Specification Update for the Intel® Desktop Board DG45ID This document is an update to the specifications contained in the Intel® Desktop Board DG45ID Technical Product Specification (Order Number E35960). It is intended for hardware system manufacturers and software developers of applications, operating systems, or tools. It will contain Specification Changes, Errata, Specification Clarifications, and Documentation Changes.
Terminology Specification Changes are modifications to the current published specifications. These changes will be incorporated in the next release of the specifications. Errata are design defects or errors. Characterized errata may cause the desktop board behavior to deviate from published specifications.
Summary Table of Changes The following table indicates the Specification Changes, Errata, Specification Clarifications, or Documentation Changes that apply to the Intel® Desktop Board DG45ID. Intel intends to fix some of the errata in a future revision of the desktop board, and to account for the other outstanding issues through documentation or specification changes as noted. This table uses the following notations: Codes Used in Summary Table Doc: Document change or update that will be implemented.
Specification Changes The Specification Changes listed in this section apply to the Intel® Desktop Board DG45ID Technical Product Specification (Order Number E35960). 1. Corrected the Jumper numbering in Figure 14 of Section 2.3 Jumper Block. Figure 14. Location of the Jumper Block 2. The following Caution statement was modified in the Technical Product Specification in Section 2.6 Thermal Considerations.
2.6 Thermal Considerations CAUTION A chassis with a maximum internal ambient temperature of 38 oC at the processor fan inlet is a requirement. Intel recommends the use of a Thermally Advantaged Chassis (TAC) for this desktop board. Use a processor heat sink that provides omni-directional airflow to maintain required airflow across the processor voltage regulator area. For a list of Thermally Advantaged Chassis (TAC) please refer to the following website: http://www.intel.com/go/chassis 3.

Tcontrol Values for Components Component Tcontrol Processor For processor Tcontrol, see processor datasheets and processor specification updates Intel G45 Express Chipset 99 oC Intel 82801JIR (ICH10R) 101 oC For more information regarding Thermal Design Guidelines please refer to: http://developer.intel.com/Products/Desktop/Chipsets/G45/G45technicaldocuments.htm 4. Support for up to 8 GB system memory has been changed to support for up to 16 GB system memory.
1.5 System Memory The board has four DIMM sockets and support the following memory features: • • • 1.8 V DDR2 SDRAM DIMMs with gold plated contacts, with the option to raise the voltage to support higher performance DDR2 SDRAM DIMMs Dual channel interleaved mode support Unbuffered, single-sided or double-sided DIMMs with the following restriction: Double-sided DIMMs with x16 organization are not supported.
2.1.1 Addressable Memory The board utilizes 16 GB of addressable system memory. Typically the address space that is allocated for PCI Conventional bus add-in cards, PCI Express configuration space, BIOS (SPI Flash), and chipset overhead resides above the top of DRAM (total system memory). On a system that has 16 GB of system memory installed, it is not possible to use all of the installed memory due to system address space being allocated for other system critical functions.
The amount of installed memory that can be used will vary based on add-in cards, BIOS settings, and operating system installed. Figure 8 shows a schematic of the system memory map. All installed system memory can be used when there is no overlap of system addresses. Figure 8.
Table 10 lists the system memory map. Table 10. System Memory Map Address Range (decimal) Address Range (hex) Size Description 1024 K - 16777216 K 16382 MB Extended memory 100000 - 3FFFFFFFF 960 K - 1024 K F0000 - FFFFF 64 KB Runtime BIOS 896 K - 960 K E0000 - EFFFF 64 KB Reserved 800 K - 896 K C8000 - DFFFF 96 KB Potential available high DOS memory (open to the PCI Conventional bus). Dependent on video adapter used.
