Revision 1.40
3. Functional Architecture
This chapter provides a high-level description of the functionality distributed between the
architectural blocks of the Intel Server Board SE7500CW2.
3.1 Processor and Memory Subsystem
The Intel
®
E7500 Chipset provides a 36-bit address, 64-bit data processor host bus interface,
operating at 400MHz in the AGTL+ signaling environment. The MCH component of the chipset
provides an integrated memory controller, an 8-bit Hub Interface, and three 16-bit hub interfaces.
The Hub Interface provides the interface to two 64-bit, 133/100/66/33-MHz, Rev 2.2 compliant
PCI-X bus via the P64H2. The Intel
®
Server Board SE7500CW2 directly supports up to 4GB
1
of
ECC memory, using four DDR-200 or DDR-266 compliant ECC DIMMs. The ECC
implementation in the MCH can detect and correct single-bit errors, and it can detect multiple-bit
errors, and supports ‘Chip Kill’ feature with DIMMs using x4 technology not x8.
3.1.1 Processor Support
The Intel
®
Server Board SE7500CW2supports one or two Intel
®
Xeon™ processors in the
Socket 604 FCPGA2 package.. When two processors are installed, all processors must be of
identical revision, core voltage, and bus/core speed. When only one processor is installed, it
should be in the socket labeled CPU1 and the other socket must be empty. The support circuitry
on the server board consists of the following:
Dual 604-pin processor sockets supporting 400 MHz FSB.
•
Processor host bus AGTL+ support circuitry.

Intel® Xeon™ FCPGA 2.4GHz 512KB Yes
Notes:
•
Processors must be populated in the sequential order. That is, processor socket #1
must be populated before processor socket #2.

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 on
support of 2GB DIMM modules, visit the SE7500CW2 support website at
