NOTE:

Multicore is designed to improve performance of certain software products. Not all customers or software applications necessarily benefit from use of this technology. 64-bit computing system required. Performance and clock frequency vary depending on application workload and hardware and software configurations. Intel numbering is not a measurement of higher performance.

Intel Optane memory system acceleration does not replace or increase the DRAM in the system.

Intel Turbo Boost technology requires a PC with a processor with Intel Turbo Boost capability. Intel Turbo Boost performance varies depending on hardware, software, and overall system configuration.

Some functionality of vPro technology, such as Intel Active management technology and Intel Virtualization technology, requires additional 3rd-party software in order to run. Availability of future “virtual appliances” applications for Intel vPro technology is dependent on 3rd-party software providers. Compatibility of this generation of Intel vPro technology-based hardware with future “virtual appliances” is yet to be determined.

Memory

Specification	Description
DDR4-2666	Maximum: 32 GB Number of slots: (2) SODIMM (both slots are customer accessible/upgradeable) Up to 2666 MT/s
Configurations	4 GB total system memory (4 GB x 1) 8 GB total system memory (4 GB x 2) 8 GB total system memory (8 GB x 1) 16 GB total system memory (8 GB x 2) 16 GB total system memory (16 GB x 1) 32 GB total system memory (16 GB x 2)

NOTE:

Addressing memory above 4 GB requires a 64-bit operating system. With Windows 32-bit operating systems, the amount of usable memory is dependent upon the configuration, therefore above 3 GB, all memory might not be available due to system resource requirements.

Memory modules support data transfer rates up to 2666 MT/s; actual data rate is determined by the system configured processor. See processor specifications for supported memory data rate.

All memory slots are customer accessible/upgradeable.
