Recommended minimum system requirements

Clear Linux* OS can run on most modern hardware and is capable of running with modest hardware resources. Out of the box, Clear Linux OS can run on a single CPU core, 1 GB RAM, and minimum of disk space of:

• 4 GB for the live server

• 20 GB for the live desktop

Caution

Advanced users who wish to install on a disk using less than the recommended space requirements may use the flag --skip-validation-size. Use of this flag may cause the installation to fail due to inadequate disk space.

For use cases requiring minimal resources, Clear Linux OS about can be used to create a highly customized installation that can even run on a system with a 128MB of memory and 600MB of disk space, for example.

Installer requirements

The live desktop installer requires at least 1 GB of RAM because more resources are required to run in live mode than after Clear Linux OS is installed onto persistent storage.

For hardware with less resources, use the live server installer because it has a smaller memory footprint.

See https://clearlinux.org/downloads for more download options.

System requirements

Clear Linux OS requires an x86 64-bit processor which supports Intel® Streaming SIMD Extensions 4.2 (Intel® SSE 4.2).

For information on the boot loader, see the clr-boot-manager readme .

The Clear Linux OS installer performs a system compatibility check upon booting. To manually verify system compatibility with Clear Linux OS, run the compatibility check tool or go to http://ark.intel.com and check for these features:

• Instruction Set:

  • 64-bit

• Instruction Set Extensions:

  • Supplemental Streaming SIMD Extension 3 (SSSE3)

  • Intel® Streaming SIMD Extensions 4.1 (Intel® SSE 4.1)

  • Intel® Streaming SIMD Extensions 4.2 (Intel® SSE 4.2)

  • Carry-less Multiplication (PCLMUL)

The following processor families have been verified to run Clear Linux OS:

• Intel® Core™ processor family (2nd generation or greater)

• Intel® Xeon® E3-xxxx processor

• Intel® Xeon® E5-xxxx processor

• Intel® Xeon® E7-xxxx processor

• Intel Atom® processor C Series

• Intel Atom® processor E Series
