Features
PCI Express is a high bandwidth I/O infrastructure
that possesses the ability to scale speeds by forming
multiple lanes. The system board currently supports
the physical layer of x1 and x16 lane widths. The x1 PCI Express
lane supports transfer rate of 2.5 Gigabytes (250MBbps) per sec-
ond. The PCI Express architecture also provides a high performance
graphics infrastructure by enhancing the capability of a x16 PCI Ex-
press lane to provide 4 Gigabytes per second transfer rate.
The Intel 915GM north bridge chip comes integrated
with Intel Graphics Media Accelerator 900. It supports
dual independent display using DVI-D and VGA inter-
faces. The devices connected to these interfaces can be
displayed simultaneously.
The DVI-D (Digital Visual Interface) port is used to
connect a device that supports DVI-D such as digital
LCD monitor. DVI is an interface that converts analog signals into
digital signals. Data is transmitted using the TMDS (Transition Mini-
mized Differential Signaling) protocol, providing a digital signal from
the PC’s graphics subsystem to the display.
CPU Overheat Protection has the capability of moni-
toring the CPU’s temperature during system boot up.
Once the CPU’s temperature exceeded the tempera-
ture limit pre-defined by the CPU, the system will automatically shut-
down. This preventive measure has been added to protect the CPU
from damage and insure a safe computing environment.
Double Data Rate SDRAM (DDR SDRAM) is a type of
SDRAM that doubles the data rate through reading and
writing at both the rising and falling edge of each clock.
This effectively doubles the speed of operation therefore
doubling the speed of data transfer.
