You are directing your question to the wrong company. Intel is who you should be talking to...won't do you any good though, as they make it clear the motherboard does not meet the requirements for Win10 and haven't supported it in years. I have the DX58SO and am completely happy with Win7.
Thanks for your reply kingfish. Any attention to the issue is welcomed.
I don't fully agree with you though. My X58 board ran absolutely fine under Win10 when I still had my R9 390. The Windows 10 compatibility checker reports 100% OK. Having official active support and being compatible are separate things in my opinion.
I could downgrade even further towards an older chipset, in which the Vega runs fine again under Win10, but that's just silly.
I do recognize the fact that the X58/Z68/.. platforms really are old and running one of the world's most powerful GPU's in such would seem odd. However, as most tech-Tubers are agreeing with, is that these are still very powerful and offer an insane performance to cost ratio, hence the user base still.
I could do, like many others have done in this situation, switch to the competitor's side where all is fine in this regard, but I'm still a too big fan to take that step myself.
