(In reply to Chris Waters from comment #127) > Second question, is there any way to just force the memory clock to stay at > 1500MHz? If the bug is caused by memory switching (and not the memory being > clocked way too high), then forcing the memory to stay at the max standard > clock should give us the stability of 150MHz. Some months ago, I thought it was just mclk switching. But today I am not so sure about it. Executing the following steps on my machine with an R9 390: - lock mclk to 1500MHz - start playing Mad Max via Steam - switch to the game map via gamepad or keyboard (https://www.google.sk/search?q=mad+max+game+map&tbm=isch) results in noticeable screen image flickering. If I disable the lowest 300 MHz shader clock, so that the minimum shader clock is 500 MHz and maximum is 1000 MHz, the flickering disappears.
