Architecture
This chapter provides a high-level description of the functionality distributed between the
architectural blocks of the SE7501WV2 server board.
architectural blocks of the SE7501WV2 server board.
3.1 Processor and Memory Subsystem
The E7501 chipset provides a 36-bit address, 64-bit data processor host bus interface,
operating at 400MHz and 533Mz 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.
operating at 400MHz and 533Mz 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-MHz, Rev 1.0 compliant PCI-X
buses via the P64H2. The SE7501WV2 server board directly supports up to 12 GB of ECC
memory, using six DDR266 compliant registered ECC DIMMs. (Will support DDR200 modules
when 400MHz processors are installed.) The ECC implementation in the MCH can detect and
correct single-bit errors, detect multiple-bit errors, and support the Intel® Single Device Data
Correction features.

3.1.1 Processor
Support
The SE7501WV2 server board supports one or two Intel
®
Xeon™ processors in the Socket 604
INT3/FCPGA 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 CPU-1 and the other socket must be empty. The support circuitry on the
server board consists of the following:
revision, core voltage, and bus/core speed. When only one processor is installed, it should be in
the socket labeled CPU-1 and the other socket must be empty. The support circuitry on the
server board consists of the following:
•
Dual Socket 604 INT3/FCPGA CPU sockets supporting 533 MHz (will support 400 MHz
processors running at 400 Mhz speed.)
