your clocks are too high
set them at 145 for core
and at 1000 for mc
480 sols meant you stretched to the max
with 175 and 1200
once they work with
145 and 1000
bump
to 150 and 1000
you will be closer to 450 sols but it won't crash
Thanks for the input, yesterday i managed to put the rig back and running (i belive the problem is the USB drive since it now has happen again and the rig was back and running after formatting it).
I went down in MC to 600 and CC to 150 as soon as i managed to boot the system and was getting around 460sol per card.
Now i'm starting to think the problem is the USB driver where i have the OS. The system again was running great for about 24hrs and then stopped working and it only boots nvOC to the login screen, when i try to log in with the password it reboots. I'm now formatting the USB to intall again nvOC to make sure that the problem is there, waiting for Lexar drive at the moment, but i think i will end up going with a ssd
