Expansion Slots - Foxconn 945P7AA series User Manual

Expansion Slots

This motherboard includes three 32-bit Master PCI bus slots, two PCI Express
x1 slots, and one PCI Express x16 slot.
PCI Slots (Refer to Item 5 on motherboard layout in Chapter 1 for detailed
location)
The expansion card can be installed in the PCI slot. When you install or take out
such card, you must make sure that the power plug has been pulled out.
Please carefully read the instructions provided for such card, and install and set
the necessary hardware and software for such card, such as the jumper or
BIOS setup.
PCI Express Slots (Refer to Item 6&27 on motherboard layout in Chapter 1 for
detailed locations)
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 notable 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.
Note:
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.
