Performance Acceleration Technology (PAT)
PAT mode is supported only when the system uses DDR400 with
800MHz FSB CPU. PAT performs data transactions directly from the
CPU to the system memor y, bypassing the normal path of
operation. This reduces the MCH timing therefore providing
improved system performance.
Expansion Slots
The system board is equipped with 1 AGP slot and 5 PCI slots.
AGP (Accelerated Graphics Port)
• Supports AGP 3.0 (AGP 4x and 8x) and AGP 2.0 (AGP 1x and
4x) spec.
• Supports 1.5V AGP 8x (2.13GB/sec.) and AGP 4x (1066MB/
sec.) add-in cards.
AGP is an interface designed to support high performance 3D
graphics cards for 3D graphics applications. It handles large
amounts of graphics data with the following features:
• Pipelined memory read and write operations that hide
• Demultiplexing of address and data on the bus for nearly
