The AGP4X slot (1.5V) allows you to insert an AGP graphics card. AGP is an
interface specification designed for the throughput demands of 3D graphics.
It introduces a 66MHz, 32-bit channel for the graphics controller to directly
access main memory and provides 4X (1.07GB/s).
PCI Slots
The five PCI slots allow you to insert expansion cards to meet your needs.
When adding or removing PCI expansion cards, ensure that you unplug the
power supply first. Meanwhile, read the documentation for the expansion card
to make any necessary hardware or software settings for the expansion card,
such as jumpers, switches or BIOS configuration.
CNR (Communication Network Riser) Slot
The CNR slot allows you to insert a CNR expansion card. CNR is a specially
designed network, audio, or modem riser card for ATX family mainboards. Its
main processing is done through software and is controlled by the mainboard's
chipset.
