Intel SE7500CW2 manual Memory, PCI I/O Subsystem

Memory

The Server Board SE7500CW2 contains four 184-pin DIMM sockets and provides up to 4 GB of memory. Memory is partitioned as two banks of DDR DIMMs, each of which provides 144 bits of two-way interleaved memory.

The Server Board SE7500CW2 supports up to four ECC DDR DIMMs that are compliant with the JEDEC DDR 200/266 specification. A wide range of DIMM sizes are supported, including the following:

•128 MB

•256 MB

•512 MB

•1 GB

The minimum supported memory configuration is 256 MB, using two 128 MB DIMMs. The maximum configurable memory size is 4 GB using four 1 GB DIMMs.

✏NOTE

The Server Board SE7500CW2 has been designed to support up to 8 GB of memory using 2 GB DIMMs. To date, Intel has not been able to complete validation testing of 2 GB DIMMs and these parts are not supported. Check the following Web site for updates on supported memory:

http://www.intel.com/support/motherboards/server/SE7500CW2/ tested_memory.htm

DIMMs must be installed in pairs and must be populated starting with DIMM 1A and 1B (see Figure 22 on page 66 for the locations of the DIMM connectors). Although the Server Board SE7500CW2 architecture allows the user to mix various sizes of DIMMs between banks, DIMMs must be identical within the banks.

PCI I/O Subsystem

The Server Board SE7500CW2 provides three PCI bus segments in the form of one

PCI-X 133 MHz, two PCI-X 100 MHz, and two 32-bit /33 MHz slots over the three bus segments.
