System Memory Features
The board has four DIMM sockets and supports 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.
• 8 GB maximum total system memory using DDR2 667 or DDR2 800 DIMMs
• Minimum total system memory: 512 MB
• Non-ECC DIMMs
• Serial Presence Detect
• DDR2 800 or DDR2 667 MHz SDRAM DIMMs
• DDR2 667 SIMMs with SPD timings of only 5-5-5 (tCL-tRCD-tRP)
• DDR2 800 SIMMs with SPD timings of only 5-5-5 or 6-6-6 (tCL-tRCD-tRP)

Note
A minimum of 512 MB of system memory is required to fully enable both the onboard graphics and the manageability engine.

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.

Supported DIMM Configurations
The following table lists the supported DIMM configurations:

Tested Memory

3rd Party Tested Memory*
3rd party tested memory occurs as requested by the memory vendors and is tested at an independent memory house that is not a part of Intel - Computer Memory Test Labs (CMTL).

Vendor Self Tested Memory
Intel supplies the memory vendors that participate in this program with a common memory test plan to use as a basic checkout of the memory stability. Memory listed here was either tested by the memory vendor or by Intel using this test plan. These part numbers may not be readily available throughout the product life cycle.

The table below lists parts which passed testing conducted using Intel's Self Test program for Intel® Desktop Board DG33TL. For a complete explanation of the self test see the Desktop Board Component Functional Testing Levels page.
