Hello everyone Since the moment i assembled my pc 5 years ago i ran into quite a few problems with my r9 fury, insane texture streaming issues and z-buffer issues in almost every 3d environment, coupled with constant ctds and random shutdowns. solution that worked for me ( originaly ) was to use 15.7.1 catalyst drivers with a semi-deleted drivers from 17.11.2 crimson, on top of forcing every registry line with EnableUlps into 0, simultaneously launching clockblocker, and msi afterburner undervolting and underclocking only to get it work ( what was funny though, is that benchmarks ran perfectly fine and presented 0 errors ). And after roughly 3 monts of rectal intercourse with my pc i was finaly able to use adobe premiere / d3d11 games / 3d aplications without crashing to desktop for longer than 15 minutes up to 8 hours and more when needed. Though recently i had to replace my fans on the gpu. Recently i got this new issue which is basically what i had when i first assembled my pc. After a while (8 - 15 minutes) 90% of 3d aplications crash and if i check log it just says: Display driver amdkmdap stopped responding and has successfully recovered. And also a system freeze if you're unlucky ( but the sound is fine and i can hear the stuff is running or even use skype/discord, so i thought it's a driver issue ). MSI afterburner shows normal temperature never going above 83 degrees. One thing i noticed is that crashes frequently occur when gpu load has a sudden spike to 100% then back to 0% then again 100% and then display driver crashes and restarts. Voltage goes spiking down then back up too ( though it begins with spiking down for like 2.5 seconds ). It's 100% not a temperature issue cause benchmarks still do perfectly fine and besides temperature never goes above 85. Next on the line was voltage - i tried to undervolt - no result, tried to crank up voltage - no result. Reduced core clock from 1000 to 800 - no result. It looked to me like it's a ULPS issue or one of those amd power saving tricks, but i thought i disabled it in register, and clockblocker is running too which is supposed to prevent underclocking that amd loves so much ( for reasons that elude me, even though every friend i know has issues with underclocking ). After like tinkering with settings for 100 hours i get stuff to work, and i have no crashes in 3d apps untill i shutdown my pc, then it's crashtown all over again. I thought it might be my PCU, but why on earth does it work after i dance around it for 20 hours then? Thought it's faulty ram - still nothing.
