Intel Desktop Boards D865GRH Product Guide

Main Memory

NOTE

To be fully compliant with all applicable Intel® SDRAM memory specification addendums, 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 board supports system memory as defined below:

•Dual channel and up to four 184-pin Double Data Rate (DDR) SDRAM Dual Inline Memory Module (DIMMs) connectors with gold-plated contacts.

•Supported memory configurations are:

		Front Side Bus	Memory Speed
Memory Speed	Processor	Frequency	Outcome
DDR400	Pentium 4 processor	800 MHz	400 MHz
DDR333	Pentium 4 processor	800 MHz	320 MHz
	Pentium 4 processor	533 MHz	333 MHz
	Pentium 4 processor or	400 MHz	266 MHz
	Celeron processor
DDR266	Pentium 4 processor	533 MHz or 400 MHz	266 MHz
	Celeron processor	400 MHz	266 MHz

•Support for:

Unbuffered, non-registered DIMMs

Serial Presence Detect (SPD) memory only

Support for Suspend to RAM (STR), S3 ACPI state

Non-ECC DDR

2.5 V memory

NOTE

System resources (such as PCI and AGP) require physical memory address locations that reduce available memory addresses above 3 GB. This may result in less than 4 GB of memory being available to the operating system and applications.
