Tested Memory
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 D845EPI has two DIMM sockets and supports the following memory features:
- 2.5 V (only) 184-pin DDR SDRAM DIMMs with gold-plated contacts
- Unbuffered single-sided or double-sided DIMMs
- Maximum total system memory: 2 GB; minimum total system memory: 64 MB
- DDR333/266/200 MHz SDRAM DIMMs only
- Serial Presence Detect (SPD)
- Suspend to RAM
| If the processor's system bus frequency is. . . |
You can use this type of DIMM. . . |
| 533 MHz |
DDR333 or DDR266 |
| 400 MHz |
DDR266 or DDR200 | |
| Caution |
Do not use ECC DIMMs with this board. Using ECC DIMMs could damage the board. | |
Integrator's Notes:
- Registered DIMMs are not supported.
- Double-sided x16 DIMMs are not supported.
- If a full-length PCI add-in card is installed in PCI bus connector 1 (the PCI bus connector closest to the processor), remove the add-in card before installing or upgrading memory to avoid interference with the memory retention mechanism.
| 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. | |
The following table lists the supported DDR DIMM configurations.
