I am about to lose my mind and would appreciate any help regarding the below problem Huh

3 rigs, all same, G4400, Crucial 4GB, Asus Prime Z270-A mobo, 120gb SSD, 6 x MSI GTX1060 6GB OCV1, CM 1000w PSU - working for days (+125 core, +1700 mem, 90w)
3 rigs, all same, G4400, Crucial 4GB, MSI Z270 SLI Plus mobo, 16gb flashdisk, 6 x MSI GTX1060 Armor 6GB OCV1, CM 1000w PSU - 1 for working for days (+125 core, +1850 mem, 90w), other two is giving me headaches!

I built the systems on my own, I did the BIOS settings and checked 100+ times that they are the same, using the latest available bios, changed risers, slots, power cables etc.. 100+ times. Whatever I do, one rig continues to work flawlessly, without any restarts for days, but the other two (which are exaclty the same with the first one - even the screws) are restarting, losing GPUs (showing 4-5 instead of 6), showing irrelevant core/mem values, not applying OC etc...

I tried without OC, new USB, new risers, new everything, setting up from the beginning, flashing new os, nothing worked so far.

Whan can cause this? Everything is same to the bit for 3 rigs, they are in the same room, 1 is working, 2 is not. Appreciate any input, it has been 10 days and I need to start stable mining ASAP.

Just an idea, but be mindful of your power situation. I have 4 D3's and they will throw errors if I run too many in the same room because the house wiring is weak, there's not enough power for all of them. If it doesn't trip the breakers, they will throw the errors. Another issue could be your power cables. You want a 14 gauge I believe? And you want them short, longer cables lose efficiency per foot.

The fact that 1000 watts powers one rig fine but fails to do so for the others indicates a power sourcing or delivery issue to me. Potential fire hazard. Take care with your other PSU cables as well, I've read they can catch fire sometimes if overloaded. Better safe than sorry.

Another idea could be poor internet connection that causes errors while updating, ip conflicts or data dropping, but that's unlikely.

Lastly, it could be a problem with the OS itself, which also seems unlikely.
