Hi guys,

last days I had upgrade my computer.

Till now it was e8400/4gb ram and 2 GFX 1070 cards, both from ASUS - one STRIX and one STRIX OC revision.

I get about 450-480 sols/s each card. OC was about 20sols faster.

It had 2 old style hdd.

It was powered by old psu - bequiet 450watts.

Now I have corsair CS 750M PSU

I bought next GFX 1070 Strix OC

and finally I get SSD drive - Samsung evo 850.

Just after setting up the pc the general sols/s jumped 50% which is what I expected. The third card gave me what old cards.

After test I put the pc to the wardrobe where it was before.

And I see something really confisuing me.

The newest card give me only 50% what old cards.

what could be the reason?

afterburner shows same settings for all cards

Any hints how to diagnose this issue?

after few minutes I have something like that:

so the same level for 3 cards. Any ideas? Any hints?
