Dear ASROCK,
the only way to fix my RGB problem is to reflash firmware. Good tips!!]]> Fri, 29 May 2020 14:52:40 +0000 https://forum.asrock.com/forum_posts.asp?TID=14497&PID=75964&title=cannot-control-addr-led-b450m-steel-legend#75964 https://forum.asrock.com/forum_posts.asp?TID=14497&PID=75874&title=cannot-control-addr-led-b450m-steel-legend#75874 Author: ASRock_TSD

Dear jokeUsa,

Greetings, this is ASRock TSD.


Regarding to this case, we provide some suggestions for verifying:

A.
1. Uninstall the Polychrome Utility from control panel > Program and then restart the system.
2. After booting into OS, please install the following Polychrome ver.2.0.66
https://www.asrock.com/MB/AMD/B450M%20Steel%20Legend/index.asp#Download

B.
Please refer to the following steps to flash LED firmware manually.
1. Open CMD as an administrator (type "CMD" in search bar right click & choose "Run as administrator" from the context menu)
2. Go to RGB app installation folder by typing "cd C:\Program Files (x86)\ASRock Utility\ASRRGBLED\Bin\"
3. Flash the RGB chip using the following command "wICPFLASHADSBv2.exe /File=nu51_3.04" //this will take around 30 seconds to flash the LED FW.

If the problem still persists, please clean install a fresh Windows 10 OS or use other addressable LED devices to verify.


Thanks!

All the best,
ASRock TSD

I mount a addressable 5V RGB LED strip on this board.
But the first 5 LED color are different the others so that I cannot control the RGB color.
No matter which RGB mode, the first 5 LED always get different than the remaining.
I have already used ASROCK polychrome tool but fail under win10.

Please advise, thank you.
