Haggyy,

I have the *EXACT* same problem as you.  I've spent the last 12+ hours debugging to no avail.  I've read every post online umpteen times before I saw your post and realized it was recent.  I see the same blasted Code 12 "not enough free resources" error on my cards.

I'm uisng 6x GTX 1070 cards and 6 powered risers on the AsRock H81 Pro BTC R2.0 motherboard.  I have 8GB RAM in my rig and I can tell you the amount of RAM doesn't matter for this issue, probably not worth you upgrading.  My PSU is a Corsair 1200W platinum, not that it matters.
Even though I'm using 6 cards, I had the same problem with fewer cards.  My first 2 cards worked fine so I ordered more.  After I added 2 more cards (total of 4), I could only get some of them working.  When my last 2 cards arrived (total of 6), 4 out of 6 are working.

4 of my cards work great and I can mine on them no problem.  2 of the cards have the yellow bang in Device Manager.  

I also disabled non-essentials in BIOS, changed out risers with working video cards, reloaded Win10 from scratch, checked and re-checked all connections, set virtual memory to 16,384 Mb, set Bios to gen1, NONE of it works.

Both molex plugs are in the mobo.  I also contacted AsRock, they sent me the 1.30 beta Bios and said turn on the "4G Decoding" setting but it didn't work.

This is my first time building a rig and it's working, but at two-thirds hash rate...

I've re-ordered risers to change them out to see if that's the issue since I see some forum users reporting bad risers causing this.  After trying that, I'm going to return the mobo and get a replacement.

Have you made any progress?
We may need to start a therapy support group for the pain and suffering caused...
