I found something else, a review of a mini pc called the Voyo V3 which also uses the same atom chip.http://www.anandtech.com/show/10100/voyo-v3-review-a-fanless-intel-atom-x7z8700-cherry-trail-minipc
In the BIOS section they mention this:
"This brings us to the second issue we had with the unit - In the default configuration, the DTS feature for thermal protection is disabled. This is most likely to be the reason for crashes encountered by other reviewers when benchmarking the Voyo V3. In any case, the default option was altered, as we didn't want to take the risk with DTS being disabled - particularly since we have thermal stress testing as part of our evaluation."
They link to another review which mentions they crashed trying to do benchmarks, same issue as us. Someone in the comments elaborates.
"Ref. the driver crashes ? I think Voyo is still pretty new to the PC space ? I actually looked at the BIOS configuration, and the default settings that they have might not be good ? for example, they have disabled the DTS ? so no throttling at all when it reaches unsafe temperatures. Also, the BIOS for the x7 unit has a lot of options (mainly targeting tablet / 2-in-1 use-cases), and there is a possibility that a few of them might not have been set properly for usage in a mini-PC."
Does the WIN have a DTS setting in the BIOS @Phawx
? I'm going to take a look and see if I can find one either way.
Others might want to try and find this setting too.
So I took a look in my BIOS and found the DTS setting, enabled it.
Going to run the benchmarks again and report back if I get any crashes.
I also tweaked thermal settings (some were set to critical 95c by default!) and set them to the same as @Phawx
