  • Page 6 1.2.1. The 845D-AV Mainboard The 845D-AV mainboard is a Pentium™ 4 DDR platform. It supports a maxi- mum memory of 2GB and comes with 4 USB ports. Onboard it has six PCI slots and a 1x/2x/4x AGP slot (which only supports 1.5V AGP cards). The 845D-AV mainboard also comes with three fan connectors (for additional thermal protection) and three power supply connectors.
  • Page 7 DC power supply from +1.10V to +1.85V. System Memory The 845D-AV mainboard uses Double Data Rate Dual Inline Memory Modules (DDR DIMM). Each mainboard has two 184-pin DIMM sockets. These sockets support 2.5V (power level) single-sided or double sided PC1600 (DDR200) or PC2100(DDR266) DDR DIMM modules The maximum memory supported by these mainboards is 2 GB.
  • Page 8 USB Ports USB allows data exchange between your computer and a wide range of simultaneously accessible external Plug and Play peripherals. The 845D-AV mainboard is equipped with four USB connectors. USB 1 and USB 2 are external connectors. They can be found on the PC 99 ATX connector. The other USB connectors are internal connectors and can be used to connect other USB devices.
  • Page 9 1.4.1. Hardware Monitoring System Utility The 845D-AV mainboard comes with the Hardware Monitoring System utility contained on the CD. It is capable of monitoring the systems hardware conditions such as the temperature of the processor, voltage, and the speed of both the CPU and chassis fans.
