Cannot get a 1070 rig to stop freezing

[Arthus110031]

First I will just start off with what I have
Asus z270 prime motherboard
Hyperx 4gb ddr4
1000w gold EVGA power supply
120gb SSD
Intel 3900 2.8ghz
2 EVGA 1070 super clocked black edition
2 Asus 1070 super clocked

I can get 3 running but when I try to do 4 it just freezes. I have updated the BIOS I have changed 4g to enabled, the DIM To first get and the other one as well ( I can't remember the one below it) graphics cards are updated. Yet every time I use nice hash it freezes. I have 4 other cards waiting to be thrown in this rig but I just cannot get it to work. I was wondering if anyone could help? Thank you for your time

Seems that fourth one is faulty. Is it brand new? Have you tried that one alone?

I also recall nicehash recommend to increase virtual memory when using multiple cards. Have you tried that?

One of the cards might be faulty or your mobo won't support it

Thanks for the reply guys. I am the one with the rig; Arthus posted on my behalf. I have proven that none of the 4 cards are faulty along with none of the risers. I have had all cards running in sets of 2 for a few days with no freeze. As soon as I put 3 or 4 cards in it will freeze when using nicehash. I followed a video on youtube and set the bios to mimic what he had working with 8 cards. The only difference is that he had 8 AMD gpus, not 8 1070s. But.... nicehash used this board to make a rig of 8 1060s. That is why I bought is.

That is strange, maybe too littlepower to those 3 or 4 cards ? Did you checked PSU ?

1070's don't use that much power so I guess EVGA 1000W should be enough.

Hey everyone. Sorry this topic was dropped, but in a effort to help anyone else who comes across this thread, I figured out the problem. Turns out that the power cable for the risers was a type 4 sata cable from the PSU. Once I changed it to a standard sata power supply cable everything worked fine for 8 cards.

good to know that your problems has been solved
usually all problems comes from this risers, cause they have sooooo loosey connections insede mainboard and so on
it is nice your rig is set to full power!
do you have problem with M2 risers?

Please do not use sata anything with your riser cards.
That crap cable that comes with the risers is an accident waiting to happen.
