Intel® Server Board SE7520JR2 Functional Architecture Revision 1.0 C78844-002 29 Processor Family FSB Frequency Frequency Support Intel® Xeon™ 800 MHz 3.
Functional Architecture Intel® Server Board SE7520JR2 Revision 1.0 C78844-002 30 High and Low Ratio is determined and programmed to all processors. If there is no value that works for all installed processors, all processors not capable of speeds supported by the BSP are disabled and an error is displayed.
Intel® Server Board SE7520JR2 Functional Architecture Revision 1.0 C78844-002 31 BSP and starts executing from the reset vector (F000:FFF0h). A processor that does not perform the role of BSP is referred to as an application processor (AP).
Functional Architecture Intel® Server Board SE7520JR2 Revision 1.0 C78844-002 32 • Memory Controller Hub (MCH) • I/O Controller Hub (ICH5-R) • PCI-X Hub (PXH) The following sub-sections provide an overview of the primary functions and supported features of each chipset component as they are used on the Server Board SE7520JR2.
Intel® Server Board SE7520JR2 Functional Architecture Revision 1.0 C78844-002 33 GB/s. One x8 interface is used as the interconnect between the MCH and PXH, while the other is configured as two separate x4 interfaces to the full height riser slot. The E7520 MCH is a root class component as defined in the PCI Express Interface Specification, Rev 1.
Functional Architecture Intel® Server Board SE7520JR2 Revision 1.0 C78844-002 34 3.2.2.3 I/OxAPIC Controller The PXH contains two I/OxAPIC controllers, both of which reside on the primary bus.
Intel® Server Board SE7520JR2 Functional Architecture Revision 1.0 C78844-002 35 IDE channels of the ICH5R. One channel is accessed through the 40-pin connector on the baseboard.
Functional Architecture Intel® Server Board SE7520JR2 Revision 1.0 C78844-002 36 3.2.3.6 Advanced Programmable Interrupt Controller (APIC) In addition to the standard ISA-compatible PIC described in the previous section, the ICH5-R incorporates the Advanced Programmable Interrupt Controller (APIC).
Intel® Server Board SE7520JR2 Functional Architecture Revision 1.0 C78844-002 37 The ICH5-R supports slave functionality, including the Host Notify protocol.
Functional Architecture Intel® Server Board SE7520JR2 Revision 1.0 C78844-002 38 X8, double row 256MB 512MB 1GB 2GB X4, single row 256MB 512MB 1GB 2GB X4, Stacked, double row 512MB 1GB 2GB 4GB DIMMs on channel ‘A’ are paired with DIMMs on channel ‘B’ to configure 2-way interleaving.
Intel® Server Board SE7520JR2 Functional Architecture Revision 1.0 C78844-002 39 Using the following algorithm, BIOS configures the memory controller of the MCH to run in either dual channel mode or single channel mode: (1) If 1 or more fully populated DIMM banks are detected, the memory controller is set to dual channel mode.

Intel® Server Board SE7520JR2 Functional Architecture Revision 1.0 C78844-002 41 status of the extended memory test is displayed on the console. The status of base and extended memory tests are also displayed on an LCD control panel if present. The extended memory test is configured using the BIOS Setup Utility.
Functional Architecture Intel® Server Board SE7520JR2 Revision 1.0 C78844-002 42 Uncorrectable memory errors are critical errors that may cause the system to fail. The BIOS normally detects and logs these errors as IPMI SEL events for all management levels, except in the case described below.
Intel® Server Board SE7520JR2 Functional Architecture Revision 1.0 C78844-002 43 engine logs the failure. Both types of errors may be reported via multiple alternate mechanisms under configuration control.
Functional Architecture Intel® Server Board SE7520JR2 Revision 1.0 C78844-002 44 3.3.6.5 DIMM Sparing Function To provide a more fault tolerant system, the Intel E7520 MCH includes specialized hardware to support fail-over to a spare DIMM device in the event that a primary DIMM in use exceeds a specified threshold of runtime errors.
Intel® Server Board SE7520JR2 Functional Architecture Revision 1.0 C78844-002 45 3.3.6.6 Memory Mirroring The memory mirroring feature is fundamentally a way for hardware to maintain two copies of all data in the memory subsystem, such that a hardware failure or uncorrectable error is no longer fatal to the system.
