After systematically replacing every component in my computer—including the 9800x3d processor, B650e motherboard, 32GB DDR5 memory, and 1000W power supply—I’ve concluded that my Red Devil 6900xt Ultimate graphics card is the source of persistent green and black screen crashes. The only way to maintain stability is to significantly reduce performance by limiting the core clock to 2000MHz and implementing a -10% power limit.
Initially, I suspected thermal issues due to high core temperatures and reapplied thermal paste, which successfully lowered temperatures but didn’t resolve the crashes under load. My research revealed that approximately 80% of similar cases involved other Red Devil owners, with most ultimately requiring card replacement to fix the problem. If anyone has encountered this specific issue and found an alternative solution, I would appreciate any insights.
