@Thireus You know something really weird happened. I moved to Ubuntu and it's been running well. Just today Ubuntu 18.04 popped up on my radar, so I thought I will upgrade to it from the current 16.04. Interestingly, when I boot from the Ubuntu USB, it freezes the exact same way as it does in MacOS! The weird thing is the system runs rock stably under Ubuntu 16, and Windows 10 (yuck!). I am not sure if it is a hardware issue, but it seems both Ubuntu 18 and MacOS don't like my machine- Prime95 is not enough because it will not reach all your CPU functionalities and will not randomly mess with them. I'd strongly encourage you to conduct further testing with Cinebench 20-50x in a row (keep hitting that Run button) on both Windows and MacOS. It happened on many occasions to me that my OC was rock stable with Prime95 running for hours, but would immediately crash after 5-6 runs in a row of Cinebench.
- Regarding the RAM I can't really tell honestly. I've never had bad memory sticks, but I've conducted several memtests both in Windows with a memtest app and also by booting on a memtest ISO, always passed.
- Make sure to uninstall Nvidia too, even if that means having a non-functional GUI with lags for a few days. The idea is to have your system up and running with the minimal third party stuff. That's the only way you'll be able to find where the issue is coming from.
- For GPU testing, Heaven and Valley are really not enough. I couldn't get my system to freeze with them, even after running them for 24h... The only app that I found could trigger my system freezes almost instantly is a free game called Fortnite, because this game uses the latest GPU-related instructions and functionalities that were barely supported by Nvidia drivers (and effectively they were indeed buggy).
- Honestly I highly doubt my EFI has hidden magic. Like I said, things should be pretty straightforward now with the latest Nvidia drivers (now that they are finally working properly).
EDIT: ok I downgraded to BIOS 1102 and things are back to normal - windows and ubuntu are solid. MacOS seems to be running fine too (but I suspect it will crash/hang soon). So it seems my problem was a buggy patched BIOS.
