How do you force an amd gpu to always be at one voltage?

[Terry Tuna]

Afterburner CTRL+L doesn't seem to work.
And I need to do this to see if my gpu will work fine like that, since when its under a certain voltage/frequency - most apps start glitching out.
Using a MSI r9 390 8gb, drivers - latest (default windows drivers do work without doing this kinda stuff)

Seems like the VRAM is dying to me.

Not a memory ic issue though, at least not one you can see with a OCCT (although if there's better tools to check that kinda stuff - tell me), unless I am being a moron, which is likely.

Force Constant Voltage in MSI Afterburner settings couldn't work?

Don't think it does, unless I'm doing something wrong.
Pressing CTRL+L in the voltage/frequency curve editor does absolutely nothing (I did click on the voltages), if that's the way you force the voltage to be constant.

Might only force constant voltage on GPU.

It's in the settings of the program. I think the first tab that appears.

It was on while I was writing the first post, the voltage seems to jump from 914 to 1133, which could be normal, but I dunno.
The main problem I have atm (excluding the whole thing with the gpu artifacts) is the fact that the whole "yellow line will appear if you press CTRL+L in Voltage/Frequency curve editor while also highlighting the required voltage" doesn't seem to do absolutely anything.
The screenshot is old, but the issue persists on every driver I tried (which is around every each one on the AMD support page), except for the default windows ones.

I think that option only works on Nvidia Pascal and Turing GPU.

 

I don't know if Radeon Settings frequency curve works for r9-390, did you try?

Going to be a pretty hard task considering this: https://gyazo.com/11d2f2aee206fa21271f59ef361a9020
Will try though.

Welp, no can do, https://gyazo.com/f3a05cb42ac8b9de00ed997e9ad0e724
The core clock speeds seem to jump from 600~ to 900~ constantly, is that a sign to something real bad? Never noticed it happening before, 
afterburner is off.

Oh... lmao. 

 

Furmark is trash, try Unigine Valley or Superposition. Your core clock fluctuating because it probably hitting power limit or BIOS safety kicks in because again, Furmark is trash.

Issues in DirectX 11, no issues in DirectX 9.

After ending the DirectX 11(ultra settings + 2x MSAA) benchmark I got a score of 2300~ , if that matters in any way.
UPD: Actually, no issues if it's running windowed, weird, but the radeon adrenalin app still doesn't work https://gyazo.com/31c616a7f625296c8d180a2bee5766f8
