TL/DR: New Ryzen System reproducibly crashes a few applications(mainly Blender, most run perfectly fine) , RAM timing issue or RMA case? Hi, for about a month I got my new Ryzen 3 (Zen 2) system. For the most part is runs buttery smooth and as expected. Specs are: Ryzen 3900x Asus x570 Strix-E Gaming, 184.108.40.206 ABBA updated G.Skill Trident Z Neo, F4-3600C16D-16GTZNC, Hynix CJR Nvidia GTX 1080 bequiet 680W PSU BIOS-settings are on default(updated to ABBA 220.127.116.11) except I activated the DOCP profile for my RAM (which is on the QVL of the MB, btw.). Chipset drivers are installed both first from AMD directly then from ASUS again, as is stated in the description of them on the ASUS page). Played some games (Mordhau, Greedfall, Battlefront 2, several others) everything works fine. Rendering with FFMPEG works fine too. So a few days ago I installed Battlefield 5 to see how it performs (hadn't played on my old rig in month) and it crashes to desktop, sometimes after a minute, sometimes after one or two matches. As this is Battlefield which has been prone for crashes like this I though lets try some more things, and a few games and tools really show similar behavior after trying quite a few from my library (for example "Exanima" starts on DOCP V1 but just freezes after a few seconds, "Between the Stars" shows a similar behavior). What really shocked me was when I installed Blender and fired it up and it just crashes after a few seconds (maybe 10-30). I began fiddling with my RAM timings, tried BF and Blender with some different settings: all on AUTO(so 2133HZ), manually set DOCP values and suggested values from Ryzen RAM Timing calculator both "Safe" and "Fast. The behavior stayed the same, some settings felt a bit more stable at first but in the end it stays the same. Note: I never had a BSOD so far, and I monitored my temperatures for processor and GPU, which are both well inside specifications, in case that helpes pinpointing. Now I am at a loss, I ran a memtest from USB stick over night with DOCP activated and this did not return any errors, I really am not sure what the culprit might be now. Does anyone maybe have a similar or even the same combination of RAM and MB and might sahre some comparison on behavior? Might it be a BIOS issue, or rather some DRAM timings? Havent really overclocked in years, so no real experience regarding this. Maybe someone here know about similar issues or got any ideas, let me know if I can supply any more information regardings this to track this down. Thanks in advance!!!
