I need to correct you on something here Johan... You said "since the launch of the 5000 series yet nothing has been done to fix it."...... That's not true at all......... This exact same issue plagues AMD GPUs going all the way back to the introduction of Radeon, and nothing has been done to fix it!!!! I built my new system last May, and I've had several issues with nothing but my Radeon RX 570 ever since. I have lost literally months of work time (video and audio production) trying to resolve all the problems I have with this GPU.
I had a specific budget when I built this system, and chose, what I thought based on tons of research, the best components for the purpose of the system I could get based on that budget. I've been building systems since I retired my Commodore 64 (yes... I'm a dinosaur LOL) and I have NEVER had so many issues as I have with this one frikin GPU!!!!! I've been resisting RMA because to do that I will be without a GPU, therefore a system for work, for who knows how long until they refund my money so I can get an actual working GPU......
I've already lost months of work due to this, and had turn down lucrative contracts as well, because I KNOW I wouldn't be able to meet the deadlines of the projects because of the time I would be down due to this GPU. I have spent months trying all the tests and troubleshooting advice I have found here, on reddits, on other sites, and even with the help of friends who are actual PC and software engineers and still I am faced with near immediate black screen after starting the system. That's it.... Just turning the damn system on!!!! It starts to flicker for a bit and then BAM black screen, it's now changed to green screen with the 19.12.2 and 19.12.3 releases..... Not sure if the green screen is an improvement over the black screen or not.... Hmmmmm, maybe AMD is mocking now.... Reminding me of the the green I'm losing using their product.....
I have used all the top end debugging and trouble shooting tools there are in trying to resolve the issues I've had with this GPU... I have submitted all the debugging reports to AMD support, only to receive the usual canned cookie cutter responses that everyone receives regarding test your memory, run scandsk, check your PSU, Use DDU to uninstall your drivers and reinstall the new drivers, yadda yadda yadda, yackity schmackity, blah blah blah...... Hell... I even resorted to asking Bill Gates and Steve Jobs (via seance) for help.... Bill ended up with a brain melting migraine, and Steve crawled out of his grave and slapped me, and called me a beeotch for enduring the torture this long.....
I'm done!!!! I am submitting a request for RMA effective immediately... I can't keep doing this crap, especially since AMD has been 100% fully aware of this issue on MANY of their GPUs for YEARS, yet has done little to nothing to resolve it. I apologize for the lengthy rant.... I needed to vent..... But I hope this answers your question about whether or not to RMA your GPU, Johan.....
