<p>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:</p>
<ul class="simple">
<li><p>4 GB for the <em>live server</em></p></li>
<li><p>20 GB for the <em>live desktop</em></p></li>
</ul>
<div class="admonition caution">
<p class="admonition-title">Caution</p>
<p>Advanced users who wish to install on a disk using less than the recommended
space requirements may use the flag <code class="docutils literal notranslate"><span class="pre">--skip-validation-size</span></code>. Use of this
flag may cause the installation to fail due to inadequate disk space.</p>
</div>
<p>For use cases requiring minimal resources, Clear Linux OS <a class="reference internal" href="../about.html#about"><span class="std std-ref">about</span></a> 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.</p>
<section id="installer-requirements">
<h2>Installer requirements<a class="headerlink" href="#installer-requirements" title="Link to this heading"></a></h2>
<p>The <em>live desktop</em> 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.</p>
<p>For hardware with less resources, use the <em>live server</em> installer because it
has a smaller memory footprint.</p>
<p>See <a class="reference external" href="https://clearlinux.org/downloads">https://clearlinux.org/downloads</a> for more download options.</p>

<h2>System requirements<a class="headerlink" href="#id1" title="Link to this heading"></a></h2>
<p>Clear Linux OS requires an x86 64-bit processor which supports Intel® Streaming SIMD
Extensions 4.2 (Intel® SSE 4.2).</p>
<p>For information on the boot loader, see the <a class="reference external" href="https://github.com/clearlinux/clr-boot-manager">clr-boot-manager readme</a> .</p>
<p>The Clear Linux OS installer performs a system compatibility check upon booting. To
manually verify system compatibility with Clear Linux OS, run the <a class="reference internal" href="../get-started/compatibility-check.html#compatibility-check"><span class="std std-ref">compatibility
check tool</span></a> or go to <a class="reference external" href="http://ark.intel.com">http://ark.intel.com</a> and check for
these features:</p>
<ul class="simple">
<li><p>Instruction Set:</p>
<ul>
<li><p>64-bit</p></li>
</ul>
</li>
<li><p>Instruction Set Extensions:</p>
<ul>
<li><p>Supplemental Streaming SIMD Extension 3 (SSSE3)</p></li>
<li><p>Intel® Streaming SIMD Extensions 4.1 (Intel® SSE 4.1)</p></li>
<li><p>Intel® Streaming SIMD Extensions 4.2 (Intel® SSE 4.2)</p></li>
<li><p>Carry-less Multiplication (PCLMUL)</p></li>
</ul>
</li>
</ul>
<p>The following processor families have been verified to run Clear Linux OS:</p>
<ul class="simple">
<li><p>Intel® Core™ processor family (2nd generation or greater)</p></li>
<li><p>Intel® Xeon® E3-xxxx processor</p></li>
<li><p>Intel® Xeon® E5-xxxx processor</p></li>
<li><p>Intel® Xeon® E7-xxxx processor</p></li>
<li><p>Intel Atom® processor C Series</p></li>
<li><p>Intel Atom® processor E Series</p></li>
</ul>

<section id="recommended-configurations">
<h2>Recommended configurations<a class="headerlink" href="#recommended-configurations" title="Link to this heading"></a></h2>
