No it doesn't matter with 2 cards. Works perfectly in Windows. Just can't OC in Linux.

A couple of options:

a) try Ubuntu 17.04LTS - it has an updated kernel that may be better with your CPU and motherboard.

b) try Nvidia' newer drivers

sudo add-apt-repository ppa:graphics-drivers/ppa
sudo apt update.

Then go to additional drivers - an every Nvidia Ubuntu driver release up to the recent 384.59 will be available for install.

Sometimes, you'll need to click open Ubuntu Software and update X Server control panel for that driver.

Remember, after switching drivers and rebooting you will need to re-enter:

sudo nvidia-xconfig -a --cool-bits=28 --allow-empty-initial-configuration

I tried but still the same problem Sad

Not a lot can be done - especially, as you won't try using Gen 2 or Gen 1!

I tried this too but didn't change anything.
I noticed that oc works on a card with monitor plugged in but this not a solution for mining.

Had chance to look into this problem and found a work-around that does not involve using dummy monitor plugs.

Firstly, log in and enable overclocking on one GPU:

sudo nvidia-xconfig -a --cool-bits=28

Log out and then log back in, then enable overclocking on all the other identical GPUs:

sudo nvidia-xconfig -a --cool-bits=28 --allow-empty-initial-configuration

Then log out and log back in and all the GPUs will have overclocking and fan control enabled.

After logging out I got suck on the login screen. Can't login again and after reboot the xorg.conf is reset to default (no oc)

Try it again, it is a workaround - sometimes it takes a couple of tries.

Tried 100x, not possible.
