PCI Express Slots
PCI Express will offer the following design advantages over the PCI and AGP
interface:
-Compatible with existing PCI drivers and software and Operating Systems.
-High Bandwidth per Pin. Low overhead. Low latency.
-PCI Express supports a raw bit-rate of 2.5 Gb/s on the data pins. This
results in a real bandwidth per pair of 250 MB/s.
-A point to point connection, allows each device to have a dedicated connec-
tion without sharing bandwidth.
-Ability to comprehend different data structure.
-Low power consumption and power management features.
PCI Express will take two forms, x16 and x1 PCI Express slots. Whereas the x16
slot is reserved for graphic/video cards, the x1 slots are designed to accommo-
date less bandwidth-intensive cards, such as a modem or LAN card.
The difference in bandwidth between the x16 and x1 slots are not able to be
sure, with the x16 slot pushing 4GB/sec (8GB/sec concurrent) of bandwidth,
and the x1 PCI Express slot offering 250 MB/sec.
Installing an expansion card
1. Before installing the expansion card, please make sure that the power sup-
ply is switched off or the power cord is unplugged. Please read the docu-
mentation that came with it and make the necessary hardware settings for
the card.
2. Remove the bracket facing the slot that you intend to use. Keep the screws
for later use.
3. Align the card connector with the slot and press firmly until the card is
completely seated on the slot.
4. Secure the card to the chassis with the screw you removed earlier.
If a performance graphics card was installed into x16 PCI
Express slot, 2X12 pin power supply was strongly recom-
mended since that card may be drawn 75W power.
