System Memory Features
The board has two 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.
- 4 GB maximum total system memory
- Minimum total system memory: 512 MB
- Non-ECC DIMMs
- Serial Presence Detect
- DDR2 667 or DDR2 533 MHz SDRAM DIMMs
| 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 enables 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. | |

| Note |
Regardless of the DIMM type used, the memory frequency will either be equal to or less than the processor system bus frequency. For example, if DDR2 800 memory is used with a 533 MHz system bus frequency processor, the memory will operate at 533 MHz. The table below lists the resulting operating memory frequencies based on the combination of DIMMs and processors. | |
