FEATURES
The VX442HR is an audio card for PCI bus. It is‘Universal PCI 64-bit/66 MHz’
(PCI 2.2), which means it can be plugged in 32-bit/33 MHz 5 V PCI slots as
well as in 64-bit/66 MHz 3.3 V keyed PCI slots. The cards is also compatible
with PCI-X interfaces.
The VX442e is an audio card for PCI EXPRESS
TM
(PCIe
®
) bus. It is in PCI
EXPRESS
TM
x1 format and can thus be plugged into any PCIe
®
slot (x1, x2, x4,
x8, x16, x32).
