Maybe I missed something, but are you sure you have degradation. There's not much difference between getting an hour vs 30min. Maybe the ambient is a little higher this time. I can run Orthos for an hour at 4.3G at 1.35v vcore, but if I have the heater running in the room, it fails after 30min. Turn off the heater and let the room cool down and its back to an hour.

On load it was running at 72-77 degrees when it failed. When it passed It was around the same thing. But a post by unclewebb say that temperature's are least of the worries. Also isn't 1 hour of OCCT more stress than Prime or Orthos at 1 hour? I've read a couple of posts saying that. One even in this thread saying that 1 hour of OCCT can find errors better than running orthos for 6+ hours.

I guess what I meant was you are still in VID range of cpu vcore, but 25% above suggested VTT FSB. And ? if high VTT FSB is just as bad as high vcore, and ? of stress testing with high VTT FSB is especially bad.

Could you raise vcore a little, and drop VTT FSB to 1.25 or 1.2 and get stable. And then see if you get any further degradation.

Anyways I increased the NB voltage to 1.450 and its 1 hour OCCT stable now. Before it was...
1.425 NB Voltage

Now to try increasing vCore and lowering VTT FSB voltage.

EDIT: Failed orthos in less than 5 minutes when increasing the vCore from 1.35-1.4 with VTT FSB of 1.225
