That's AMD's graphics driver. The patch isn't for fixing errors. It's to get around certain driver limitations. Frequent driver crashes usually indicate a hardware problem.

It's only happening when I OC the dedicated GPU (unnoficial way, extend official overclock limit from MSI afterburner enable wattman for overclock)

Then don't overclock the GPU. Clearly the GPU can't handle it.
Can you think of a reason why an nvidia card can drive my LCD panel to 120Hz 1080p and still have integrated panel sound speakers work on both HDMI and displayport, but AMD cards can only do at most 95hz with sound, or 100hz without sound (CVT reduced blanking) on both HDMI and displayport? Is this an issue with driver limitation or some other issue? The issue seems consistent between many makes of AMD cards (280X, 380X, RX480)

This is given identical hardware (PC, monitor, cables, OS, software, etc). Only difference is the video card and associated driver.

HDMI transmits audio during the blanking periods, so use "LCD native" timing, or add 1920x1080 @ 100/120 Hz in a TV resolutions data block in the extension block to make sure it has enough blanking for the audio. DisplayPort audio is transmitted separately, so the resolution shouldn't matter as long as there is enough bandwidth remaining.
"Getting started:
Run atikmdag-patcher.exe. (If you only need the BIOS signature patch, rename it to atikmdag-patcher-bios.exe first.)"

Hi, so I' not sure how I should be using this tool for my card. I bought a 2nd hand mining rx 570(like one of those legit made for mining 570s that only had the dvi output even. looks cool tbh) for a backup computer, and it has a modded bios that works fine in linux but when I try to use windows it well doesnt work with the drivers installed. I've been told I need to use the pixel clock patcher to get it to work. But I dont know if I need everything or just the bios signature patch. Like described in the part 1 of getting started.

that one thats the one I bought second hand. never used though still in its packaging when i got it. Just dunno what i should be doing to mess around with it in windows. Im guessing there is no gaming bios for it but meh if I can get it running with the latest driver (maybe overclock it some but i doubt that) it'll be a good backup rig. being a bit better than the 390 that died and its replacing.

You just need the BIOS signature patch.
Thanks, ToastyX! Hopefully work isnt crazy so I can try it this week but eh if I gotta wait until friday I can/will. but still thanks
Will i need to run this each time I update drivers or just the once?
