System Memory for the Intel® Desktop Board DZ77GA-70K






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

  • 1.5V DDR3 SDRAM DIMMs with gold plated contacts, with the option to raise the voltage to support higher performance DDR3 SDRAM DIMMs
  • 1.35V Low Voltage DDR3 DIMMs (JEDEC specification)
  • Unbuffered, single-sided or double-sided DIMMs with the following restriction: Does not support double-sided x16 DIMMs
  • 32 GB maximum total system memory (using 4 Gb memory technology).
  • Minimum total system memory: 1 GB using 512 MB x16 module
  • Non-ECC DIMMs
  • Serial Presence Detect
  • Support for DDR3 1066 MHz to +2400 MHz DIMMs
  • DDR3 1600 MHz DIMMs are only supported by 3rd generation Intel Core processor family processors
  • XMP version 1.3 performance profile support for memory speeds above 1600 MHz

For full compliance with all applicable Intel SDRAM memory specifications, the board requires DIMMs supporting the Serial Presence Detect (SPD) data structure. Using DIMMs that support SPD, 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 tries to correctly configure the memory settings, but performance and reliability can be impacted. Also, the DIMMs might not function under the specified frequency.

1.5V is the recommended and default setting for DDR3 memory voltage. The other memory voltage settings in the BIOS Setup program are provided for performance tuning purposes only. Changing 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 the processor when it is used beyond its specifications. For information on the processor warranty, see Processor Warranty Information.

Intel assumes no responsibility that the memory installed on the desktop board, if used with altered clock frequencies and/or voltages, is fit for any particular purpose. Check with the memory manufacturer for warranty and specific details.
