Albatron PX845PEV Pro i845PE Based Mainboard

This is a budget model in the Albatron's line on i845PE, that is why you should expect much of it; and for more demanding users the company offers Albatron PX845PE Pro II


  • Package of the standard design; 
  • Documentation: user manual and a poster with brief installation steps - in English; 
  • Cables: FDD, ATA66/100/133; 
  • CD containing: 
    • drivers; 
    • PC-cillin 2000. 

The layout differs from a traditional one, but the differences do not add to the handiness though they make the board more narrow. As a result, the IDE connectors are in bad positions (behind PCI) and some others along the left board's edge, and when a video card is installed it's difficult to handle the memory modules. 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 7 capacitors of 2200 uF and 3 of 1500 uF. 

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 outputs; 
  • network controller based on the 3COM 910-A01 chip supporting 10BaseT/100BaseTX. 

Non-unsoldered connectors: none.

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 - 3 DDR SDRAM; expansion slots - AGP/ 5 PCI; I/O ports - 2 COM/ LPT/ 2 PS/2/ 6 USB 2.0; dimensions - 305x200 mm. 

Adjustment can be carried out with:

jumpers and switches Jumper to clear up the CMOS  
BIOS based on the AwardBIOS 6.00PG from Phoenix Setup of memory timings + CAS Latency, Active To Precharge Delay, RAS to CAS Delay, RAS Precharge
Setup of memory frequency + DDR/CPU = 1.5, 2, 2.5
Setup of AGP bus -  
Setup of PCI bus -  
Changeable scaler of AGP and PCI buses + CPU/AGP(PCIx2) = Auto, 1.5, 2, 2.5
Manual assignment of interrupts +  
Changeable FSB frequency + 100-248 MHz in 1MHz steps
Changeable CPU multiplier + x8-x50
Changeable core voltage + 1.1-1.85 in 0.025 V steps
Changeable memory voltage + Default, 2.6, 2.7, 2.8 V
Changeable chipset voltage -  
Changeable AGP bus voltage + Default, 16 V

We used the BIOS 1.05 beta as the latest available version. 

This high-quality board doesn't shine in functions, but it provides good overclocking settings, that is why it will be a good option for many.
