My guess you use the GPU 2 with a monitor connected that is why the hashing rate is drop.
I experience this issue before in GTX 1070 and I notice that one of my GPU is connected with 1 screen then the hashing rate drops by half instead of hashing is 450sol/s it's hashing around 200sol/s to 250 sol/s.
I tried to run the GTX 1070 for almost 1 hour with the monitor off then check after 1 hour and I see the differences.
So, I suggest that you try to run your miner with a monitor off or turn off your monitor after you set up and run your miner.
Check it after few hours and look for logs if the hashing is different or not.

Try GPU 2 in a different slot and see if it changes for the better. If you are using risers I would try a different one of those two.
My 1080Ti test rig consists an watercooled Gigabyte Auros (GPU 1), a MSI Gaming X (GPU 2), and an EVGA SC2 Gaming (GPU 3).
As of this afternoon, I just noticed GPU 2 only hashing ZEC at 381 sol/s while GPU 1 is 710 and GPU 3 is 670. I haven't changed any drivers, it doesn't matter if I turn off MSI AB, reboot the computer, or the miner. This can't be good me thinks.
Things I noticed: Temp is OK at 63C, board is clean, Afterburner is showing erratic (when compared to the other 3) frame buffer, bus usage, and voltage limit spikes. Power usage is very erratic.
Do I have a bad Gaming X board? Thoughts?
