Hi guys, my RX480 mining rig is having a problem here.
2 out of 6 GPUs hang after 5 mins of mining with Claymore miner, please refer to the screenshot below.
The rig is powered by 2 750w psu.

Ive tried reseating the risers and lowering the OC, but the result is the same.
Previosly the rig was running at a steady rate , after i relocated the rig, i have this problem.
Any advise is appreciated.

Two 750W power supplies should be enough to power your rig so we can, probably, rule out power problems (as a check use a power monitor on each supply - just to be sure).

A couple of things you could try.
Run the rig with only each of the 'faulty' cards individually to check if there is a problem with the cards - disconect every thing but the card under test.
Strip the rig down completely (leave CPU place) and re-build it, it's the hardware equivalent of "Have you tried switching it of and on again?", you never know what may have been knocked out of place during the move.

Thanks brother.
Ive temporarily remove the 2 faulty cards for now and will try your method in awhile. Will give an update soon.

2 possibilities:
- @ new place 2 cards are overheating
- connection is now worse for those 2 cards/risers/slots

Yes, overheating was one of the things I thought of, but screenshot looks good. The screenshot shows the rig running for only 2 minutes with temps looking OK. Would be a good idea for OP to check temp.

2 minutes means nothing. Rig was working before. Need 2 days to properly test temps, and even that is not enough as outer temp may vary much.
I just place some temp-sensitive rigs @ colder/better vented places in order to provide them to work long and even that is not enough if outer temperature rise ... Some cards just cut when over 65 celsius. Some work days @ 80s. Some mobos can't stand heat. Some PSUs too. Just 2 degrees is a BIG difference.
