Intel Desktop Board D946GZIS Specification Update

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.
