Crashing rig while mining ETH

[ljbawss]

Hi,

I´ve been mining ZEC and ZCL successfully for some weeks now with my 6 RX580 rig but it keeps crashing immediately when I open Claymore Dual software for mining ETH. The entire rig shuts off and restarts within a minute. I flashed the cards with original bios but it didn´t help. Also tried different drivers, Blockchain drivers and newest drivers but none change anything. If I unplug one random card it does mine ETH stable on 5 cards. My PSU is a new Corsair 1200W so I think it's powerful enough..

Anyone who has an idea what´s wrong or know some steps I can take now?

UPDATE

So I tried playing with the following commands:

-ethi
-eres
-gser
-dcri
-lidag

But with 6 cards the rig always crashes within 10 minutes.
The only thing that works is the command -di to disable 1 GPU. Rig is running very stable for days with 30MH/s each with 5 cards enabled.

Anyone with an answer?

have you already increased your virtual mem to at least 16GB or more?

For multi-GPU systems, set Virtual Memory size in Windows at least 16 GB:
"Computer Properties / Advanced System Settings / Performance / Advanced / Virtual Memory".

To be honest, to me it still sounds like a PSU issue. Your PSU might not be powerful enough or maybe something is wrong with it.

Yes I did. Also tried 48GB because I read somewhere you should take the same number as all your GPU ram's together (6 x 8GB).

Okay thanks, guess I'll try to power one GPU with the PSU from my normal PC.

Totally agree with you it smells like not enough power for 6 gpus.
