Tyan Trinity 845e (S2099A) (i845E) Mainboard

Usually solutions of this company are not trivial. But the today's board is an entry-level model in the line, that is why it doesn't have any interesting features. 


  • Package of an austere design; 
  • Documentation: user manual in English; 
  • Cables: 1 ATA66/100/133 and FDD; 
  • Bracket for the rear computer panel; 
  • CD containing: 
    • drivers. 

The layout is far not conventional, but the drawbacks are typical: audio-ins are in front of the PCI, and the IDE and FDD are behind them. When a video card is installed it's difficult to handle the memory modules, and the cables going to the power supply connectors stretch right over the processor socket. It's not difficult 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 8 capacitors of 3300 uF and several less capacious ones. 

The following controllers are integrated: 

  • audio controller based on the chipset's capabilities and Avance Logic ALC650 AC'97 codec supporting 5.1 audio systems and having connectors for front audio inputs/outputs and for SPDIF.  

Non-unsoldered connectors: video adapter's chip, video memory chips, network controller and 2 RJ45 connectors, IDE RAID controller and its connectors. 

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

  • processor voltage, +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 - 4 DDR SDRAM; expansion slots - AGP Pro/ 5 PCI; 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  
BIOS based on the Phoenix AwardBIOS 6.00PG Setup of memory timings -  
Setup of memory frequency + Auto, DDR200, DDR266
Setup of AGP bus -  
Setup of PCI bus -  
Changeable scaler of AGP and PCI buses -  
Manual assignment of interrupts -  
Changeable FSB frequency + 100-165 MHz in 1MHz steps
Changeable CPU multiplier -  
Changeable core voltage + +0.025, +0.5, +0.075 V
Changeable memory voltage + +0.05, +0.1, +0.15 V
Changeable chipset voltage -  
Changeable AGP bus voltage -  

We used the BIOS 1.05 as the latest available version. 

According to its functions this board belongs to the entry level but its price is not moderate. The company positions it as a solution for servers and workstations stressing on its reliability and error-free operation, but I still don't see lots of prospects for such a restricted solution.
