RAM
Computer memory, also known as random access memory (RAM), is installed
into two 200-pin SO-DIMM slots on the motherboard. Each slot supports a
PC2-5300 compliant, unbuffered DDR2 SDRAM module, up to 2 Gbyte in size.
The SDRAM modules will run at 667 MHz if the Intel Core 2 Duo T7500
processor is installed. The SDRAM modules will run at 533 MHz if the Intel
Celeron 550 processor is installed.
Display
Display capabilities are made possible due to the integrated Intel GME965
GMCH chip.
The GMCH chip can output to two display devices simultaneously. This is made
possible by two independent graphics controllers.
Graphics controllers
The Intel GME965 GMCH chip features two graphics controllers:
• A Serial Digital Video Out (SDVO) output. The SDVO output connects to the
video encoder, which allows you to connect a digital display device such as a digital
flat panel.
• A random access memory digital-to-analog converter (RAMDAC) output. The
300 MHz RAMDAC output generates analog signals to drive a high-resolution
analog display device.
The Intel GME965 GMCH chip uses up to 384 Mbytes of computer memory
to store display data.
Encoder
Matrox 4Sight X provides a video encoder driven by one of the graphics controllers
of the GME965 GMCH chip. This encoder uses transition minimized differential
signaling (TMDS) through the digital visual interface (DVI-D).
