    Posted: 19 Jun 2020 at 6:35pm
I just upgraded to this new GPU from an Nvidia GTX 1060. I plugged it into my MSI Z370 GAMING PLUS motherboard, and installed the drivers and software I needed. Initially, the RGB lights were on and working. I downloaded Polychrome Sync so I could change the colors, but nothing I did in the program would actually change anything.

After a reboot of my computer, the program doesn't work at all. It keeps giving me an error saying "There is no Asr graphics card and Asr USB LED header!" At some point while trying to fix the problem, the LED lights just stopped turning on at all, so now it doesn't show any light.

I've run DDU to ensure any remnants of my old GPU was gone, I've updated the vBIOS for this GPU, I've uninstalled and reinstalled the drivers and the Polychrome Sync software numerous times, and I'm at my wit's end with no idea of what to do next. At this point, I'll accept just getting the lights back on. Any help would be greatly appreciated!

I do have the same issue, so any answer from AsRock would be great (besides send it back to seller for warranty). I saw there was a Led Firmware, but the link seems to be broken.

Thank you very much. Everything went OK and now there are no such problems with RGB synchronization. Now, however, there is another major problem after the update. When the card is on the OC BIOS does not load. When you move to Silent bios everything is correct. Can you give me some advice or resolved. Thanks.

Dear Logmax,

Thank you for your reply.

Regarding your case, you can try to boot up the system with OC BIOS and use onboard graphics to re-flash the vBIOS.
Download link:

Thank you!
