1.4 System Memory
The board has two 204-pin SO-DIMM sockets and supports the following memory features:
• 1.35 V DDR3L 1600/1866 MHz SDRAM non-ECC SO-DIMM with gold plated contacts on
Intel Celeron processor J3455
• Two memory channels
• Unbuffered, single-sided or double-sided SO-DIMMs using 4 Gb or 8 Gb technology
(density)
• 8 GB maximum total system memory (with 4 Gb or 8 Gb memory technology). Refer to
Section 2.1.1 on page 37 for information on the total amount of addressable memory.
• Minimum recommended total system memory: 2048 MB
• Serial Presence Detect
• Optional 2 GB DDR3L 1600 MHz SO-DIMM pre-installed (included in Intel NUC Kit
NUC6CAYS only)
NOTE
To be fully compliant with all applicable DDR SDRAM memory specifications, the board should
be populated with SO-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 SO-DIMMs may not function under the determined frequency.
NOTE
Intel NUC Board NUC6CAYB supports only 4 Gb and 8 Gb memory technologies (also referred
to as “SDRAM density”). Table 4 lists the supported SO-DIMM configurations. Table 5
lists the
SO-DIMM configurations that are not supported.
