key features and advantages of the products:

  • USB 3.0 Boost – the support of UASP protocol is used to speed up the operation of USB 3.0 interface.
  • Fan Xpert - intelligence fan control system used for effective cooling with minimal noise level.
  • AI Suite III – together with motherboard there is proprietary software used for fine-tuning of several parameters settings without entering the BIOS.
  • Network iControl - using the bundled software you can control network activity in real time and set each program priority to network resources access.

Also there is a support of AMD Eyefinity and AMD Dual Graphics technologies, as well as the presence of HDMI video output on the interface panel which has the ability to display images in a resolution of 3840 x 2160 pixels (4K Ultra HD).


In the box you’ll find the most necessary accessories. Scope of supply includes:

• driver disk;

• user's manual;

• two SATA-cables;

• faceplate of interface panel

Design and features   


Model ASUS A88XM- PLUS is pefrormed on microATX dark brown printed circuit board (236 x 234 mm). Dark colors of the board and ports are completed with bright yellow elements. This is ASUS corporate identity.

The packaging of the elements is pretty good but there are some peculiarities. First of all this is a unique arrangement of TPM socket over expansion slots. Secondly, the leading-in socket of remote panel with USB 3.0 ports were shifted from right side to bottom part and this fact may cause the inconvenience for cabling. Also here you’ll not find the holes for fastening screws on the right side. So we don’t recommend to make much efforts during connection of 24-pin ATX socket, RAM modules and three SATA-interfaces.  


On the reverse side of the product you will see the standard support plate of the CPU socket and plastic fastening clips of a single radiator which is responsible for chipset cooling.

 ASUS A88XM-PLUS At the bottom of the board there are the following connectors: front panel audio leading-in sockets, S/PDIF out, COM and LPT ports, as well as front panel leading-in socket. Also here are: four USB leading-in sockets: three for USB 2.0 and one for USB 3.0. Total number of USB 2.0 sockets is ten: (six internal and four on the interface panel) as well as four USB 3.0 sockets (two internal and two external). All connectors function is provided by the chipset AMD A88X. ASUS A88XM-PLUS 

The possibility of disk subsystem organization is performed by eight SATA 6 GB/s ports. All of them operate due to chipset. Here is the support of SATA RAID 0, RAID 1, RAID 5, RAID 10 and JBOD arrays. As it can be seen a portion of SATA sockets is parallel to board surface and another portion has perpendicular direction. As a result even the longest expansion boards won’t embarrass the connection of drives. But due to the absence of fastening screws on the right side you should be careful during the usage of three perpendicular ports.

ASUS A88XM-PLUS ASUS A88XM- PLUS motherboard is equipped with four DIMM-slots for memory modules of DDR3 standard which are equipped with latches on both sides. RAM can operate in dual channel mode. For its implementation modules should be installed either into first and third or second and fourth slots. Memory boards operating at frequencies up to 2133 MHz in the nominal mode and up to 2400 MHz while overclocking are supported. Despite the specified by manufacture support of 64GB memory the actual maximum index was 32GB. This should be enough for almost all tasks.

In addition we want to pay your attention to MemOK! Button. It is a button used to adjust settings of RAM to enable system operation. Also here is GPU Boost switch used for overclocking the graphics core.



Cooling system of the product consists of two aluminum radiator. The first provides heat removal out of AMD A88X circuit, while the second covers the elements of power subsystem.

In the process of testing the following temperature indices were fixed:

• radiator for chipset cooling - 46,5°°C;

• radiator for cooling of processor elements power - 45,7°C.

Despite elevated temperature of radiator on the chipset, the received results are characterized as good.



Processor power supply is performed via 2+4 phase scheme for computational cores and additional joints. Converter is based on a digital PWM controller ASP1106 with integrated DIGI+VRM power consumption subsystem control. All power components of CPU have high reliability level: solid Japanese capacitors and chokes with ferrite core are used. Basic 24-pin and additional 4-pin connectors are use for power feeding.    

ASUS A88XM-PLUS To extend motherboard functionality the user has 4 slots:

  1. PCI Express 3.0 x16 (in mode х16);
  2. PCI Express 2.0 x1;
  3. PCI;
  4. PCI Express 2.0 x16 (in mode х4);

Even taking into consideration the support of AMD CrossFireX technology, this configuration is suitable only for one graphics card. In case of two graphics adapters connection the lines between them are divided according х16+х4 scheme. Also there is a support of AMD Dual Graphics technology with allows to operation together with integrated graphics core.

In such a way the second PCI Exrepss x16 socket should be used for the connection of any expansion board taking into account that during the installation of double-slot graphics card the PCI Express 2.0 x1 slot won’t be available.


Multi I/O capabilities are based on Nuvoton NCT6791D chip which controls the operation of the system fans, COM, LPT and PS/2 ports, as well as provides the monitors.


To support network connections there is GB LAN-controller Realtek 8111G. Network resource sharing and traffic can be realized by the proprietary Network iControl utility. 


Sound subsystem is based on HAD codec of 8-channel sound Realtek ALC887 that supports 2/4/5.1/7.1 sound systems.


According to concept 5X PROTECTION the interface panel of ASUS A88XM-PLUS model is made of high-quality stainless steel with layer of chrome oxide. It makes it more wearproof. Interface panel contains the following ports:  

  • 1 x HDMI;
  • 1 x DVI-D;
  • 1 x D-Sub;
  • 2 x PS/2 for mouse and keyboard connection;
  • 1 x LAN (RJ45);
  • 2 x USB 3.0;
  • 4 x USB 2.0;
  • 3 x audio port.

As you can see this interface panel has four USB 2.0 ports in contrast to two in the ASUS A88XM-A. As a result the only peculiarity is inconvenient connection of multichannel audio system. As for the advantages. Here is a good set of video outputs, as well as the opportunity to remove the COM and LPT ports on the interface panel using the appropriate connectors on the board.

Thus, the interface panel earns the praise due to the support of various peripheries as well as the presence of a sufficient amount of all popular video outputs and ports.



Cooling capabilities inside ASUS A88XM-PLUS case are standard. Four sockets for fan connection are used to organize cooling of the motherboard. One of them is used for the CPU cooling system, and the other three to activate the system of fans.



Motherboard ASUS A88XM-PLUS uses a modern pre-loader with UEFI basis. To provide the setting is possible using the mouse. Temperature and CPU voltage monitoring is displayed on UEFI BIOS main screen. Also in this section you can view the version BIOS, processor model and the capacity of installed RAM.


All overclocking settings can be found in “Ai Tweaker” section.
