Product Description

1.5 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

• Dual channel interleaved mode support

Unbuffered, single-sided or double-sided DIMMs.

• 8 GB maximum total system memory. Refer to Section 2.1.1 on page 37 for

nformation on the total amount of addressable memory.

• Minimum recommended total system memory: 256 MB

• Non-ECC DIMMs

• Serial Presence Detect

• DDR3 1333 MHz, DDR3 1066 MHz, and DDR3 800 MHz SDRAM DIMMs

 NOTES

• Remove the video card in the Primary PCI Express x16 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.

Table 3 lists the supported DIMM configurations.
