After setting up my new system I decided to undervolt my GPU, as I had done before on my old one. Interestingly enough, I seem to be able to undervolt my GPU more on my new board, than on my last one. On my last board, anything smaller than -20mV resulted in artifacts, but now I am able to push it down to -35mV without any problem - I will continue to push it down to see how far I can go.
Still, it is interesting that my mainboard is a contributing factor, because I believed this was solely dependant on the GPU.

What components do you use? Mainboard/GPU/OS?
oh sure - that would have been interesting as well:
Old PC:
Windows 10
ASRock z68 Pro3
i5 2500K
850W PSU (gold +)
MSI r9 390 oc
New PC:
Windows 10
ASRock X370 Taichi
7 1700X
1000W PSU (gold+)
MSI r9 390oc
Sweet Ryzen Rig! Nice!
And you do the undervolting in the OS or the BIOS? I played with undervolting years ago and i gotta say, i do wanna try that again.
Or do you modify the Firmware of the GPU?

Do you think that possibly the 20 degree offset on the R7 1800X and 1700X has an impact here?
I'm not sure if the 20° offset of the CPU could have an influence on the GPU, I strongly assume it is the mainboard. However, I'm not sure.
Possibly it's because it just has better voltage regulation so it can create a steadier current for devices outside their normal operating ranges than your last Mobo.
