Gigabyte K8NNXP-940 motherboard on NVIDIA nForce3
Pro 150
|
The board has a comprehensive bundle and functionality – an excellent example of a top-end product.
The circuitry is usual – the number of sockets is not very comfortably located along the left border; audio connectors are located in front of PCI slots, IDE RAID sockets – behind them, while the overcrowded memory sockets prevents free access to them. The access to jumper can be problematic during the motherboard installation. The brief board description is provided on PCB. Available voltage is indicated by a yellow LED. Besides, another LED is lit when you try to install a +3.3V graphics card prohibited for this board. The tri-channel switching voltage regulator features 6 x 3300µf and 4 x 1500µf capacitors. The board also has a Gigabyte DPS socket for additional VRM module. There are also AGP (4 x 1000µf and some smaller capacitors) and memory (6 x 1000µf) voltage regulators.
The board has no unsoldered circuitry. Its size is 305x245mm (full ATX, 9-screw mount, firm fixation). ITE IT8712F-A chip is used to monitor:
- CPU, memory, +3.3V, +12V voltage;
- Rpm of 2 fans;
- CPU and motherboard temperatures (using corresponding sensors).
