All Sun Microsystems parts are known by at least two numbers, the X-Option number and the Part number. The best way to find out what part you have is the BarCode. Every part that Sun Microsystems sells has a Sun bar-code. This bar-code has both the part number and serial number of the part. (The X-Option number is not located on the part.) Here is a sample Sun Barcode:

An X-Option may have multiple part numbers and a part number may have multiple X-Option numbers associated with it.

Notes:

1. DIMMs are required on both the Riser Board and the System Board.

   (A third quad may be installed in either remaining bank, but that will disable interleaving.)
4. To activate 4-way interleaving, all four banks must be populated with quads.
5. Each bank addresses 1GB of memory.
