System Memory
The boards have four DIMM sockets and support the following memory features:
•
2.5 V DDR SDRAM DIMMs with gold-plated contacts
•
Unbuffered, single-sided or double-sided DIMMs with the following restriction:
o
Double-sided
DIMMS
with x16 organisation are not supported.
•
4 GB maximum total system memory total amount of addressable memory.
•
Minimum total system memory: 128 MB
•
Non-ECC
DIMMs
•
Serial Presence Detect
•
DDR 333 MHz or DDR 400 MHz SDRAM DIMMs
Note:
•
Remove the PCI Express x16 video card before installing or upgrading memory
to avoid interference with the memory retention mechanism.
•
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. If
non-SPD memory is installed, the BIOS will attempt to correctly configure the
memory settings, but performance and reliability may be impacted or the DIMMs
may not function under the determined frequency.
The following table lists the supported DIMM configurations.
