System Memory Features
The Intel® Desktop Board D845GERG2 has two DIMM sockets and support the following memory features:
- 2.5 V (only) 184-pin DDR SDRAM DIMMs with gold-plated contacts
- Unbuffered, unregistered single-sided or double-sided DIMMs
- Maximum total system memory: 2 GB; minimum total system memory: 64 MB
- DDR333/266 MHz DDR SDRAM DIMMs only
- Serial presence detect (SPD)
- Suspend to RAM
| Caution |
Do not use ECC DIMMs with these Desktop Boards. Using ECC DIMMs could damage the desktop board. | |
Integrator's Notes:
- Registered DIMMs are not supported.
- Double-sided x16 DIMMs are not supported.
- Remove the AGP video card before installing or upgrading memory to avoid interference with the memory retention mechanibodycopy.
- The desktop board has been designed to support DIMMs based on 512 Mbit technology for a maximum onboard capacity of up to 2 GB, but this technology has not been validated (currently validated up to 1.0 GB) on this board. Please refer to the latest lists of tested memory.
| 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. | |
