I have seen the discussions on Vdroop settings / options on the Z390 Dark boards. That platform has a range of settings wheres the X299 Dark has either Enabled or Disabled.
 
Is this a limitation of the X299 chipset / CPU architecture or is this just a feature that has not been pushed to the X299 Dark?

    X299 DARK was designed earlier and didn't have this function implemented at release. Secondary reason for that - VCCIN input rail is less sensitive to voltage variations, because motherboard does not provide power directly to CPU Cores (like on little socket), but to FIVR on CPU package instead. So I take loadline on X299 VCCIN rail bit less important than it is on little sockets. And CPU on X299 to which this would matter more is now EOL (KBL-X).
     
    I'll test additional options (VRM on both boards is nearly identical) and hopefully BIOS guru's will add this into upcoming X299 DARK BIOS versions.

    If you have question, please post in public forum. I do not reply PMs, so all in community can benefit the answer.

    Thank you for the input TiN_EE
     
    For the time being I have been running with it disabled.
    I saw it mentioned in the Z390 Dark section that it helped with Temps (to what degree, who knows) having it enabled. I went and looked at what options I had and that is what brought up this question.
