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. Hardware and software
designed to be used with any given Altered Assembly (AA) and BIOS revision level
must assume that all errata documented for that AA and BIOS revision level are
present on all desktop boards.
Specification Clarifications describe a specification in greater detail or further
highlight a specification’s impact to a complex design situation. These clarifications
will be incorporated in the next release of the specifications.
Documentation Changes include typos, errors, or omissions from the current
published specifications. These changes will be incorporated in the next release of the
specifications.

Specification Changes
The Specification Changes listed in this section apply to the Intel® Desktop Board
D946GZIS Technical Product Specification (Order Number D56025). All Specification
Changes will be incorporated into a future version of that specification.
1. Change to Table 1, Section 1.1.1 Feature Summary
Table 1, Section 1.1.1, Feature Summary will change to remove support for DDR2
800 memory. The revised section of the table will change as follows:
Memory
• Two 240-pin DDR2 SDRAM Dual Inline Memory Module (DIMM)
sockets
• Support for DDR2 667, or DDR2 533 MHz DIMMs
• Support for up to 4 GB of system memory
2. Change to Section 1.4 System Memory
Section 1.4, System Memory will change to remove support for DDR2 800
memory. The revised section will change as follows:
1.4 System Memory
The board has two DIMM sockets and support the following memory features:
• 1.8 V (only) DDR2 SDRAM DIMMs with gold-plated contacts
• Unbuffered, single-sided or double-sided DIMMs with the following restriction:
Double-sided DIMMS with x16 organization are not supported.
• 4 GB maximum total system memory. Refer to Section 2.1.1 on page 43 for
information on the total amount of addressable memory.
• Minimum total system memory: 128 MB
• Non-ECC DIMMs
• Serial Presence Detect
• DDR2 667, or DDR2 533 MHz SDRAM DIMMs
NOTE
To be fully compliant with all applicable DDR SDRAM memory specifications,
the board should be populated with DIMMs that support the Serial Presence
Detect (SPD) data structure. This allows the BIOS to read the SPD data and
program the chipset to accurately configure memory settings for optimum
performance. If non-SPD memory is installed, the BIOS will attempt to
correctly configure the memory settings, but performance and reliability may
be impacted or the DIMMs may not function under the determined frequency.

Section 1.7.2 Audio Connectors:
INTEGRATOR’S NOTES
Electrostatic discharge (ESD) can damage desktop board components. Frontpanel connectors should provide sufficient protection to prevent ESD damage to
components inside the chassis enclosure.
