After expansion lineup Intel Core 2 Duo and the subsequent sharp drop in prices for processors of this family today prices for some of them are less than $ 100, which made them a very attractive solution for creating not only high-performance and gaming stations, but also inexpensive computer systems aimed at the mass user , and even budget PCs. This, in turn, has led to a demand for inexpensive motherboards that could serve as the basis for such budget systems... In response to market needs, Hon Hai Precision Industry, which manufactures components under the Foxconn brand, has introduced a new Foxconn 45CM-S motherboard, which we will tell our readers about.

The Foxconn 45CM-S motherboard is made in the microATX form factor (size - 24.4x22.4 cm) on a dark blue textolite, traditional for Foxconn products (Fig. 1). It is based on the Intel 945GС Express system logic set (Intel 945GС Express + ICH7), the capabilities of which are complemented by the ITE IT8718F I / O controller. Although, according to the official specs Intel, this chipset is limited in its capabilities, being a stripped-down version of the popular Intel 945G Express Integrated Chipset (maximum FSB frequency of 800 MHz, and memory bus frequency is limited to 667 MHz), Hon Hai Precision Industry specialists our ability to use its hidden reserves. Thus, this motherboard supports the full range of Intel LGA775 processors, including both single-core Intel Celeron D series processors and Intel Pentium 4 5xx and 6xx, as well as dual-core Intel Pentium D 8xx and 9xx, as well as processors from the new Intel Core 2 Duo family of processors, and provides the ability to operate the system bus with a frequency of 533, 800 or 1066 MHz. To install system memory modules (it is assumed that unbuffered memory modules of DDR2 SDRAM 400/533 or 667 standard will be used), the board has two DIMM slots. The memory subsystem can operate in both one- and two-channel modes. The maximum system memory supported by the board is 2 GB.

Rice. 1. Foxconn 45CM-S

Foxconn 45CM-S motherboard has an integrated graphics core Intel Graphics Media Accelerator 950 (Intel GMA950) fully supports API DirectX 9. It has a 256-bit architecture and runs at 400 MHz. Integrated for your needs graphics processor uses system memory, and thanks to Dynamic Video Memory Technology (DVMT), the amount of video memory is dynamically changed and can reach 192 MB. This graphics solution provides the ability to display images with a maximum resolution of 2048x1536 pixels and a color depth of 32 bits, that is, it meets the requirements for working with the rapidly gaining popularity of HD-video (High Definition) with a resolution of 720 or 1080 horizontal lines. It is also worth noting here that this integrated graphics core supports the so-called High Definition Hardware Motion Compensation technology, which hardware accelerates the playback of MPEG-2 video files, which is especially important when playing back HD video recorded at high bitrate. In addition, with the Advanced Digital Display 2 (ADD2) card installed in the PCI Express x16 slot, the graphics Intel core GMA950 supports additional graphical interface(it can be DVI or S-Video TV Out). If the capabilities of the graphics core are still not enough, then the user can always install a discrete PCI Express x16 slot in the already mentioned slot. graphics card... By the way, besides this slot for installation additional cards expanding the capabilities of the motherboard, there are two more PCI slots and one PCI Express x1 slot.

Foxconn 45CM-S provides the user with a Realtek RTL8100C 100 Mbps Ethernet controller to organize network connectivity. The audio system here is implemented by a combination of the HDA (High Definition Audio) controller integrated into the ICH7 and the Realtek ALC883 audio codec, which provides the ability to reproduce sound in 5.1 format.

This review will be devoted entirely to such a computer component as the Foxconn N15235 motherboard. It is on the example of this component that strong and weak sides products of this manufacturer. This will allow you to make recommendations regarding the purchase of his products.

Foxconn at a glance

Assembling various electronic devices under the order is the main specialization of Foxconn. Motherboards, graphics adapters, smartphones, mobile phones- this is not a complete list of equipment that are manufactured at the production facilities of this company. Moreover, the list of Foxconn clients includes Apple, Asus, Gigabyte, and MSI. With such a wealth of opportunities for assembly and testing of manufactured equipment, this company decided to expand the scope of its business. This is how a series of motherboards under the Foxconn brand appeared. One of them is N15235.

What kind of PC is this motherboard suitable for?

At the time of its release, the Foxconn N15235 motherboard was focused on installing the most powerful processors. It was also possible to supplement such a computer system with high-performance graphics adapter... All this in total made it possible to create the most productive personal computers on the basis of this solution. It could have been work station, and a graphics station, and gaming computer capable of running any of the most demanding toys existing at that time. This same motherboard could successfully act as a link in mid-range and entry-level PCs. Only in this case it was not entirely justified to use such an expensive and functional computer component. Its main purpose is to create high-performance computer systems.

