LGA775 processor socket supporting 800MHz FSB Intel® Pentium® 4 processor.
Processor host bus AGTL+ support circuitry.
Processor Family
Pentium® 4
Pentium® 4
Celeron® D
Note: The Pentium® 4 Processor Extreme Edition IS NOT supported for use with the
Intel® Server Board SE7221BK1-E.The board is designed to provide up to 120A of
processor current. Processors with higher current requirements are not supported. For a
complete list of all supported processors, please visit the Intel® Server Board
SE7221BK1-E support site located at the following URL:
http://support.intel.com/support/motherboards/server/sb/CS-012690.htm
In addition to the circuitry described above, the processor subsystem contains the following:
Reset configuration logic
Server management registers and sensors
3.1.5
Interrupts and APIC
Interrupt generation and notification to the processor is done by the APICs in the ICH6R using
messages on the front side bus.
3.2
Memory Subsystem
The baseboard supports up to four DIMM slots for a maximum memory capacity of 4 GB. The
DIMM organization is x72, which includes eight ECC check bits. The memory interface runs at
400/533MT/s. The memory controller supports memory scrubbing, single-bit error correction and
multiple-bit error detection and Intel® x4 SDDC support with x4 DIMMs. Memory can be
implemented with either single sided (one row) or double-sided (two row) DIMMs.
3.2.1.1
Memory DIMM Support
The board supports un-buffered (not registered) DDR2 400/533-compliant ECC or Non-ECC
DIMMs operating at 400/533MT/s. Only DIMMs tested and qualified by Intel or a designated
memory test vendor are supported on this board. A list of qualified DIMMs is available at
http://support.intel.com/support/motherboards/server/SE7221BK1E. Note that all DIMMs are
supported by design, but only fully qualified DIMMs will be supported on the board.
The minimum supported DIMM size is 256 MB. Therefore, the minimum main memory
configuration is 1 x 256 MB or 256 MB. The largest size DIMM supported is 2 GB however, the
maximum main memory configuration is 4 GB implemented by 4 x 1 GB or 2 x 2 GB DIMMs.
Only un-buffered DDR2 400/533 compliant, ECC x8 and Non-ECC x8 or x16 memory
DIMMs are supported
ECC single-bit errors (SBE) will be corrected and multiple-bit error (MBE) will be
detected.
Intel® Server Board SE7221BK1-E also supports Intel® x4 SDDC with x4 DIMMs.
