Main Memory

✏
NOTE
To be fully compliant with all applicable Intel
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:
• Up to two 184-pin Double Data Rate (DDR) SDRAM Dual Inline Memory Modules (DIMMs)
with gold-plated contacts. Supported memory configuration are:
— DDR333: to run DDR333 memory at full speed requires an Intel Pentium 4 processor
with 533 MHz front side bus frequency (FSB). DDR333 memory will run only at
DDR266 speeds when using a processor with 400 MHz FSB.
— DDR266: requires an Intel Pentium 4 processor with 533/400 MHz FSB, or Intel
Celeron processor with 400 MHz FSB.
• Unbuffered and non-registered single or double-sided DIMMs
• Serial Presence Detect (SPD) memory only
• Non-ECC RAM (ECC memory will run in non-ECC mode)
• 2.5 V memory

NOTE
Desktop Board D845GERG2/D845GEBV2 has 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:
http://support.intel.com/support/motherboards/desktop/
All memory components and DIMMs used with the desktop boards must comply with the
PC SDRAM specifications. You can access these documents through the World Wide Web at:
