SE7221BK1-E Technical Product Specification

ƒThe maximum memory capacity is 4 GB

Note* Although the Intel® Server Board SE7221BK1-E supports a maximum memory capacity of 4 GB, system resources consume roughly 750 MB of physical memory in the maximum memory configuration. As a result, when 4 GB of memory is used, the amount of memory made available to the operating system is significantly lower than 4 GB; roughly 3200 MB. THIS IS ONLY AN ISSUE WHEN 4 GB OF MEMORY IS USED. A memory configuration of less than 4 GB will not be susceptible to this issue. Please refer to Intel® Technical Advisory TA 719-01on the support web site located at http://support.intel.com/support/motherboards/server/SE7221BK1E.

ƒThe minimum memory capacity is 256 MB via 1 x 256 MB DIMM module

3.2.1.2Memory Configuration

The memory interface between the GMCH and the DIMMs is 64-bit (non-ECC) or 72-bit (ECC) wide interface.

There are two banks of DIMMs, labeled 1 and 2. Bank 1 contains DIMM socket locations DIMM_1A and DIMM_2A. Bank 2 contains DIMM socket locations DIMM_1B and DIMM_2B. The sockets associated with each bank or “channel”, are located next to each other and the DIMM socket identifiers are marked on the baseboard silkscreen, near the DIMM socket. Bank 1 is associated with Memory Channel A while Bank 2 is associated with Memory Channel B. When only two DIMM modules are being used, the population order must be DIMM_1A, DIMM_1B to ensure dual channel operating mode.

To reiterate: In order to operate in Dual Channel Dynamic Paging Mode, the following conditions must be met:

2 identical DIMMs are installed, one each in DIMM_1A and DIMM_1B

4 identical DIMMs are installed (one in each socket location)

Installing only 3 DIMMs is not supported. Do not use DIMMs that are not “matched” (same type and speed). Use of identical memory parts is always the preferred method.

See Table 2 and Figure 2 on the following page for reference.

The system design is free to populate or not to populate any rank on either channel, including either degenerate single channel case.

DIMM and memory configurations must adhere to the following:

ƒDDR2 400/533 , un-buffered, DDR2 DIMM modules

ƒDIMM organization: x72 ECC or x 64 Non-ECC

ƒPin count: 240

ƒDIMM capacity: 256 MB, 512 MB, 1 GB DIMMs

ƒSerial PD: JEDEC Rev 2.0

ƒVoltage options: 1.8 V

ƒInterface: SSTL2
