The design of motherboard ABIT KD7 developed and released by Abit corporation, as a whole corresponds to referens-design of similar products. Especially it concerns the most critical areas of the card on which the units influencing productivity and stability of operation are allocated. First of all it concerns the processor, dynamic storage, the videoadapter and VRM. Here it is necessary to remind, that referens-design of motherboards, as a rule, develop and recommend to application the corporations releasing sets of the system logic and usually working in the close contact electrode to manufacturers of processors.

In the motherboard architecture units of such corporations, as VIA, Advance Logic (division RealTek), Winbond 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.

If necessary except traditional drives of interface ATA, together with motherboard Abit KD7-G it is possible to use the arrangements which are hooked up through interface Serial ATA 150 (1,5 Gbytes/c). For this purpose controller Silicon Image SIL3112A is integrated into card structure (on the card this controller is closed by a sticker with the motherboard name — KD7-G. Optsionalno in a package the special adapter providing translation of interfaces ATA/66/100 and Serial ATA is applied. This adapter is named by Abit Serillel corporation. The given 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): the band of change of frequency of the system bus (FSB) is equaled from 100 to 250МГц. There is a possibility of installation of synchronous and asynchronous functional modes of a subsystem of memory, and also a choice of best values of parametres of operation of DDR SDRAM units.

For rise of stability of system operation on the raised frequency functional modes there is a possibility of installation of higher on matching with regular modes of values of power on a processor kernel: peak value Vcore can be increased to 2,325 Century

Besides, there is a possibility of increase in power on memory modules — Vmem. The band of change with step 0,1 In is equal from 2,55 In to 3,25 Century

For the purpose of rise of stability of system operation chip North Bridge is supplied by the strengthened resources of maintenance of an optimal temperature mode in which quality uses not only the heat sink, but also the fan.

Levels of powers, temperature and operation of the fans which are a part of coolers, resources hardware monitoring inspect.

Integrated into structure of motherboard ABIT KD7 network tools allow to include easily the computer through built in RJ45 (LAN plug in local area network structure. Feature of motherboard Abit KD7-G is usage of controller Ethernet Gigabit providing a peak transfer rate on a twisted pair to 1 Gbit/with.

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 KD7-G worked steadily not only in regular, but also in the forced modes. To estimate dependability of the tested card rather difficultly on the basis of operation of a unique accessible copy. For the 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.

In summary it is necessary to remind once again, that a correct and optimal choice of the motherboard with an appropriate chip set — pledge of high efficiency of the computer, its reliable and a stable operation, and also frictionless upgrade.
