What Xaltar said is 100% true - gains from 3.8-4.0GHz are marginal except for a few benchmarks. If your intention was to render or crunch 24/7 under extreme speeds, then I'm afraid you choose the wrong platform for this. Invest more time in faster RAM, it works wonders for Ryzens.

I am going to call bull$hit on this, dust within a few months my a$$.  I have been running 1.45 v-core on my R7 1700 for months (since May 2017) at 3.95 to 4.0 GHz (although the highest "stable" clock is 3.975, took me months to be able to get it to run benchmarks at 4.0 GHz).   It will run all day at 3.975 GHz (depending on the BIOS version - the latest BIOS made me drop to 3.95 GHz to have the reliability I wanted).

That said, my rig is water-cooled, which I am sure helps.  I also have a separate fan blowing directly over the VRM to ensure that the temps remain well below the rated capacities.  Getting past 4.0 GHz, my unlucky R7 1700 CPU will balk nearly every time (where my "good" R5 1400 will run 4.1 GHz on air cooling!).  I might add that none of my Ryzen's which are ALL clocked at or above 1.40 v-core have been rock solid 24/7 (2 air-cooled 1400's 3.85 GHz and 4.05 GHz and 1 water-cooled R7 1700 at 3.95 GHz).

Does it place these CPU's at risk of early failure, sure, no doubt it does.  Is it a matter of turning them into dust "in a few months"?  Not even close.  Control the temps and the hardware will certainly last longer (and perhaps with much less risk than commonly thought).

Is my data anecdotal and an insufficient sample size, yes, but it is data which suggests that Ryzen might tolerate more voltage over time than some might believe.  FWIW, I might be bottlenecking my GPU's but that's two 1080ti's in SLI - at which point, who cares.  One last note, I maxed out the ram at 3333, but the timings were really loose.  Performance was much better on the Samsung B-Die running 13-14-14-14-28-40-1 timings at 3200 MT/s  (260-192-118 tRFC)

Water cooling does help with temps. ie: voltage related excessive temps

But otherwise, I'm going with you stating anecdotal. It is still somewhat early to definitively state such as anything but as personal experiences yet.
