Features of design ABIT IT7-MAX2

Fig. 3. Design of motherboard ABIT IT7-MAX2

The design of motherboard ABIT IT7-MAX2 developed and released by Abit corporation, as a whole corresponds to the referens-design of similar products created and recommended by corporations, releasing sets of system logic.

In the motherboard architecture, except chips of Intel and Abit, units of such corporations, as Abit RealTek, Avance Logic (division RealTek) and others are used.

The functional mode of memory modules DDR SDRAM can be or synchronous — clock rate coincides with frequency FSB, or asynchronous — clock rate differs from frequency FSB. For a choice and installation of demanded functional modes of the processor, memory and input/output arrangements appropriate BIOS Setup choices use.

Usage as a part of the motherboard of chip High Point HPT 374 allows or to increase number of hooked up arrangements IDE, or to use possibilities RAID.

The special adapter besides, a part of a package provides compatibility of perspective interface Serial ATA with becoming outdated ATA (IDE). This adapter is named Serillel. These adapters provide hooking up through appropriate cables to Serial ATA plugs of arrangements ATA extended now. ROM/R/RW CD, similar CDs concern the given arrangements drives DVD, etc., as is known, widespread HDD .

For enthusiasts of dispersal there is a possibility of installation of the forced functional modes of the processor. It is carried out by rise of frequency of processor bus FSB (overclocking) and memory buses, and also a choice of best values of parametres of operation of DDR SDRAM units. For the purpose of rise of stability of system operation chip ICH4 providing interfaces of input/output, is supplied by the traditional heat sink providing maintenance of an optimal temperature mode of its maintenance.

Levels of powers, temperature and operation of the fans which are a part of coolers, resources hardware monitoring inspect. Built in a motherboard construction the two-bit indicator facilitates the analysis of passing of stage POST.

Integrated into structure of motherboard ABIT IT7-MAX2 network tools allow to include easily the computer through built in RJ45 (LAN plug in local area network structure.

And as to an estimation of the main operation parametres of the described motherboard it is necessary to mark, that at performance of numerous, durable tests card ABIT IT7-MAX2 worked steadily not only in regular, but also in a wide band of the forced modes. This circumstance, by the way, is firm feature of products of this corporation. To estimate dependability of the tested card rather difficultly on the basis of operation of a unique accessible copy, however traditionally this parametre is high enough. For more exact answer to this question it is necessary to access or to the computer corporations realising this product, or it is direct to the manufacturer — Abit corporation.

Motherboard ABIT IT7-MAX2 is given by the Moscow representation of Abit corporation.
