Difference being, there is nothing stopping me from trying - everything will just freeze.&lt;p&gt;It&amp;#x27;s fascinating - for something as simple as a bunch of LEDs, these companies must have spent millions of developer hours to produce such heaping piles of garbage - and OpenRGB proves all of them wrong.&lt;p&gt;[0] If anyone knows of a way to control at least the LED backlight on a Gigabyte Auorus XTREME 3080 (ideally the little LCD as well) - please let me know - OpenRGB can&amp;#x27;t do it. The Gigabyte software is so unbelievably broken that it doesn&amp;#x27;t even recognize the GPU, and I feel like I&amp;#x27;ve tried every workaround under the sun. I am unfortunately not very well versed in the Windows world.</text></comment>

Can you just send control information over the channels that data to be stored in memory also uses to get into the module? Does it mean that you need to install drivers for them? What happens if you do not?&lt;p&gt;Update: DDR4 modules seem to have pins for a built-in SMB&amp;#x2F;I2C bus. Maybe this is used for controlling the LEDs. &amp;#x2F;&amp;#x2F; It looks like it:&lt;p&gt;&lt;a href=&quot;https:&amp;#x2F;&amp;#x2F;www.reddit.com&amp;#x2F;r&amp;#x2F;hardware&amp;#x2F;comments&amp;#x2F;aiwrt2&amp;#x2F;how_does_rgb_led_control_work_for_dram&amp;#x2F;&quot; rel=&quot;nofollow&quot;&gt;https:&amp;#x2F;&amp;#x2F;www.reddit.com&amp;#x2F;r&amp;#x2F;hardware&amp;#x2F;comments&amp;#x2F;aiwrt2&amp;#x2F;how_does_r...&lt;/a&gt;&lt;p&gt;&lt;a href=&quot;https:&amp;#x2F;&amp;#x2F;gitlab.com&amp;#x2F;CalcProgrammer1&amp;#x2F;KeyboardVisualizer&amp;#x2F;-&amp;#x2F;issues&amp;#x2F;85#note_76665251&quot; rel=&quot;nofollow&quot;&gt;https:&amp;#x2F;&amp;#x2F;gitlab.com&amp;#x2F;CalcProgrammer1&amp;#x2F;KeyboardVisualizer&amp;#x2F;-&amp;#x2F;issu...&lt;/a&gt;</text></comment>
