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).
Intel® Internal Tested Memory
Intel's has a limited amount of memory tested for the desktop board. These part numbers may not be readily available throughout the product life cycle.
Intel Platform Memory Operations
Intel's Platform Memory Organization works closely with several validation labs to assure design validation testing is in place for the major RDRAM silicon manufacturers.
System Memory Features
The Intel® Desktop Board D865GRH has four DIMM sockets and support the following memory features:
- 2.6 V (only) 184-pin 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: 64 MB
- Non-ECC DIMMs
- Serial Presence Detect
- DDR400, DDR333, and DDR266 SDRAM DIMMs
The following table lists the supported system bus frequency and memory speed combinations.
|
To use this type of DIMM...
|
The processor's system bus frequency must be...
|
| DDR400 |
800 MHz |
| DDR333(Note) |
800 or 533 MHz |
| DDR266 |
800, 533, or 400 MHz |
|
Note: When using an 800 MHz system bus frequency processor, DDR333 memory is clocked at 320 MHz. This minimizes system latencies to optimize system throughput.
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 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.
The following table lists the supported DIMM configurations.
