<ol>
<li>Remove write protection on CpuSetup EFI variable<br />
(GUID: B08F97FF-E6E8-4193-A997-5E9E9B0ADB32)<br />
to allow disabling CFG Lock at offset 0x43 for CPU undervolting.</li>
<li>Unlock advanced BIOS menu options if applicable<br />
(power limits, XMP, voltage settings, fan control, etc.)</li>
</ol>
<p dir="auto">CONFIRMED:</p>
<ul>
