Got myself an ASUS ROG Strix Vega 56 today. However, when the gpu is at idle (clock speed is low) I have horrible DPC latency. Mouse skipping/lagging, sound popping/cracking and all kinds of issues... When I start a game it works as intended.
I discovered that if I set the memory clock to say 700 mhz (state 2) on wattman, there is no issue. However, when the memory idles back to 167 mhz, I get that dpc latency... I can also workaround the issue by setting GPU clock to something higher than idle clocks...
Is this a defective card or a driver/software issue?
Here are screenshots from latencymon when the card is idle:

My specs are
Ryzen 1700
Corsair Vengeance LPX DDR4 3200 16 GB
Asus Crosshair VI Hero X370
Corsair HX850i
Windows 10 Pro x64 Update 1809 (also tried 1803, no luck)
I got two monitors by the way, ( 60 hz + 144 hz Freesync)
Thanks in advance.
