Hello guys,
I have problem with my rig. Several days ago Claymore zcash miner began crashing. I get message: GPU 1 hangs in OpenCl call,exit. And after that miner freezes. What can I do to solve this problem?
I had once with my 4rd gpu which is a r9 270. the other 3 gpus are r9280x with no issues.
When I inspect the rig carefully, I saw that the power cable to te r9 270gpu (a single 6pin socket with converter from molex power socket) is changed color and when I pull it out, one of the pins was burnt. and the molex power cable from the psu had burns too. I changed the cable from the psu, thanks to the modular psu cabling. Bought another converter from molex to 6pin pci-e power and reconnect everything. it's working without issues now.
Check the power cables and power.
