Chaintech 9EJL1 (i845E) Mainboard (Apogee series) 

This is one more board from the Apogee line. In the description of the Chaintech 7VJL board you can look though its functions and accessories, and the today's model will arouse the same interest among supporters of the Socket 478. 


  • Package of a stylish design with a handle; 
  • Documentation: user manual in English; 
  • Cables: 2 ATA66/100/133 and FDD - all of them are covered in green cambric for better ventilation inside; 
  • CBOX bracket with 4 USB 2.0/1.1 connectors and Audio-In/Out; 
  • Bracket for the rear computer panel with Rear and Bass/Center connectors; 

  • Body Theater headphones emulating a 4.1 audio system; 
  • Thermo grease; 
  • 4 CDs containing: 
    • drivers; 
    • user manual in PDF; 
    • Realtek CPUBoost (for changing a FSB frequency from Windows); 
    • Norton Internet Security 2002; 
    • Norton Antivirus 2002; 
    • Adobe ActiveShare; 
    • Adobe Acrobat Reader; 
    • Adobe eBook Reader; 
    • ImageMore; 
    • ThizLinux 6.0 (Asian & European version). 

The layout is similar to the junior 9EJL0: audio-ins are located in front of the PCI and AGP slots and the FDD is behind them. It's not difficult to reach jumpers when the board is already installed. Their functions are shown on the textolite.

The 3-channel switching voltage regulator incorporates 7 capacitors of 2200 uF and 3 of 1200 uF.

The following controllers are integrated: 

  • audio controller based on the C-Media CMI8738/PCI-6ch-LX chip with a connector for front audio inputs/outputs, an SPDIF connector and the support for 5.1 audio systems;
  • network controller based on the Realtek RTL8100B supporting 10Base-T/100Base-TX. 
The ITE IT8712F-A I/O controller supports a smart card reader (the connector is provided). 

Non-unsoldered connectors: AUX Power connector, AC'97 codec and IDE RAID controller with connectors. 

The system monitoring is supported by the ITE IT8712F-A chip. What is controlled: 

  • processor voltage, +1.5, +3.3, +-5 and +-12 V, VBAT, +5 V Standby; 
  • speed of 2 fans; 
  • temperatures of the processor (a built-in sensor), and the board (a built-in sensor).
There are 2 connectors for adjustable 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 - 305x230 mm.

Adjustment can be carried out with: 

jumpers and switchesJumper to clear up the CMOS 
Jumper for starting up computer from a PS/2 keyboard 
Jumpers for starting up computer from USB keyboard 
Jumper for enabling/disabling audio controller 
Jumper for enabling/disabling network controller 
BIOS based on AwardBIOS 6.00PG from PhoenixSetup of memory timings+CAS Latency, Active to Precharge Delay, RAS to CAS Delay, RAS Precharge
Setup of memory frequency+Auto, DDR200, DDR266
Setup of AGP bus- 
Setup of PCI bus- 
Changeable scaler of AGP and PCI buses+AGP = Synch., 66, 75 and 88 MHz
Manual assignment of interrupts+ 
Changeable FSB frequency+100 - 255 MHz in 1MHz steps
Changeable CPU multiplier+x8 - x50
Changeable core voltage+1.1 - 2.0 V in 0.025V steps to 1.85 V, further in 0.05V steps
Changeable memory voltage+Default, 2.65, 2.8, 2.95 V
Changeable chipset voltage- 
Changeable AGP bus voltage+Default, 1.65, 1.8, 1.95 V

We used the latest available version of the BIOS of 07/05/2002. 

The richest accessory package and a wide range of adjustable features coupled with a high speed even with the default parameters are the strongest points of the board (as well as of the whole Apogee series).
