System Memory for Intel® Desktop Board DQ77CP

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)
• Two independent memory channels with interleaved mode support
• Unbuffered, single-sided, or double-sided DIMMs with the following restriction: Does not support double-sided x16 DIMMs
• 32 GB maximum total system memory (with 4 Gb memory technology)
• 1 GB minimum recommended total system memory
• Non-ECC DIMMs
• Serial presence detect
• DDR3 1600 MHz, DDR3 1333 MHz, and DDR3 1066 MHz SDRAM DIMMs. Third-generation Intel® Core™ Processors are the only processor family that supports DDR3 1600 MHz DIMMs
• XMP version 1.3 performance profile support for memory speeds of 1600 MHz or lower

For full compliance with 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.
