Hello,
I have been having this problem for quite a while. I tried every possible solution I can think of to no avail.
I am hoping someone here can help me solve this problem.
I have a mining rig with 6 RX480 graphic cards.
Last June, the machine started to restart as soon as it starts mining. No log or anything is left (Log is empty)
I thought first that a graphic card a riser or a slot on the motherboard could be faulty.
Further investigation resulted in the following: None of the graphic cards are faulty. Tried all of them.
None of the slots are faulty.
2 of the risers were faulty. Great, easy changed those risers.
Powered up the machine, with 6 graphic cards, restart again. No log.
Powered with 5 GPUs, restart, 4 the same.
Powered with 3 GPU in single mining Ethereum .... machine is okay... kept it for a week .... no problem
Stopped the machine, added DCR Dual mode. ... machine restarted..
At some point I thought it could swap, the machine is now running on 24 GB of swap but that did not solve the problem..
I have no idea what is happening. I am thinking PSU but would like to see if anyone can suggest anything. I am running on 1200W evga supernova
I will be really thankful if anyone can give any hint.
Note: the machine has been running on 3 gpu since july with no problem and I had no time to try to figure out the problem until now.
Thanks and sorry for my long post
