85DR2 (i845E) Mainboard
This is one more mid-level board but from the well-known manufacturer.

There are several complains about the layout: audio-ins, IDE and FDD connectors
are around the PCI slots, and the power supply connector is tucked in between
the AGP slot and the processor socket. It can be difficult to reach some jumpers
when the board is already installed. Their functions are shown on the textolite.
The 3-channel switching voltage regulator incorporates 8 capacitors of 2200
uF and several less capacious ones.
The following controllers are integrated:
The board supports the Red
Storm Overclocking technology (auto overclocking from BIOS) and SafeGuard (protection
of the board from video cards of +3.3V voltage - it must be disabled in case of
PCI video cards).
- audio controller based on the chipset's capabilities and ALC650 AC'97
codec supporting 5.1 audio systems.
If you insert into the AGP slot a 3.3V video card the
red LED will go on notifying on protection from such cards. A red LED located
between the processor socket and memory modules informs on power supplied to the
memory. The back side of the board houses a metallic plate that prevents the textolite
from distortion when massive coolers are installed.
connectors: network controller and RJ45 connector, IDE controller and its connectors,
CNR slot, smart card reader's connector, connector for front audio I/Os.
The system monitoring is supported by the Winbond WT83627HF-AW chip. What is
There are 2 connectors for adjustable connection
of fans and 1 for nonadjustable connection.
- processor voltage, +3.3, +-5 and +-12 V, VBAT, +5 V
- speed of 2 fans;
- temperatures of the processor
(a built-in sensor), the board (a built-in sensor) and an external thermistor
connected to the board.

We used the
latest available version of the BIOS - AF1.2.
There is nothing much we
can say about the board: minimal functions, an average speed, unimpressive adjustability.
It's only speed and quality that can be interesting for certain users.
