I am in process of upgrading. Started with MOBO from ASROCK, the x570 Extreme. Now a new Strix 570-E Gaming mobo from ASUS, 32 GB RAM, AMD Ryzen 7 3700x. The RAM and CPU are on QVL list. My video card is a reference Sapphire AMD Radeon 480. Over the last 2 months, I have returned 4 of the ASROCKs, and 2 of the ASUS because of posting failure. One of each actually did post, was able to do partial setup, but then failed reboot. Each time I troubleshot, updated bios to newest, 1 stick RAM, etc.. Before returning this last one, I felt I had to check with the ASUS site to see if they could tell me if I were missing something. After a short discussion, he says my video card is "not compatible" with the mobo. NOT COMPATIBLE? It isn't that old, actually worked for a bit on both brands of mobo, what happened to standards? If it fits the PCIE slot, why can't it at least post bare bones VGA? So long story short, there may be an issue with newer (or maybe just 570x) mobos not being able to use older cards. Reviewers wouldn't catch it, they always use newer cards! What is the real story here, and should poor upgraders be warned?
