Intel Desktop Boards D845EPT2 and D845EBG2 Product Guide

Main Memory

NOTE

To be fully compliant with all applicable Intel® SDRAM memory specifications, the board should be populated with DIMMs that support the Serial Presence Detect (SPD) data structure. If your memory modules do not support SPD, you will see a notification to this effect on the screen at power up. The BIOS will attempt to configure the memory controller for normal operation.

The Desktop Boards D845EPT2 and D845EBG2 support system memory as defined below:

Up to two 184-pin DDR SDRAM Dual Inline Memory Modules (DIMMs) with gold-plated contacts

DDR266 and DDR200 SDRAM

Unbuffered and non-registered single or double-sided DIMMs

Serial Presence Detect (SPD) memory

Non-ECC and ECC DIMMs

2.5 V memory only

64 Mbit, 128 Mbit, 256 Mbit, and 512 Mbit technologies for the following memory configurations:

64 MB (minimum)

256 MB (64 Mbit technology)

512 MB (128 Mbit technology)

1024 MB (256 Mbit technology)

2048 MB (512 Mbit technology)

NOTE

The Desktop Boards D845EPT2 and D845EBG2 have been designed to support DIMMs based on 512 Mbit technology up to 2 GB, but this technology has not been validated on these Intel desktop boards. For more information about the latest list of tested memory, refer to the Intel World Wide Web site at:
