Hey, so I've encountered this problem today. Had a gaming PC with 980 Ti, started mining zcash and wanted to make a mining rig out of it, so I bought some GPUs. So first rx 470 came in today, I've flashed it and all works fine, mines Ethereum while its in a molex riser alright. Problem arised when I took 980 Ti out of motherboard slot into a SATA riser (connected it on the same cable with rx 470, and into same PCIe lane it was before). When I run zcash miner the card mentioned doesnt reach the volts it reached before and uses most of the time only 160W in hwinfo instead of 215W, but sometimes it reaches that for a sec, and in 30 seconds reaches 90*C with fans on 100% and shuts down or throttles in time at 85*C. Sol/s reduced. 470 doing its thing not minding. Switched riser - nothing, switched cables - nothing, switched back to motherboard slot - 980 Ti back to normal. Any clues? Couldnt find any info on this matter. Not using those included SATA to Molex cables, only PSU cable.
PSU: Bequiet Power Zone 1000W Motherboard: Gigabyte Z68AP-D3 rest irrelevant I think
