Low FPS with new GPU & PSU

Just put in a new GPU and PSU today. Frames in games have been lower than what they used to be; even browsing Netflix feels stuttery. I double checked that my monitors are plugged into the GPU (Primary monitor uses the DVI-D cable) and that the GPU is using all 16 pins. I have tried running DDU and doing fresh installations of drivers, but the problem is still there. Tried an older driver, no change.

CPU: AMD Ryzen 7 1700
Mobo: Gigabyte AB350-Gaming 3
GPU: GeForce GTX 1080
PSU: EVGA SuperNOVA 750 G2, 750W
RAM: 16GB
OS: Windows 10 x64

When I ran the games, the temp is sitting at 60C (in-game settings are the same as before). I've tried everything I could find and I'm running out of ideas. All I can possibly think of right now is that I messed up somewhere putting everything together (I'm fairly new at this).

I'm not sure what other info is needed but I'd be happy to provide them. Thanks in advance!

  1. What is your cpu temp while gaming? People have dislodged cpu coolers while installing new parts.

    What is your cpu (each core) & gpu average usage while gaming?

    What games, settings, resolution and fps are you running?

    I'm not sure how to pull the log, so I hope the screenshot would do! The game settings are all on Low (No antialiasing/Vsync/post-processing), running DirectX11. These are the same settings I ran before with my GTX 760, and I had similar performance with it which doesn't make sense to me.

  3. Because you've done everything right this is a hard one. There's no reason why you shouldn't be seeing massive gaines over the 760.

    When you can, run 3d mark firestrike and we'll compare your score.

  4. Yeah I see no obvious reason for this

    Just ran Firestrike, here's the result.

  6. Thanks, can you provide a link to your results page as well so we can look at it in depth like clock rates for your gpu and cpu

    Of course.

    It seems according to 3dmark your score is reasonable and near to others with similar system give or take a couple thousand, keeping in mind differing clock speeds with gpu and cpu.

    One thing i did notice is your cpu's turbo isn't reaching full potential. I wondering if your cpu is holding you back. Something doesn't look right there.

    Are your windows power plans set to max? Gpu as well?

    Yes, both are set to max performance. It's gotten to the point where scrolling in my browser (Firefox and Chrome) visibly lags as well, which rarely happened with my old GPU.

  10. See what sizzling reckons.

    Things you could probably try

    Boot Windows diagnostics startup in msconfig to limit startup programs. Type msconfig in windows search bar.

    Test your old card, see if the problem still exists indicating something else os related.

    If you have a spare hdd, maybe try install fresh Windows. Disconnect your ssd first if you try reinstallng on another hdd

    Check all connections and power leads inside the computer case for any loose connections.

  11. I went into my BIOS to manually change the clock ratio for my CPU, and now the problem is gone. I don’t know how it made such a huge difference going from 3.1Ghz to 3.7Ghz, but it seems to have solved the problem. Thanks for catching it!!
