The layout has several typical drawbacks: audio-ins are in front of the PCI
slots and IDE RAID connectors are behind them, and when a video card is installed
it's difficult to handle the memory modules. But it's not difficult to reach the
jumpers when the board is already installed. Their functions are shown on the
The 3-channel switching voltage regulator incorporates 6 capacitors
of 3300 uF and 3 of 1500 uF.
The following controllers are integrated:
are power and reset buttons onboard.
- audio controller based on the chipset's capabilities and Avance Logic
ALC650 AC'97 codec supporting 5.1 audio systems;
- IDE RAID
controller based on the HighPoint HPT372 chip, supporting RAID 0, 1 and 0+1 via
the ATA133 and SerialATA protocols (with the Marvell 80i8030-TBC chip);
IEEE 1394 bus controller based on the Realtek RTL8801 chip.
Non-unsoldered connectors: none.
The system monitoring is supported by the ITE IT8705F chip. What is controlled:
There are 3 connectors for adjustable
connection of fans.
- processor voltage, +3.3, +-5 and +-12 V and VBAT;
of 2 fans;
- temperatures of the processor (a built-in sensor) and
the board (a built-in sensor).
