Hello,
I have problem.
Who can help me?
I have mining rig hardware:
Software:
My cgminer.conf
With this configuration 3x GPU cards running stable. But when I connect 4 card and run cgminer works very bad and turnoff motherboard. But PSU still running.
Who can help me with this problem? Maybe not impossible run rig with 4x GPU's? Maybe my configuration is wrong? Or I forget something to install?
Than you in advance,
TDS

With this config you should be able to run those cards, but the problem could be either something with Windows when connecting the 4th card. I believe I have seen posts on this.
But, it also could be a heat issue.If the cards are not breathing properly, then they are overheating, and your mining is getting shut down.
