I just got a 9950X3D the other day (And a Strix X870E-E) and I am seemingly able to run a really low curve optimizer on it? If I set either 3 lower (-40 and -36) it will crash on Aida but with this config it is able to run seemingly ok. I ran OCCT and Ycruncher VT3 + FFTv4 and no errors or crashes and light work has also shown no signs of instability. Did I get lucky or am I just yet to experience idle instability?
Not posting to potentially brag, genuinely curious in case I'm missing some testing here. I did not touch PBO either.
