1.4
System Memory
The board has four DIMM sockets and supports the following memory features:
•
1.5 V DDR3 SDRAM DIMMs with gold plated contacts, with the option to raise the
voltage to support higher performance DDR3 SDRAM DIMMs.
•
1.35 V Low Voltage DDR3 DIMMs (JEDEC specification)
•
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.
•
32 GB maximum total system memory (with 4 Gb memory technology).
Refer to
Section 2.1.1 on page 41 for information on the total amount of addressable
memory.
•
Minimum recommended total system memory:
1 GB
•
Non-ECC DIMMs
•
Serial Presence Detect
•
DDR3 1066 MHz to +2400 MHz SDRAM DIMMs
Note: JEDEC DDR3 1600 MHz DIMMs are only supported by 3
rd
generation Intel
Core processor family processors natively
•
XMP version 1.3 performance profile support for memory speeds up to +2400 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.
Table 3 lists the supported DIMM configurations.
