The design of the motherboard of Intel D845PEBT2 as a whole corresponds to referens-design of similar products. It is necessary to mark, that design of motherboards, especially it concerns the most critical areas on which are allocated the processor plug, chip MCH, units of dynamic storage and AGP plug, usually forms and it is recommended the corporations developing and releasing sets of the system logic. In this case the given initiative belongs to the implementator of a chip set i845PE to Intel corporation.

The functional mode of memory modules DDR SDRAM as it is accepted and is realised now practically in all motherboards, DDR SDRAM can be or synchronous — clock rate coincides with frequency FSB, or asynchronous — clock rate differs from frequency FSB.

From features of the architecture it is necessary to mark presence of the controller of the sound realised on the basis of a chip set and codec AC ' 97 Analog Devices AD1980. It provides possibility of hooking up of audiosystems 5.1. Controller SATA RAID realised on the basis of chip Silicon Image Sil3112ACT144 and providing possibility of creation RAID of levels 0 and 1 with support of SATA150 protocol, and also the network controller with support 10BaseT/100BaseTX is Besides, used. Integrated into structure of the motherboard of Intel D845PEBT2 network tools allow to include easily the computer through built in RJ45 (LAN plug in local area network structure.

In a two-channel impulse surge protector of the processor 3 capacitors on 3300 mkf, 4 on 1000 mkf and some less capacious capacitors are applied. Usually in motherboards fourline converters use three, and even. But the implementator of standards VRM — Intel corporation has considered sufficient for the product of two-channel solution.

The power +5 In in mode Standby shows a light-emitting diode on the motherboard.

In the architecture of the motherboard by means of chip SMSC LPC47M172-NR possibilities of the hardware monitoring providing the control over supply voltages and operation of fans are realised. By the way, in the given card autocontrol of the fan which is responsible for temperature in a system unit is realised.

From the most interesting features of the motherboard of Intel D845PEBT2 it is necessary to mark the fast loading provided with processing technique of Intel Rapid BIOS boot. However, this feature is characteristic for all motherboards of Intel. However, since the card of Intel D845PEBT2, the corporation has taken off embargo from usage in the products of the forced modes, having realised dispersal in this card. However, the band is limited by values:-2 % of,-1 %, +1 %, +2 %, +3 %, +4 % from a rated frequency. This mode is named Burn-In Mode and is taken up a position for experts.

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 the card of Intel D845PEBT2 worked steadily as it usually and is characteristic for products of this manufacturer. To estimate dependability of the tested card rather difficultly on the basis of operation of a unique accessible copy, however it is traditional for products of the corporation of Intel this parametre it 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 of mother chamber — Intel corporation.

The card can be recommended a wide range of users which does not interest possibilities of extremal modes of dispersal both which prefer dependability and stability of operation.
