Has anybody succeeded in overclocking the memory of the second GPU in case of Crossfire Fury?
I tried eveything, disable CF, disable ULPS, which failed even after manually disable "enable ULPS" in the registery.

Yeah I had Rev 1.0 of the videocard and I could do that too when the card first came out. But after a year I took it back to warranty and got Rev 2.0 as a result. By that time Gigabyte the ***holes had already released the GHz edition of the HD7970 and decided to voltage lock the HD7970 OC Edition.
I highly doubt any of your cards are REV 2.0 or REV 2.1
Only Rev 1.0 of the card is voltage unlocked. It's not a BIOS issue, or an MSI Afterburner issue. I am pretty sure I researched this and there was a whole thread of 200+ dedicated to testing whether or not REV 2.0 and 2.1 of the card can be voltage unlocked (even those that succeeded in unlocking via BIOS mods) after testing the voltage via hardware, noticed it wasn't actually unlocked.
This is the main reason I don't touch anything from Gigabyte. They do the same with motherboards too. Rev. 1.0 is fine (so that reviewers get the good stuff), then Rev. 1.xx/2.xx is silently released with worse materials etc, at the same price range. Meanwhile you still believe you get the product that has been (honestly) reviewed as good. There was even a story in Guru3d about it. People in other websites have actually tested two random Gigabyte motherboards that they had the different revisions off, and you can see the results for yourself. It is Sapphire/ASUS/MSI for me, in that order.Kingston is doing the same with SSDs. Even Anandtech had a piece on it.

"Feature levels" line and data is in dxdiag of 8.x and 10 only? Here's my 7 SP1. Just curious why it's not shown mainly, and my previous sentence is a guess.
AFAIK, DX10 and below do not have feature levels.
only DX11+

Your 7950 doesn't support the 12.0 feature level. 11.1 only. It supports DX12 though so don't worry.
