1.5
System Memory
The board has four DIMM sockets and supports the following memory features:
•
1.8 V DDR3 800 MHz, DDR3 1066 MHz, and DDR3 1333 (OC) MHz SDRAM DIMMs
•
Two independent memory channels with interleaved mode support
•
Unbuffered, single-sided or double-sided DIMMs with the following restriction:
Double-sided DIMMs with x16 organization are not supported.
•
8 GB maximum total system memory (with 2 Gb memory technology).
Refer to
Section 2.1.1 on page 39 for information on the total amount of addressable
memory.
•
Minimum total system memory:
512 MB
•
Non-ECC DIMMs
•
Serial Presence Detect
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.
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.
Table 4 lists the supported DIMM configurations.
