PCI Expansion


The SGI320 has three PCI card option slots on two PCI buses, one half-length 32-bit-wide slot on bus(0) and two full-length 64-bit-wide slots on bus(1). For optimum performance, cards should be installed in bus(1) slots first.

Although three cards generally offer ample expansion considering how much functionality is already built into the workstation, the problem arises with the 320’s lack of support for the widely available 5.0-volt PCI cards, instead supporting the newer but harder-to-find 3.3-volt PCI cards.

Below is a list of compatible PCI cards that have either been reported as working on the 320 or are designated as 3.3 volt cards. If you would like to report a particular card as functional on the 320, or alternatively use a PCI card not listed below, then please use the contact section to report it.

For information on the differences between 3.3V, 5V and Universal PCI cards, visit this link.
