Server Board Features

NOTE

System resources (such as PCI and PCI Express*) require physical memory address locations that reduce available memory addresses above 3 GB. This may result in less than 4 GB of memory being available to the operating system and applications.

For a complete list of supported memory DIMMs, see the links under “Additional Information and Software.”

A minimum of 350 Watts is required. Your supply must provide a minimum of 1.2 A of 5 V standby current or the board will not boot.

NOTE

PCI Express* Card Electromechanical Specification Revision 1.0a, April 15, 2003 states, in part:

DOWNSHIFTING, WHICH IS DEFINED AS PLUGGING A PCI EXPRESS* CARD INTO A CONNECTOR THAT IS NOT FULLY ROUTED FOR ALL OF THE PCI EXPRESS* LANES, IN GENERAL IS NOT ALLOWED. THE EXCEPTION IS THE X8 CONNECTOR WHICH THE SYSTEM DESIGNER MAY CHOOSE TO ROUTE ONLY THE FIRST FOUR PCI EXPRESS* LANES. A X8 CARD FUNCTIONS AS A X4 CARD IN THIS SCENARIO.

The Intel Server Board SE7221BA1-E features two PCI Express* x4 connectors, each routed with a x1 lane and limited to x1 throughput.
