Hi. I was doing some tests a few days ago using two nvidia GPUs, one 1050Ti/4Gb and one 1060/3Gb. The motherboard on which I was running the test has one PCIe x16 slot and one PCIe x1 slot. So for the PCIe x1 slot I had a typical powered raiser/adapter. I tried ETH and XMR mining and got the following results: 1060 3Gb x16 slot ETH: 20.3 MH/s (ethminer) 1060 3Gb x16 slot XMR: 290 H/s (xmrMiner) 1060 3Gb x1 slot ETH: 21 MH/s (ethminer) 1060 3Gb x1 slot XMR: 100 H/s (xmrMiner) 1050 4Gb x16 slot ETH: 12.5 MH/s (ethminer) 1050 4Gb x16 slot XMR: 190 H/s (xmrMiner) 1050 4Gb x1 slot ETH: 12.5 MH/s (ethminer) 1050 4Gb x1 slot XMR: 70 H/s (xmrMiner) So it looks like on XMR mining the card that is connected to the PCIe x1 slot had a performance penalty. While on ETH mining the performance didn't show any difference. Does anyone know why? Is the xmrMiner using the system's memory and requires more bandwidth to the memory bus or something?
