1.5 System Memory
The board has six DIMM sockets and supports the following memory features:
• 1.5 V, 1.3 V, and 1.25 V DDR3 SDRAM DIMMs
• Three 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.
• 24 GB maximum total system memory. Refer to Section 2.1.1 on page 39 for
i
nformation on the total amount of addressable memory.
• Minimum total system memory: 1 GB
• ECC and non-ECC DIMMs
• Serial Presence Detect
• DDR3 2400 MHz, 2133 MHz, 1866 MHz, 1600 MHz, 1333 MHz, and 1066 MHz
SDRAM DIMMs
• XMP version 1.2 performance profile support for memory speeds above 1600 MHz
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.
