1. Disable SIP (csrutil disable from Recovery)

2. Move AppleThunderboltNHI.kext

   sudo mv /System/Library/Extensions/AppleThunderboltNHI.kext \
   /System/Library/Extensions/AppleThunderboltNHI.kext.BAK
   

3. Reenable SIP (csrutil enable from Recovery)

Ok. Finally. I found somewhat like working solution.

RealMacMods NoCrashMBP It looks like a scam. Truly is. It is website with no links to, no citing in google. It is really looks like they want my 2.5$ and that's all. I decided to take that risk ($2.5 lol) Because only good solution I saw was to replace logic board, as many solutions in internet say. It is 500$. It worked. I have to say it to everybody with the same problem. Authors explanation is:

Anyway, this issue is triggered when the CPU goes into an extremely low frequency/clock rate on one of the cores(that just can't handle it), when this happens the system somewhat silently crashes(that is to say, it writes no logs of the event, and no kernel panic takes place). This app/utility keeps it from ever going into that stupidly low frequency. This actually happens natively on Linux and Boot Camp installations, but for some reason OS X tries to drop into that frequency every so often and the system is not at all stable there. Absolutely no chance of damage, worst case you may see like 1% worse battery life, as i believe OS X is using that low frequency to squeeze a little extra battery life out of the older MacBooks.
