6x 1070ti simplemining OS issues, maybe power?

[msj219]

After enough bashing my head against the wall I've come here in hopes of getting some answers from more experienced miners.

Here's my setup that I'm having issues with

- 6x EVGA GeForce GTX 1070 Ti SC GAMING
- MSI z270-a pro mb
- EVGA 1200w P2 PSU
- 8gb RAM

I'm using SimpleMining OS

I can't seem to get this setup to run, seems to be some sort of power issue which I don't understand why I'm having as people are reporting online that they are running similar setups fine even on a 1000w PSU.

Undervoltted everywhere from 100-170w on the simplemining OC menu and no luck, a lot of the times I get some kind of cpu error on one of the gpus and it never even gets to simplemining OS.

Separated the cards into 3x 1070ti per 1200w P2 PSU on two separate rig setups and they ran just fine dual mining at 170w.

I've gotten 4x to run as well no issues.

Currently I'm experimenting trying to get 3x 1070ti and 3x 1070 to run on a 1200w but having issues with that as well.

I'm guessing there's something really simple I'm missing here or is it simply that I don't have enough power from the PSU somehow?

Nvidia specs say that each card requires 180W power, so for your setup its 180x6 = 1080 W, adding CPU+motherboard and all other accessories along with it , I guess it must be that there isn't enough power for all cards to run in the same rig (since you have mentioned successfully running the same card x 4 in the same rig). Try with another PSU if you have access to them, like 1300W or higher. It is always better to leave a little room and not saving too much on the PSUs since it is a very critical component (have seen many people suggesting this here and also on ethereum forums)

Ive got a Ryzen 1700x, Msi Aero 1050ti (mining and for video output) and 6x EVGA 1070ti set to 70% power limit and it pulls 1000w from the wall. The 6x1070ti on the previous set up were still pulling 850-875w frok the wall so i would say your psu isnt enough.

Be more specific please if you need help. Saying "some king of error" begs for "some kind of rig rearrangement" type of answer.