The location of the elements of the system board

The Foxconn motherboard of this model is manufactured in the microATics form factor. Its dimensions are 9.6 inches by 8.0 inches. Almost in the middle of the upper part of the product is the LGA 775 processor socket. To the left of it is the CPU, which consists of several solid-state capacitors and semiconductor regulators. Farther away, at the very edge of the board, are the wired interface ports. To the right of the socket are 2 slots for installing RAM, behind which are the power connectors and IDE drives. Directly under the processor socket for installing the CPU is the chipset. Expansion slots are displayed below it. To the right of them are located south bridge, battery "BIOS" and ports for connecting SATA drives. Here, at the very edge, there is a commutation connector for the front panel of the PC case.

Chipset and its characteristics

The Foxconn N15235 motherboard is based on a two-chip set. The description of this product indicates that the G31 from Intel is acting as the northbridge in this case. Its key component is the memory controller. The thermal package of this silicon crystal was 17 W, and the values ​​of the system bus frequency in this situation could be 800 MHz / 1066 MHz / 1333 MHz. In this case, ICH7 comes in as the same. Its main task is to connect peripheral devices and controller cards in expansion slots.

Socket. What processors can be installed in it?

An impressive list of CPUs supported by the Foxconn N15235 motherboard. The description of this product indicates the presence in this list of all chips oriented to be installed in this processor socket. The most productive solutions of this platform are the quad-core "Cor 2 Quad". A step lower from the position of performance is "Cor 2 Duo", in which the number of computing units is reduced to two. The Pentium Dual Core CPUs had an even lower level of performance. The number of cores they had was exactly the same, but the frequencies were reduced and the cache memory was cut. The most affordable chips with two computational modules for the LGA 775 were Celeron Dual Cor. They had even less cache than older CPU models. And the frequency has been further reduced. The segment of single-core processors was occupied by Pentium 4 and Celeron. Any of the above models with a chip from Intel could be installed in such a motherboard. But still, taking into account its positioning and level of functionality, it was preferable to use it in combination with 2 and 4-core CPU models of this platform.

Peripheral set

The list of wired interface ports on this motherboard was as follows:

    2 ports of PS / 2 format for connecting a pointing device to a PC (it was green) and a keyboard (for these purposes, a purple port was used).

    One COM port (its second name is serial) and one LPT port (or, as it is also called, parallel). With their help it was possible to carry out switching various devices input / output to a computer system (plotter, scanner, printer).

    4 ports of the "YUSB" format, if necessary, could replace the COM-port or LPT-port for connecting similar input / output devices to the computer system.

    Also, this product was equipped with one RJ-45 port for connecting a PC to a computer network.

Expansion slots

The Foxconn N15235 motherboard was equipped with an excellent set of expansion slots. Its characteristics indicate the presence of such of them:

    PCI Express 16 X is the only and main slot for installing a discrete graphics accelerator that processes images displayed on the display.

    Also, this motherboard was equipped with one PCI Express 1 X slot. The latest modifications of additional controllers (for example, a TV tuner) should be installed in it.

    But to install outdated controller modifications, this product was equipped with 2 PCI expansion slots at once.

Regarding the expansion slots of this board, one important feature should be noted: if you use a powerful video card in such a computer system, which takes 2 expansion slots at once, then it will be impossible to install an additional expansion controller in the PCIExpress 1 X slot.

RAM

Only modules of one type of RAM were supported by the Foxconn N15235 motherboard. The characteristics indicated support for "DDR2". Moreover, it was possible to install only the strips "DDR2-667" and "DDR2-800". It was preferable to use exactly the latest modification of RAM, which allowed in practice to obtain a certain increase in performance. Maximum amount RAM, which could be installed in such computer system was equal to 4 GB. This limitation was primarily imposed by the CPU, which could address this amount of RAM at most. The RAM controller itself was a key component of the north bridge of the chipset. It was two-channel. Accordingly, the use of two 512 MB strips instead of 1 1 GB module made it possible to get even greater performance gain, which could reach 15 percent.

Connecting the front panel of the system unit

As noted earlier, the front panel of the case of the system unit of a personal computer is connected in the lower right corner of the system board. All necessary designations are marked next to the corresponding connectors. So this motherboard from Foxconn cannot stand out as something unusual against the background of similar products. Connection is provided for the following elements of the front panel:

    Speaker (system speaker for signaling events).

    Power Switch (PC power button).

    Power LED (indication of turning on the PC).

    Reset Switch (button for forced restart of the computer system).

    HDD LED (operation indication hard disk or solid state drive).

Power supply and power supply of the motherboard

The Foxconn N15235 motherboard is connected to the power supply via two connectors. One of them is ATX12V, which consists of 24 pins. The second, in this case, provides additional power to the central processing unit and consists of only eight contacts. Also, when equipping a PC with a high-performance graphics accelerator, it was necessary to connect the third power connector to it.
