DFI LANParty Pro875 Mainboard (i875P)

June 15, 2003

Every company tries to attract attention with a better software suite, integrated controllers or accessories. In this case the company has created a dedicated niche for its product which will certainly catch the eye of even those who are indifferent to this niche. So, meet LANParty boards! According to DFI, there are two aspects why they named it LAN Party - a PC transportation set (you can you can rent a computer club for LAN Party gaming or use your PC as a multimedia station outside your home), and club-like bright glow in UV rays. 

The box contents: 

  • Package: a big bright box which demonstrates how the PC-Transpo set could be used; :)
  • PC-Transpo: straps for PC transportation (the PC case is put into something like a backpack which also has pockets for a keyboard, mouse etc.);



  • Documentation: User Guide in 5 languages, brief installation manual and IDE RAID description in English;
  • Cables: 2 Serial ATA (without power supply adapters), 2 ATA66/100/133 and FDD - the latter connectors are shielded and covered with transparent orange cambric;



  • Bracket with S/PDIF-In/Out (Coaxial);
  • Bracket with a Game port;
  • 5" FrontX panel with Mic-In, Speaker-Out and 2 USB ports;



  • I/O shield;
  • Thermal grease;
  • 2 diskettes with drivers for IDE and SATA RAID;
  • 2 CDs with software including:
    • drivers;
    • user guide in PDF;
    • Adobe Acrobat Reader;
    • Award WinFlash 1.54;
    • RadarSync;
    • McAfee VirusScan Online;
    • Winbond Hardware Doctor;
    • InterVideo WinDVD;
    • InterVideo WinRip.

The layout is convenient but, still, there are some drawbacks: the IDE RAID and FDD are behind the PCI slots, and audio-ins are in front of them. It can be difficult to reach some jumpers when the board is already installed. Jumpers description is provided on the PCB. 

The 3-phase CPU voltage regulator includes 8 capacitors of 2200 uF and 4 of 1500 uF. There are also voltage regulators of the AGP bus (1 capacitor of 2200 uF and several less capacious ones) and of the memory (2 of 1500 uF). 

Integrated controllers: 

  • audio controller based on the C-Media CMI9739A AC'97 codec; 5.1 audio system supported, front audio outputs and S/PDIF connectors provided
  • network controller based on the Intel 82547EI (Kenai II CSA) chip; 10/100/1000 Base-T (Gigabit Ethernet) supported;
  • IDE RAID controller based on the Highpoint HPT372N chip supporting RAID 0, 1, 0+1 and 1.5 (0+1 on two discs - half of each disc is taken for backup information from the other) by the ATA133 protocol.

+5 V supplied in the StandBy mode is indicated with the red LED. The POST controller monitors boot up process with 4 more LEDs. Also, there are power and reset buttons onboard. 

No wasted space for components that didn't get included in the final design. 

System monitoring is supported by Winbond W83627HF-AW chip. It controls: 

  • processor, AGP bus voltages, +3.3, +5 and +-12 V, VBAT and +5 V Standby;
  • rotation speed of 3 fans; 
  • temperatures of the processor (built-in sensor) and the board (built-in sensor).

There are 2 connectors for regulated and 3 for unregulated connection of fans. 

Summary: memory slots - 4 DDR SDRAM; expansion slots - AGP/ 5 PCI; I/O ports - 2 COM/ LPT/ 2 PS/2/ 8 USB 2.0; dimensions - 305x245 mm.

BIOS based on Phoenix AwardBIOS 6.00PG Setup of memory timings + CAS Latency, RAS Precharge, RAS to CAS Delay, Active to Precharge Delay
Setup of memory frequency + Auto, 266, 320, 400 MHz (at FSB 800 MHz)
Setup of AGP bus -  
Setup of PCI bus -  
AGP/PCI frequency setup + AGP(PCIx2) = Auto, 66 MHz
PCI IRQ manual assignment +  
FSB frequency setup + 100-400 MHz in 1MHz steps
CPU clock ratio + x8-x50
Core voltage control + from +0.05 to +0.35 V 
Memory voltage control + 2.5-2.7 V in 0.1V steps
Chipset voltage control -  
AGP bus voltage control + 1.5 and 1.6 V 

We used the BIOS of 16.05.03 as the latest available version. 

In the express performance tests with the BIOS version indicated above the board scores the following results: 

Test ABIT IC7-G ASUS P4C800 Deluxe DFI LANParty Pro875
WinAce archiving (min:sec) 11:45 10:06 11:50
Return to Castle Wolfenstein, Fast@800x600x16 (fps) 235 252 231
Return to Castle Wolfenstein, High@1280x1024x32 (fps) 181 189 180

It's still far from the leading ASUS P4C800 Deluxe (its performance was discussed here), but in general, its scores are at the level of most i875P based boards. 

As a result, we have a high-quality board with good functionality and a couple of unique image capabilities. 

Test results of other i875P based boards (for comparison):
