The Desktop Boards D845GEBV2 and D845GERG2 both have two DIMM sockets and support
the following memory features:
•
2.5 V (only) 184-pin DDR SDRAM DIMMs with gold-plated contacts
•
Unbuffered, unregistered single-sided or double-sided DIMMs
•
Maximum total system memory: 2 GB; minimum total system memory: 64 MB
•
DDR333/266 MHz SDRAM DIMMs only
•
Serial Presence Detect (SPD)
•
Suspend to RAM
CAUTION
Do not use ECC DIMMs with these Desktop Boards. Using ECC DIMMs could damage the
Desktop Board.

INTEGRATOR'S NOTES
•
Registered DIMMs are not supported.
•
Double-sided x16 DIMMs are not supported.
•
Remove the AGP video card before installing or upgrading memory to avoid interference
with the memory retention mechanism.
•
These Desktop Boards have been designed to support DIMMs based on 512 Mbit
technology for a maximum onboard capacity of up to 2 GB, but this technology has not
been validated (currently validated up to 1.0 GB) on this board. Please refer to the
following Intel web sites for the latest lists of tested memory:

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.
