I just replaced my 4 16x to 1x riser cables with USB 3.0 molex powered cables.
Before i was hashing around 105Mh average per 24h.
Now i only get 80Mh per 24h average.
Is anyone familiar with this issue? All my other miners have the same hashrate using the USB cables, only Ethminer seems to have such a loss.
In need of your help!
4x Sapphire R9 290 Trixx, running Ethminer (latest), Win10 on H81 BTC Mobo
