What I tried:
- all on default optimized = stable for >8 hours
- used 6 working OC profils from here and the net with same CPU and board including Pstate ones = crashes/freezes
- all Auto - 39x Multi = stable but 88° after hours
- Vcore offset +0.025/LL3/DRAM 1.35/SOC auto = shuts off above 90° after hours
- GSAP and Memtest passed days memory testing
- replaced the cooling paste - helped some degree
- last setting x39/VCore 1.4/LL1/rest voltage auto/DOCC profile
Not even close, I got the worst 1700x chip on the planet, for 2 years I run it at 3.9Ghz at 1.4375 LLC3 (1.406-1.412v on load). Now I run it at 1.4v LLC3 at 3.85Ghz, summer is coming and 1.4375 is too much. For cooling I don't have nothing fancy, a thermalright true spirit 140 power with a ty-143 fan and the ramp up noise is annoying.
Asus C6H Bios 6401, 1700x at 3.9 all cores.

Most instability comes from DRAM, you need to tweak ALOT, don't use XMP settings even if they are "Ryzen compatible", not even AMD knows what settings are right for a specific chip or sillicon.
Also instability is caused by temperature, Zen doesn't work the same at 65C and at 75C. Even if you are stable at 75C benching, maybe it will crash at 65C when doing nothing.
