SE7500CW2 Server Board Technical Product Specification
Functional Architecture
7
Revision 1.40
3.1.2.1
Memory DIMM Support
The Intel Server Board SE7500CW2 supports DDR-200 compliant registered ECC DIMMs and
DDR-266 compliant ECC DIMMS operating at 200MT/s. Only DIMMs tested and qualified by Intel
or a designated memory test vendor are supported on the Intel Server Board SE7500CW2. A list
of qualified DIMMs will be made available. Note that all DIMMs are supported by design, but only
fully qualified DIMMs will be supported.
The minimum supported DIMM size is 128 MB. Therefore, the minimum main memory
configuration is 2 x 128 MB or 256 MB. The largest size DIMM supported is a 2GB
1
registered
DDR-200 or DDR-266 ECC DIMM based on 512-megabit technology.
•
Only registered DDR-200 or DDR-266 compliant, ECC, DDR memory 2will be
supported
•
ECC single-bit errors will be corrected and multiple-bit error will be detected.
Intel Server Board SE7500CW2 also supports chipkill feature with x4 DIMMs.
•
The maximum memory capacity is 8 GB
•
The minimum memory capacity is 256MB
3.1.2.2
Memory Configuration
Memory interface between the MCH and DIMMs is 144 bit wide. This requires that two DIMMs be
populated per bank in order for the system to operate. At least one bank has to be populated in
order for the system to boot. If additional banks have less than two DIMMs, the memory for that
bank(s) will not be available to the system.
There are two banks of DIMMs , labeled 1 and 2. Bank 1 contains DIMM locations 1A and 1B and
bank 2 contains 2A and 2B. DIMM socket identifiers are marked with silkscreen next to each
DIMM socket on the baseboard. Note that the sockets associated with any given bank are
located next to each other.
The baseboard’s signal integrity and cooling are optimized when memory banks are populated in
order. Therefore, bank one must be populated before bank two.
DIMM and memory configurations must adhere to the following::
•
DDR-200 or DDR-266 ECC, registered, DDR DIMM modules
•
DIMM organization: x72 ECC
•
Pin count: 184
•
DIMM capacity: 128 MB, 256 MB, 512 MB, 1 GB, and 2 GB DIMMs
•
Serial PD: JEDEC Rev 2.0
•
Voltage options: 2.5V (VDD/VDDQ)
1 As of the writing of this document, testing with 2GB DIMM modules was not complete and therefore not yet
supported. 2GB DIMM support would allow for up to 8GB of main memory on the SE7500CW2. For updates o n
support of 2GB DIMM modules, visit the SE7500CW2 support website at
