RGB LED Issues

I get a verification error when I try this. Any advice?

Project Name = AB350 Gaming-ITX/ac BIOS Version = P5.30 Reading file: nu51_1.10...0...ok. Enter ICP mode. Company ID: 0x000000FF, Device ID: 0x00FF00FF Erasing:     EEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEE Programming: PPPPPPPPPPPPPPPPPPPPPP Verifying:   Verify error: address=0x00000000, value: 0x000000FF != 0x00000002

How exactly you ran polychrome on your motherboard because i'm using the same board and i can only use asrock rgb led which is not exactly the same program. If I am right polychrome is not supported for my board but if I'm wrong and you know how to do it I will be glad if you help me and the others. Just to be known i tried your cmd commands and it won't work.

I am running latest polychrome and nu_2.08 on x470 board and it runs ok I cant controll header 2 at all and header 1 makes my EK vector always show blue no matter what i do.

I have:
- X370 Gaming K4 mobo
- bios v 5.30 with default bios settings
- Ryzen 1700X
- one RGB deepcool fan connected to 12vGRB cpu rgb header (not the amd usb header) and no other rgb device
- Windows 10 Pro, May 2019 update

- fresh install, pure stock drivers from Microsoft, except for Samsung NVME driver

- F-Stream Tuning utility ver:3.0.199
- ASRock RGB LED ver:1.0.41
- CPUID's cpu-z, hwmonitor, powermax
- hwinfo64
- AMD's Ryzen Master
- Samsung Magician

the RGB led utility cannot successfully run. Nothing appears. There is no change in the default breathing red led mode. In the task manager, I see the program start, then terminates after a couple of seconds.

I did not try the workaround others posted about using the programs's flash utility to flash the rgb chip since my issue is where the proram does not even start.

Hi!
I have an Asrock B450m Pro4 motherboard and bought a cheap LED strip (addressable RGB, WS2812B, with 60 LED-s on the strip).
The ASRock Polychrome software works just fine (1.0.48, firmware v2.9), but on the ARGB strip (plugged in the ARGB header on the motherboard) works just like a normal RGB strip, all LED-s showing the same color at the same intensity at once. I can change the color in the software, but just for the whole strip, not for the individual LED-s. Should'nt i be able to control the individual LED-s in the strip? The same strip works with my friends Arduino controller just as intended, all LED-s addressed individually.
Also, the colors in the software are messed up, for example when i set it to blue, the strip changes to a light pink, the all red shows as an almost white, faint blue. The LED count in the software shows 67 instead of 60, when i set it to 66 the last LED turns off, by 65 the last two, and by 7, all of the LED-s are turned off.
