X570 Taichi Memory RGB Control: Getting It Working

We recently reviewed COLORFUL’s CVN Guardian DDR4-3200 on an ASRock X570 Taichi, and had a lot of trouble controlling the RGB. In fact, none of the RGB modules we tried worked with the X570 Taichi. Eventually we got it working, so here’s the fix we found.

The solution comes from the ASRock forums, posted by ASRock TSD. However, we’re adding a bit more information that should hopefully make it easier to follow. In addition, the forum thread was hard to find – the hope is this article won’t be.

These steps might also work for any other ASRock motherboard where memory RGB control isn’t working – there doesn’t seem to be anything specific to the X570 Taichi. However, it’s the X570 Taichi that ASRock TSD gave these steps for, and the Taichi we’ve used them on. We can’t guarantee what will happen on a different board.

Step 1: Get the Very Latest Version of ASRock Polychrome RGB Software

The biggest problem we ran into is finding the right software version to control memory RGB with the latest (3.61) X570 Taichi BIOS. Nothing less than version 2.0.83 will work. At time of writing ASRock APP shop delivers version 2.0.80. Even worse, the download page for the motherboard links to version 2.0.38 from 2019. The required version can be downloaded directly from ASRock at https://download.asrock.com/Utility/RGB/PolychromeRGB(v2.0.83).zip.

Before installing the latest version, make sure any previous version has been uninstalled. This means firstly, uninstalling the program through control panel. Secondly, to make sure it’s fully uninstalled, check in C:\Program Files (x86)\ASRock Utility\. If there’s a folder called ASRRGB in there, remove it. On the other hand, if the ASRRGB folder is gone or even the ASRock Utility folder itself doesn’t exist, you’re good.

After removing any old version, reboot. You can then install the latest version, linked above.

Step 2: Update the RGB Controller Firmware on the X570 Taichi

There’s more firmware on a modern motherboard than just the BIOS. ASRock have RGB controller chips on the X570 Taichi, and those have their own firmware. The latest firmware version is 3.4 at time of writing. If you’re on anything below that (or not sure), you’ll need to update.

You can check the firmware version in the ASRock Polychrome settings page – the versions shown here are the ones that work with BIOS 3.61 on the X570 Taichi

Updating the RGB controller firmware does require you to get a bit retro. Specifically, you need to use the command prompt – an old-school text-based interface. Don’t worry though, the steps are straightforward.

Firstly, because this is accessing low-level hardware, you need to run Command Prompt as administrator. To do this, search for “cmd” in the start menu. Making sure the program that comes up is Command Prompt, click on “Run as Administrator”.

Here’s what you should be seeing in the start menu when you’re running Command Prompt as administrator

Secondly, you need to change to the right folder. Command Prompt is a bit like File Explorer, in that it works in a certain folder. ASRock’s firmware update utility comes buried in the installation folder for Polychrome. To switch to that folder, use the following command:

cd “C:\Program Files (x86)\ASRock Utility\ASRRGBLED\Bin”

This is what you should be looking at after switching folder, and with the next command – WriteFW.bat – typed in ready to hit enter and run it

Finally, flashing the firmware. ASRock has provided a script that runs the firmware update. Once you’re in the folder as above, you can run it with:

WriteFW.bat

You might be wondering if you can just run the script from File Explorer, rather than messing around with Command Prompt. We wondered that too, but it didn’t seem to work. When run normally it doesn’t have the required permissions, and when run as administrator it seems to run in the wrong folder.

This is what you should be looking at after running WriteFW.bat and letting the script complete

Once the firmware update is complete, everything should be good to go. Reboot once more, fire up ASRock Polychrome, and get back to enjoying your RGB RAM!
