Canyon 9IGA (i845G) Mainboard

I have almost nothing to say about this company: we just found out that its technology of board production has the ISO9001 standard certificate; and the boards are produced in Taiwan and China. It's the first time we test products of this company and I must say we found no reasons why we should treat it as an outsider. If you look attentively at the photos of the today's boards you will get an idea on this manufacturer. 


  • Package of a low-key green design; 
  • Documentation: user manual in English ; 
  • Cables: 1 ATA66/100/133 and FDD; 
  • Bracket with SPDIF-In/Out (Coaxial) connectors; 

  • Bracket with a serial port and a Game port; 
  • Bracket for the rear computer panel; 
  • CD containing:
    • drivers; 
    • Boostek; 
    • DirectX 8.1. 

The layout is quite handy, only audio-ins are between the PCI slots, and when a video card is installed it's difficult to handle memory modules. And 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 4 of 1200 uF. 

The following controllers are integrated: 

  • audio controller based on the Avance Logic ALC650 AC'97 codec supporting 5.1 audio systems and with a connector for front audio-ins and an SPDIF connector. 
The POST controller located onboard has 4 LEDs informing about problems occurred during rebooting. In the StandBy mode the LEDs located between the first and second PCI slots and next to the memory modules go on. If you insert a 3.3V card into the AGP slot the red LED will go on. 

Non-unsoldered connectors: flash card reader interface controller and its connectors, network controller and RJ45 connector. 

The system monitoring is supported by the Winbond W83627HF-AW chip. What is controlled: 

  • voltage of processor, AGP bus, +3.3, +5 and +/-12 V, VBAT and +5 V Standby; 
  • speed of 3 fans; 
  • temperatures of the processor (a built-in sensor) and the board (a built-in sensor). 
There are 2 connectors for adjustable and 1 for unadjustable connection of fans. 

Brief characteristics of the board: memory slots - 2 DDR SDRAM; expansion slots - AGP/ 6 PCI /CNR; I/O ports - 2 COM/ LPT/ 2 PS/2/ 6 USB 2.0; dimensions - 305x245 mm. 

Adjustment can be carried out with:

jumpers and switches Jumper to clear up the CMOS  
Jumper for starting up computer from PS/2 keyboard  
Jumpers for starting up computer from USB keyboard  
Jumpers to choose a FSB frequency Auto, 100 and 133 MHz
Jumper for choosing a connector for the 6th USB port CNR/Onboard
BIOS based on the AwardBIOS 6.00PG version from Phoenix Setup of memory timings + CAS Latency, Active To Precharge Delay, RAS to CAS Delay, RAS Precharge
Setup of memory frequency + Auto, DDR200, DDR266, DDR333
Setup of AGP bus +  
Setup of PCI bus -  
Changeable scaler of AGP and PCI buses + Auto, 33/66, 37.5/75, 44/88 MHz
Manual assignment of interrupts -  
Changeable FSB frequency + 100-200 MHz in 1MHz steps
Changeable CPU multiplier + x8-x50
Changeable core voltage + from +0.025V to +0.15 V in 0.025V steps
Changeable memory voltage -  
Changeable chipset voltage -  
Changeable AGP bus voltage -  

We used the latest available version of the BIOS of 17/04/02. 

There is nothing much we can say about this board, except that it looks very similar to another board from the today's bunch, but at the same time it has wider capabilities but weaker functionality.
