Hardware Requirements
To avoid integration difficulties and possible board damage, your system must meet the
requirements outlined below. For a list of qualified components see the links under
http://www.support.intel.com/support/motherboards/server/SE7221BK1-E .
Processor
One 2.8 GHz or greater Intel® Pentium® 4 processor in an LGA775 package for an 800 MHz
system bus. For a complete list of supported processors, see the links under
http://www.support.intel.com/support/motherboards/server/SE7221BK1-E .
Memory
One to four DIMMs
Unbuffered DDR2 400/533 MHz
ECC or non-ECC (ECC will be disabled if any non-ECC DIMMs are used)
256MB to 1GB DIMMs
Should support Serial Presence Detect (SPD) data structure. This allows the BIOS to read the SPD
data and program the chipset to accurately configure memory settings for optimum performance. If
non-SPD memory is installed, the BIOS will attempt to correctly configure the memory settings,
but performance and reliability may be impacted or the DIMMs may not function under the
determined frequency.
For a complete list of supported memory DIMMs, see the links under
http://support.intel.com/support/motherboards/server/SE7221BK1-E .
