Memory testing has been performed under the following category:
Advanced Tested Memory*
Intel provides the Advanced environmental test procedures, test software and necessary hardware to an independent test lab to perform Advanced testing as requested by the memory vendors. Memory tested by Computer Memory Test Labs (CMTL).
System Memory Features
The Desktop Board D845PEBT2 has two DIMM sockets and supports 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 with the following restriction:
Double-sided DIMMsS with x16 organization are not supported
- 2 GB maximum total system memory with the following clarification:
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 on this Desktop Board. Please refer to the latest lists of tested memory.
- Minimum total system memory: 64 MB
- Non-ECC DIMMs
- Serial Presence Detect
- Suspend to RAM
- 333/266 MHz DDR SDRAM DIMMs
| Notes |
- Remove the AGP 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 Desktop 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.
