Hello guys ... need some help or directions

My configuration:
Motherboard: Asus Prime H270-Plus
GPU: Asus GTX 1070 DUAL 08G x 6
PSU: Gigabyte XP1200M - 1200 w 80 plus platinum
SSD: 128 Gb ADATA
RAM: HyperX Fury 8 gb DDR4
OS: Win 10 Pro

I have installed all the latest drivers + CUDA

All cards are on power risers VER 006C

So far so good, but ... when i try to mine with EWBF or Nicehash miners it does not take too long for the rig to reboot.
I`m using MSI afterburner in order to over/downclock the cards.

I try them one by one and they work very well ... i can get 470+ sols/s per card, but when i put them all together they are starting to crash the configuration. Everything is fine with 4 cards , but when i add 1 more and the reboot repeats. First i taught that the problem is in the PSU, but i try ETH mining with huge overclock and i was near 1000 W and it was running ok. After that i underclock and start zcash mining and until it gets 800 w it is ok ... after that it starts to crash. If i underclock all the cards and set the power limit to 70% for example it works. I think it also worked for 75% of the power limit ... after that it crash. For ETH i set the power limit to 98% for all cards and still no problem.... no crash... so from here i just decide that the PSU is not the problem. Also the cards when tested one by one are not crashing. The temperature of the cards is not more then 70 C ... usually 65 C. The temp of the CPU was under 45C.

I`m really out of ideas. It will be nice if someone can help me with this. If i forgot some information pls ask

I have the same problem. But i have enough PSU and rig was working fine 1 month in a row. i have 2 PSU . 1 is 750w Corsair for motherboard and 2 gtx 1080 and second is 850watt Corsair for 3(4) gtx 1070 (i cant put the 4'th cause windows error on the boot). After i tried to put the 6th one i have this problem too. It tooks 10 minuets to freeze or restart...It was doing well before so i dont have any clue why it does so. I toggled of overclocking and updated the drivers but the problem remains... who can give any advice?
