If you want to keep the performance you have to increase the PL. On Vega, lowering the core voltage has - at some point - the side effect of bringing down the effective boost clock. So to keep a stable 1630 MHz on average at 1010 mV you'd have to set a much higher frequency (which in turn uses...
The clocks jumping around is usually due to running into the power limit. Either raise that (from 180W default on the Pulse) and/or try to undervolt the card manually. It could also happen to be that the game is occasionally CPU or I/O bound and allows the GPU time to clock down.
Temps are fine...
I agree, screen width is more important than pixel density for immersion. I noticed that when I replaced a 768p 32" TV with a 1080p 27" monitor.
What I never fully understood about Vega is the memory voltage floor. I tried figuring out the exact stable core frequencies for different core...
Another Pulse owner here:
Power Limit: 180W (stock)
Core: P7 = 1640 MHz @ 1010 mV / P4 = 1336 MHz @ 860 mV
Mem: 880 MHz @ some lower voltage
For the memory clock and voltage I used OverrideNTool and its soft power play table editor, because when I use Radeon Settings it was always dropping mem...
Oh and big thanks to whoever explained how the HBM clock works. I naively set the core states 6 and 7 to 932 mV and 1030 mV respectively, and wondered why the HBM clock wasn't going beyond 500 MHz in many instances. Today I learned that the HBM voltage needs to be reduced to that of the lowest...
I hope I never need to replace the cooler on any graphics card. From what I've seen in videos I'd probably pull my hair out. Good that it worked for you eventually.
What I was a bit surprised with reading this thread, is a couple of people reporting hot spot temps over 100°C and pretty large...
