ABIT NF7-M (NVIDIA nForce2) Mainboard

The board is built on the same PCB as NF7-S, but it has weaker peripherals support. 


  • Package of the standard design; 
  • Documentation: user manual in 6 languages; 
  • Cables: 1 ATA66/100/133 and FDD; 
  • Bracket with 2 USB ports; 
  • Bracket for the rear computer panel; 
  • CD containing: 
    • drivers; 
    • user guides for NVIDIA based boards; 
    • Adobe Acrobat Reader; 
    • DirectX 8.1; 
    • system monitoring utility. 

The layout has typical drawbacks: audio-ins are in front of PCI and an inserted video card can make it difficult to handle memory modules and IDE cables. 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 5 capacitors of 3300 uF and 4 of 1200 uF. 

The following controllers are integrated: 

  • audio controller based on the chipset and Avance Logic ALC650 AC'97 codec; 5.1 audio system supported, front audio inputs/outputs and SPDIF connectors provided; 
  • network controller based on the chipset; 10BaseT/100BaseTX supported; 

Non-unsoldered connectors: SATA RAID controller with connectors, FireWire bus controller with connectors. 

System monitoring is supported by Winbond W83627HF-AW chip. What is controlled: 

  • processor voltages, 2.5, +3.3, +-5 and +-12 V, VBAT and +5 V Standby
  • speed of 3 fans; 
  • temperatures of the processor (built-in sensor) and the board (built-in sensor). 

There are 2 connectors for adjustable and 2 for unadjustable connection of fans (one of them is connected to a fan on the north bridge's heatsink). 

Brief board's characteristics: memory slots - 3 DDR SDRAM; expansion slots - AGP/ 5 PCI; I/O ports - 1 COM/ LPT/ 2 PS/2/ 6 USB 2.0; dimensions - 305x245 mm.

Changeable core voltage + 1.1-1.85 V in 0.025V steps
Changeable memory voltage + 2.4, 2.5, 2.6, 2.7 V
Changeable chipset voltage + 1.4, 1.5, 1.6, 1.7 V
Changeable AGP bus voltage + 1.5, 1.6, 1.7, 1.8 V
Changeable video core frequency + 100-123 MHz in 1MHz steps

We used the BIOS nf7_b15.b00 as the latest available version. 

The board has budget-level functionality, and we recommend it for the respective category of users and for those who don't need integrated features and are going to overclock their systems - in this respect ABIT NF7-M is far better that the competitors.
