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:

In addition to the circuitry described above, the processor subsystem contains the following:

ƒReset configuration logic

ƒServer management registers and sensors

3.1.5Interrupts and APIC

Interrupt generation and notification to the processor is done by the APICs in the ICH6R using messages on the front side bus.

3.2Memory 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.

3.2.1.1Memory 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.

ƒOnly un-buffered DDR2 400/533 compliant, ECC x8 and Non-ECC x8 or x16 memory DIMMs are supported

ƒECC single-bit errors (SBE) will be corrected and multiple-bit error (MBE) will be detected.

ƒIntel® Server Board SE7221BK1-E also supports Intel® x4 SDDC with x4 DIMMs.
