64-bit / 133 MHz PCI-X Capable Subsystem
The 64-bit/133 MHz PCI segment includes one 3.3 V keyed PCI expansion slot that can support
PCI-X add-in cards up to 133 MHz and are backward compatible to 64 bit/66 MHz, 64 bit/33 MHz,
and 32 bit/33 MHz PCI cards.
64-bit/133 MHz PCI features include:
Bus speed up to 133 MHz
3.3 V signaling environment
Burst transfers up to a peak of 1000 megabytes per second (MB/s)
8-, 16-, 32-, 64-, or 100-bit data transfers
Plug and Play ready
Parity enabled
NOTE
The speed of the bus will run at the speed of the adapter installed.
64-bit / 100 MHz PCI-X Capable Subsystem
The 64-bit/100 MHz PCI segment includes two 3.3 V keyed PCI expansion slots that can support
add-in cards up to 100 MHz and are backward compatible to 64-bit/66 MHz, 64 bit/33 MHz, and
32 bit/33 MHz PCI cards.
64-bit/100 MHz PCI features include:
Bus speed up to 100 MHz
3.3 V signaling environment
Burst transfers up to a peak of 800 Megabytes per second (MB/s)
8-, 16-, 32-, or 64-bit data transfers
Plug and Play ready
Parity enabled
NOTE
If you install a slower card into one of the PCI 64/100 connectors, the bus
speed for both connectors will be lowered to the speed of the slowest adapter.
