ASUS P8B75-M LX motherboard: Review & Specs

The main focus of our series of reviews on motherboards on high-level solutions, designed to provide users, gamers and overclockers. However, many in the assembly of a new PC do not need maximum functionality, and the main task – to save money. So we decided to evaluate the possibilities of one of the available models for LGA1155 platform – ASUS P8B75-M LX motherboard.

ASUS P8B75-M LX motherboard
This recent ASUS P8B75-M LX motherboard is based on chipset Intel B75 Express. However, despite the low rating index, it is slightly inferior to the same Intel N77.
The chipset belongs to business line of the seventh series featuring inherent support for USB 3.0 (four ports) and SATA 6 Gb / s (one port). Unlike other solutions, it has preserved the native PCI, that manufacturers can eliminate the need for additional controllers in the implementation of this archaic, but still in demand interface. Lack of support for SSD, caching in this segment are often critical.


Intel B75 is one of the most affordable chipset platforms of LGA1155, and the functionality of motherboards based on it is limited only by imagination manufacturers. Is not the king of the budget segment, especially if the user does not need separate excesses found in more expensive solutions?
The delivery, design, layout features

Considered ASUS P8B75-M LX motherboard is in a reduced form factor microATX (24.4 × 19.8 cm), so that comes in a small box. The delivery is extremely modest, and includes only the most necessary.
CPU VRM in ASUS P8B75-M LX is made on the basis of microcontroller uPI uP1652P on a “4 +1”, is used to supply power connector.
In the bottom of the ASUS P8B75-M LX board has closed an aluminium heat sink, SATA-ports (6-gigabit highlighted in color) and USB 3.0 socket to connect the front panel. Color-coded connectors for the buttons Power, Reset and indicative LED missing.
ASUS P8B75-M LX PCB has full-length PCI-E x16 (with Ivy Bridge processors available mode 3.0), two PCI-E x1 and one PCI.
CMOS reset jumper is not in the right place on this ASUS P8B75-M LX motherboard. Access to it is especially complex when installed in a system with cooler. To its credit, P8B75-M LX correctly resets UEFI installation options do not work, and have to use the jumper is extremely rare.
The sound system in this motherboard is the HDA-codec VIA VT1708S, gigabit network chip is implemented with Realtek RTL8111F.
The rear panel of ASUS P8B75-M LX presents a basic set of popular and relevant connectors.

– Combined PS / 2

– Four-port USB 2.0

– Two USB 3.0 ports

– The socket RJ45

– D-Sub and DVI (Single-Link)

– Three audio connectors
UEFI shell

UEFI-flash of the model meets the traditional headpiece, designed for beginners.

Advanced Settings is available when you press F7.
Impressive is the vast number of divisor of RAM, and a section dedicated to fine-tune the delay RAM, but its value in the absence of control voltage (including module DRAM) is negligible.

ASUS P8B75-M LX motherboard

ASUS P8B75-M LX motherboard has poor customization system (except the memory) and allows to force the PC to BCLK. We had hoped to go beyond the limitations UEFI, using the utility in Windows, but the usual TurboV EVO, not quite correctly identifying the current settings, refused to work.


If necessary, monitoring of PC, user can only monitor the temperature of the CPU and the chipset, as well as the speed of rotation of the two fans.
In the operation of the stand ASUS P8B75-M LX is stable in working with memory, Kingston KHX2133C9 AD3X2K2/4GX (2 × 2GB DDR3-2133).
Despite the excellent customization of subsystem RAM (UEFI available almost all possible subgroups and an extensive section setting delays), the real situation was much more mundane: ASUS P8B75-M LX works only with memory frequency of 1600 MHz.
Energy-saving features, like a related algorithm with Turbo Boost – the only way to get a free performance boost to the extent permitted by Intel. Control function to increase the multiplier is locked.


Heat sink in the process heated up to 55.3 ° C (at room temperature 25 ° C), which is far from the critical values. Readings are taken with contactless thermometer.
Integrated graphics core supports monitors, the resolution of which is less than 1920 × 1200 pixels.


The rest of the ASUS P8B75-M LX showed complete stability in work and live up to expectations.

Total Performance
ASUS P8B75-M LX is captivating simplicity and more democratic than the price. Nice to see a product that costs ~ $ 60 features recently inherent only much more expensive solution (it is first of all about USB 3.0 and SATA 6 Gb / s). Intel B75 Express chipset can be a real budget alternative H77: Smart Response technology and a greater number of ports and interface connectors need not all users, fine-tuning the system based on the logic involved in only one. The only thing to remember – the level of equipment of ASUS P8B75-M LX is fully correlated with the price, so the decision in question is a great way to use architecture Sandy / Ivy Bridge in the entry-level PC. Need more – consider models based on other chipsets (although no special selection – talking about low-middle motherboards based on Intel Z77). Otherwise, we face a great “workhorse”, completely and fully justifies its tasks.

+ Digital and analog video output

+ Availability of USB 3.0, SATA 6Gb / s, PCI slot

+ Support for all current Ivy Bridge processor family

+ Cost

– Lack of color-coded front panel connectors

This was all regarding the review of ASUS P8B75-M LX, stay tuned for more.
