System memory

System memory features
The board has eight DIMM sockets and supports the following memory features:

  • 1.35 V DDR3 SDRAM DIMMs (JEDEC Specification)
  • Four 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.
    • Double-sided 2400 MHz DIMMs are not supported.
  • 64 GB maximum total system memory (using 4 Gb memory technology).
  • Minimum total system memory: 1 GB using 512 MB x16 module
  • Non-ECC and ECC DIMMs
  • Serial Presence Detect
  • DDR3 2400 MHz, 2133 MHz, 1866 MHz, 1600 MHz, 1333 MHz, and 1066 MHz SDRAM DIMMs
  • XMP performance profile support for memory speeds above 1600 MHz
  • DIMM slots are numbered in installation order

For full compliance with all applicable DDR SDRAM memory specifications, the board must use 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.

1.5V is the recommended default setting for DDR3 memory voltage. The other memory voltage settings in the BIOS Setup program are provided for performance tuning purposes only.

Altering the memory voltage can:

  • Reduce system stability and the useful life of the system, memory, and processor.
  • Cause the processor and other system components to fail.
  • Cause reductions in system performance.
  • Cause heat or other damage.
  • Affect system data integrity.

Intel has not tested and does not provide a warranty for operation of the processor beyond its specifications. For information on the processor warranty, see the Processor Warranty Information.

Intel assumes no responsibility for memory installed on the desktop board, if used with altered clock frequencies and/or voltages. Check with the memory manufacturer for more information and warranty terms.
