with the new BIOS. Makes me wonder why memory timings are not that optimized, since that would be the only thing that changed
Most likely memory optimization on the 290X's was lacking due to GCN 1.1 being a brand new architecture at the time of its release; and AMD not having much time to spend strictly on "optimization" in the face of stiff competition from Nvidia. AMD needed to get the R9 290X out the door in time to draw sales away from Nvidia's 780 Ti which was set to release shortly after the 290X.
But, during the approximately ~20 months between the release of the R9 290X and the R9 390X, AMD had plenty of time to sit around and think about how to bring out the most possible performance from the 290X without changing its hardware at all. This mean't it could be rebranded into the R9 390X, but still include a visible performance increase to the end-users.
That is just my speculation though...

It's a lot of variables to go through...
It could be my ROM, I started using one of these custom ROM's somewhat early on, and I know several revisions were put out beyond what I have loaded up. Maybe the final revision (yours) work better on Win 10.
I'm sure you will be able to find a lot of feedback from people running W10 in this thread. A lot probably already exists as well if you are willing to read back in the thread a bit. But yes, upgrading the OS does change a lot of variables at once that could be causing various problems for your previous OC.
As far as your ROM goes, if you really are using one of the first revisions I released, then I would strongly recommend upgrading to one of the latest revisions, preferably ver. 1.8. The reason that these BIOS files got revised so many times was for the sake of stability. Just make sure you use GPU-Z to back up your current ROM before updating, as I don't think I have any copies of the previous revisions saved unfortunately.
Back when I was still developing these BIOS files I did not have any problems running them under Windows 10, as nothing was changed inside of the BIOS files that would affect OS compatibility. These modded BIOS files should allow the card to be used by any
OS, just like a "stock" BIOS file would. I will be curious to see what solution you come up with for this instability problem. Personally, I bet updating the ROM would do the trick, although when you update the ROM there is no guarantee that you will be able to achieve the clocks you did on the previous ROM. Although who knows, maybe you could push it even farther with the new ROM?
