5900X (PBO +200mhz) + Aorus Ultra x570 (rev 1.2) + Radeon 6900X (AMD edition) + 32 GB CL14.
Upgraded my 5 years old system without reinstalling windows! Finished today.
Except few crashes no problems for me. Everything is running default. Temps are generally between 50-60 degrees Celsius. All settings ultra (also 8x8 and 2048 terrain Shadows for testing).
Flight Simulator cannot utilize hardware yet, waiting for july 27 update. Neither GPU or CPU goes over high % usage for long. (Resolution 2k).
My honest opinion this is so stupid. My previous setup was 6700k with 1080. I have been playing since Tech Alpha and has less than 5 crashes so far. With this upgraded system 3 crashes so far. I hope DX12 and engine rewrite solves this weird problems.
EDIT: Forgot to mention, i defined custom fan curve because with default one it was around 75-80 degrees even tho i have perfect case airflow. Now with custom curve, never see 70 degrees and limited fps, disabled all enhancements from Radeon UI, looks like stable so far.
