8KNXP Ultra (i875P) Mainboard
This is the most expensive board on this chipset, and one more example of a
High-End solution sporting perfect functionality and pretty good performance.
- Package of a new design laminated with plastic
with a holographic effect;
- Documentation: user manual, installation
manual for IDE RAID, installation manual for SCSI RAID, poster with brief installation
steps - all in English;
- Cables: FDD, SCSI for 5 devices, 2 SATA,
- 2 brackets with 2 USB ports each;
Bracket with Rear, Center/Sub and S/PDIF-Out (Coaxial and TosLink);
- CD with:
- Adobe Acrobat Reader;
- Norton Internet
- Gigabyte @BIOS;
- Gigabyte DMIView;
- Gigabyte FaceWizard;
Windows Utility Manager;
- Gigabyte IA Panel Utility.
In spite of a great number of integrated components, the layout is well arranged,
though it was impossible to avoid placing all of three RAID (IDE, SATA and SCSI)
behind the PCI slots, and 6 memory slots left almost no space around, that is
why it can be difficult handle the memory. Besides, the audio-ins are in front
of the PCI. It's also uneasy to reach the only jumper when the board is already
installed. Its functions are shown on the textolite.
The 3-channel switching
voltage regulator incorporates 4 capacitors of 3300 uF and several less capacious
ones. With the external DPS2 module used, the processor gets a 6-channel voltage
regulator of 6 capacitors of 3300 uF and several less capacious ones. Also, there
are voltage regulators for the AGP bus (1 1000 uF) and memory bus (8 of 1000 uF).
- audio controller based on the chipset
and Analog Devices AD1985 AC'97 codec; 5.1 audio system supported, front audio
inputs/outputs and SPDIF connectors provided
- network controller
based on Intel 82547EI (Kenai II CSA) chip supporting 10BaseT/100BaseTX/1000BaseT
- IDE RAID controller based on the ITE IT8212F
chip supporting RAID 0, 1 and 0+1 on the ATA133 protocol;
SCSI RAID controller based on the Adaptec AIC-7902W chip supporting RAID 0 and
1 on the Ultra320 protocol.
- DualBIOS (Flash EEPROM backup chip with the BIOS copy);
DPS2 (external VRM module ensuring more stable operation of the processor).
a video card not supporting +1.5 V is inserted the respective LED will warn you
about it. Another LED let you know whether voltage is supplied to the memory modules.
Non-unsoldered connectors: none.
System monitoring is supported by
ITE IT8712F-A chip. It controls:
- processor voltage, +3.3, +5 and
- speed of 3 fans;
- temperatures of the processor
(built-in sensor) and the board (built-in sensor).
are 2 connectors for adjustable and 2 for unadjustable connection of fans (one
of them is connected to a fan on the north bridge's heatsink).
board's characteristics: memory slots - 6 DDR SDRAM; expansion slots - AGP
Pro/ 5 PCI; I/O ports - 2 COM/ LPT/ 2 PS/2/ 8 USB 2.0; dimensions - 305x245 mm.

We used the F5 and M8 BIOS versions.
I hope the new BIOS version will boost its performance, and
then we will have nothing to find fault with. However, even now I can recommend
this board for those who need a rich and even unique functionality. It's not a
king of overclocking, though you may use its richest overclocking settings to
get better scores.
