Accelerated Graphics Port (AGP or A.G.P.)
Typically, 3D graphics rendering requires a tremendous amount of memory, and
demands ever increasing throughput speed as well. As 3D products for the
personal computer become more and more popular, these demands will only
increase. This will cause a rise in costs for both end users and manufacturers.
Lowering these costs as well as improving performance is the primary motivation
behind AGP. By providing a massive increase in the bandwidth available between
the video card and the processor, it will assist in relieving some of these pressures
for quite sometime.
The board provides the AGP 2.0 interface. The AGP Interface Specification
revision 2.0 enhances the functionality of the original AGP Interface Specifica-
tion (revision 1.0) by allowing 4X data transfers (4 data samples per clock) and
1.5 volt (power supply) operation. The AGP 2.0 interface, along with SDRAM
memory technology, allows graphics controllers to access main memory at over
1GB/s. In order to match the 4X AGP Card. The board used the Universal AGP
connector. (1.5 volt AGP Card supports only).
Ultra ATA/66/100
The ICH4 provides two channel Ultra ATA/66/100 Bus Master IDE controllers, that
support Ultra ATA/66/100 protocols, perfect for such demanding applications as
real-time video, multimedia, and high performance operating system. A new IDE
cable is required for Ultra ATA/66/100. This cable is an 80 conductor cable;
however the connectors are, of course, backwards compatible with ATA/33.
Hardware Monitoring
Hardware monitoring allows you to monitor various aspects of your systems
operations and status. The features include CPU temperature, voltage and RPM of
fan.
