System Memory Features
The boards have four DIMM sockets and support the following memory features:
- 2.6 V (only) DDR 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: 128 MB
- Non-ECC DIMMs
- Serial Presence Detect
- DDR 400 MHz and DDR 333 MHz SDRAM DIMMs
Notes
- Remove the PCI Express x16 video card before installing or upgrading memory to avoid interference with the memory retention mechanism.
- 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 System Bus Frequency and Memory Speed Combinations
| To use this type of DIMM... |
The processor's system bus frequency must be... |
| DDR 400 |
800 MHz |
| DDR 333(Note) |
800 or 533 MHz | | Note: When using an 800 MHz system bus frequency processor, DDR 333 memory is clocked at 320 MHz. This minimizes system latencies to optimize system throughput.
