This model can be literally called "a mainboard based on the top chipset for those who are interested in nothing but the chipset". What concerns additional controllers, there is only a FireWire port and Ethernet, which is traditional for practically all modern mainboards. Though it's a Gigabit one – but don't you agree that a regular 10/100 controller would have been strange on a 925X mainboard. As for the rest, the mainboard looks a masterpiece of minimalism, especially among top solutions. Which theoretically must involve an appropriate price.
The PCB layout is standard – one should note an inconvenient placement of the audio-in jack and the density of memory slots. Access to jumpers is not hampered, when the mainboard is in a case, their brief descriptions are provided on the PCB. The 4-phase switching voltage regulator of the processor incorporates three 1800 uF capacitors and eight 560 uF capacitors. The PCB also contains voltage regulators for the PCI-E x16 bus (2x1000 uF) and for memory (4x1000 uF).
The PCB lacks the following elements, which seats are provided by the layout: WOM connector. Mainboard dimensions – 305x245 mm (full-sized ATX, ten-screw mount, all mainboard edges are firmly fixed). The ITE IT8712F-A chip is used to monitor:
- CPU and memory voltage, +3.3 +5 and +12 V
- RPM of 2 fans
- CPU temperature (by the embedded CPU sensor)
- Board temperature (by the on-board sensor)

We can note the SATA power converter (useful accessory for the owners of power units without Serial ATA power connectors) and Norton Internet Security 2004 – fairly good personal firewall (the latest version). Foxconn SuperUtilites is a set of utilities, which functionality can be easily guessed from their titles: SuperBoot, SuperBIOS-Protect, SuperStep (overclocking), SuperLogo, SuperUpdate.
Integrated Controllers
- Avance Logic ALC880 HD Audio Codec supporting 7.1 surround sound audio, with front line-in/out and S/PDIF jacks
- Network controller based on the Realtek RTL8110S-32 chip supporting 10Base-T/100Base-TX/1000Base-T
- FireWire based on the VIA VT6307 chip supporting two FireWire ports
The integrated audio quality was tested in 16bit, 44 kHz using the RightMark
