Question Frequency and FPS drop, stuttering on RX 480

Hi. I have problem with stuttering. Everything can be seen on the video. In a nutshell, i have fps drop because gpu downclocking core after reaching 150W, in EVERY
game. Temperature graphics card, VRM, CPU normal. I slide power limit in Wattmann to +50%. I reinstall windows, install newest driver. I don't know what else I can say, this is a very troublesome problem.
MSI RX 480 4GB Gaming X
I5 6600k stock
ASUS z170-p
8GB RAM 2400mhz
OCZ Stealthxstream 2 500w

EDIT: ANY PROGRAM FOR TESTING GPU LIKE FURMARK for 10 sec RESETs PC

I have an MSI RX480 GamingX 8GB.

Try this: Go into AMD Settings, Performance tab, Tuning sub-tab.
  • Set "tuning control" to manual
  • Enable "gpu tuning"
  • Enable "advanced control"
  • (Assuming your frequency states are the same as mine) Set the following voltages for each frequency:
    • 300MHz / 800mV
    • 610MHz/ 818mV
    • 910MHz / 870mV
    • 1075MHz / 910mV
    • 1145MHz / 930mV
    • 1190MHz / 945mV
    • 1235MHz / 970mV
    • 1305MHz / 1040mV
  • Enable "VRAM Tuning"
  • Leave Memory Timing on "automatic"
  • Enable "advanced control"
  • (this may vary for you since my 8GB card runs 2000MHz VRAM (8000MHz effective), but set Voltage to Manual and enter 950mV. That should be plenty for your 1750MHz VRAM.
  • You can click the three dots in the top right corner and "save profile" so you don't have to re-enter these values if you get a driver crash or something.
I've generally found those voltages to be stable for most cards, but if you get frequent driver crashes, let me know and I can help troubleshoot.

This settings crashed games after sec and resets wattmann to default settings, increase mV?
EDIT:eek:kay, I've increased mV by 10 until it reached this voltage
  • 300MHz / 800mV
  • 610MHz/ 818mV
  • 910MHz / 870mV
  • 1075MHz / 930mV
  • 1145MHz / 960mV
  • 1190MHz / 975mV
  • 1235MHz / 1000mV
  • 1305MHz / 1100mV
but still is freezing game and resets wattmann settings

+10-20mV should've been fine. No way it needs +60mV. At those settings you're above stock.

Try going back to the values I had, but increase VRAM voltage to 960mV, then 970mV.

VRAM voltage sets the lowest voltage the GPU will go (to preserve VRAM stability since the core and VRAM get the same voltage).

How'd you hook up the single 6 pin from your PSU to the 8 pin GPU power plug? I'm suspecting that your PSUs 12V x 18A (216W) GPU rail could be causing issues here. Not necessarily for average power draw, but for the brief peaks.

Does the situation improve if you set both states 6 & 7 to 1235MHz / 970mV?
