I bought 2 nvidia cards, 1050ti and 1070. I have tested both separately in my i7 7700 @ 3.60GHz, with good estimated PPD: 1050ti = 150k, 1070 = 600k without any OC yet, both cards > 95% core load.
Then I manage to put both cards into my mining rig (old computer: gigabyte EP43-UD3L with Core2Quad Q9550 @ 2.83GHz) with PCIe riser. Running Windows 10 as well, 1050ti = 120k (slightly lower but still acceptable) at > 95% core load, but the problem is 1070 = 400k with only ~78% core load. But the weird issue is I have full 100% core load for both cards by using ccminer or other miners.
I have tried some of the suggested solutions such as swapping PCIe slot position, power option to High Performance, but still no improvement
