Premiere Pro has the ability to hit your whole PC hard during renders. And, if you have any weak link in your system, it can lead to problems that may not be evident when doing memory, cpu, and gpu benchmarks and burn-in applications by themselves.
Do you have all of the latest and greatest drivers for EVERYTHING on your motherboard?
What is your power supply?
What is your motherboard?
Have you monitored cpu / gpu temperatures during the rendering process? If so, what are the peaks?
Suggestions to try to gain stability that can lead to an understanding of what is getting pushed too hare:
- Slow down you cpu clock to 4.0
- underclock your gpu slightly
If you can do some change that gives you stabiltiy, then you can tweak from there to gain the best performance and with complete stability.
