Vega+i7 8700. 4k60hz stopped working?

I've had my hackintosh running with dual monitors for a while, one 1080@72hz and the other 4k60hz with no issues. I had my computer off for a day, come back, boot it up and it's knocked back down to 30hz. I was using the WEG -cdfon bootflag and haven't updated anything. Any ideas why this would stop working? On 10.14.3, clover 4871.
