Problem with jumping Clock Speeds on 390X. Need Help!

post #1 of 35
Thread Starter 
Hello Fellow OCNers.

I have recently bought a Sapphire Nitro 390x and have noticed a strange occurrence. It comes stock clocked at 1080/1500.
Whenever I run a benchmark or a video game, my core speeds jump between 500-1080, and with that my voltage also jumps around. Now this causes a lot of the games to get lower FPS than they should be getting, for example in more intense scenes when the GPU is being used 100% it runs at 1080 speeds and I get higher fps than in much lower intensive scenes where my GPU speed fluctuates and causes what feels like stutter.
Any suggestions as to what I should do?

I have tried forcing constant voltage in afterburner(no luck)
I have tried disabling ULPS(no luck)


Updated: Running 16.1 Crimson and My temps never go above 69-70. Averaging at around 65.
Could it be my PSU?

Its not being temp throttled is it?
Doesn't sound like it if its running better at 100% load then at lighter loads though...

Might help to post what driver version you're running as well.

I've tried reinstalling older drivers, reinstalling new ones. I've tried literally everything. I think it's either the card or my power-supply can't provide a clean enough power current to the card. So, unless someone can help me out, I think I will try to return the card and buy a different brand, and if that card has the same issue than I will try to replace my PSU.

can you show some Screenshot in game from each time you get the max frequency and when it drops?

run with MSI Afterburner OSD in game, and if you can with GPU z on sensor tab

The frequency at which the clocks jumps is to frequent where I couldn't take a screen shot properly. So I'll use some kind of screen capture software to show it to you. Gonna figure it out once I get back from work.
