AGP
The AGP PRO connector supports the following:
•
4x, 8x AGP 3.0 add-in cards with 0.8 V I/O.
•
1x, 4x AGP 2.0 add-in cards with 1.5 V I/O.
•
AGP PRO add-in cards with the above characteristics.
AGP is a high-performance interface for graphics-intensive applications, such as 3D applications. While
based on the
PCI Local Bus Specification , Rev. 2.2, AGP is independent of the PCI bus and is intended for
exclusive use with graphical display devices. AGP overcomes certain limitations of the PCI bus related to
handling large amounts of graphics data with the following features:
•
Pipelined memory read and write operations that hide memory access latency.
•
Demultiplexing of address and data on the bus for nearly 100 percent efficiency.
NOTES
•
AGP 2x operation is not supported.
•
Install memory in the DIMM sockets prior to installing the AGP video card to avoid interference
with the memory retention mechanism.
•
The AGP connector is keyed for Universal 0.8 V AGP 3.0 cards or 1.5 V AGP 2.0 cards only.
•
Do not attempt to install a legacy 3.3 V AGP card. The AGP connector is not mechanically
compatible with legacy 3.3 V AGP cards.
