This is a question that have been asked in our Mining group on Facebook.

Can anyone help?
when I plug in second gpu my Mh/s dropped from 30 to 25 for each card.
How can I fix this

E: How are you connecting the gpu? Riser or straight on the motherboard? What size psu do yiu have? What cards are you using?

Q: Straight on board. 1000w evga g3, sapphjre nitro+ 8gb special

E: Do you use msi afterburner?

Q: Yes msi afterburner

E: All clock and memory speeds set to the same? I ran into an issue where mine changed to default when I added a 3rd card to my Setup

Q: Yes. It sync across all gpu, maybe my driver isnt good. Do you have link to which driver you using?

E: I actually had just recently swapped to Nvidia cards. I used just the drivers from amd. The Crimson drivers worked well. I think I had used the older ones from 2016. I later got into flashing bios and such which has its own risk but it paid off. I later sold the cards for what I paid for them, even after the abuse they went through.

Q: Nvidia better? 1070 ti?

E: I have two 1070s and two 1070ti cards

Q: Very nice, Eric

Q: Fixed. it was the driver. thanks guys
