RX 5700 XT fluctuating clock speeds

Hello,

I'm getting clock speeds issue on my RX 5700 XT Pulse.

My GPU settings (undervolt/overclock) (was stable and issueless):

  • Core: 2000MHz (actual 1930-1940MHz)
  • Core Voltage: 1080mv
  • Memory: 910MHz (actual 1820MHz)
  • Power limit: 0%

Problem description:

  • If I have custom settings set in AMD Wattman I'm reaching 99% usage (which is normal = no vsync) but not getting to factory clocks.
  • GPU is reaching clocks between 1600-1640MHz on Core and Memory clocks are sometimes jumping from 875MHz to mentioned 910MHz.
  • If I put Power limit to 50% which kinda solves my issue but I was able to run that settings mentioned above without any touch on Power limit.

When it happend:

  • Yesterday when I installed new driver 19.11.1. I DDU it and installed 19.10.1 and still it seems I have the same issue.

My possible solutions for it:

  • Drivers (Tried 19.11.1. , 19.10.1 and will try 19.10.2)
  • PCIe settings in BIOS is set to Auto instead of 3.0
  • Shader cache (as I read in similar issue post)
  • High performance set in Windows (Power options)
  • Let me know what you think the case might be.

Thank you for your help and time.

Re: RX 5700 XT fluctuating clock speeds

It's "normal" I guess, with the same thing happens. It's just a power saving feature from AMD,... 

Never had my boost speed of 2035 mhz, my card is 4 days old,... Maximum so far is 1930Mhz but only just a few seconds. None of my other system components get used 100% so I do not have a bottleneck. 

You should complain to AMD about it and also your custom card maker, ask them for a specific game profile driver option that disables power saving so the card runs stock speed minimum or higher,...  

Nividia has this, I never had problems with FPS drops due to low frequency and fluctuations with Nvidia,...

Re: RX 5700 XT fluctuating clock speeds

So if I write them they will give me what? Custom BIOS or guide to disable it? But if they will give me guide on how to disable it why there is none guide on the internet? Sorry if I sound dumb but I don't get it. I understand they have some power savings within the software itself but why I don't have the option do disable it. Thank you

Re: RX 5700 XT fluctuating clock speeds

Yeah that's the point, there is no option,... 

You have to report that it's malfunctioning so they know something is wrong and ask them for the option to disable this,...

Here on the forum there are just normal people, they do not work for AMD,...

Re: RX 5700 XT fluctuating clock speeds

That's dumb that they are hiding options which some people may want to disable. I had NVIDIA and it was kind of weird that I'm missing power saving option, RX 5700 XT is my first gpu from AMD

Re: RX 5700 XT fluctuating clock speeds

Indeed, I also switched to a AMD GPU just 4 days ago because of better performance/quality/price. Sadly now there are driver issues,... 

Just report it,... It's a simple solution,...

Re: RX 5700 XT fluctuating clock speeds

Update: Fluctuating isn't problem anymore it was fixed by installing 19.11.1. it was due to driver 19.9.2. which created my issue mentioned above.

About power option settings: So I spoke with a guy from Sapphire about my problem and he told me that GPU power saving is controlled by OS not GPU itself. I am still in contact with him but I want to if I should contact AMD support or if it's true what he said, seems weird to me that OS is controlling GPU power savings.

Re: RX 5700 XT fluctuating clock speeds

I do not see what harm it can bring to contact AMD,... 

The driver works on Windows so maybe windows is not properly working with the driver, maybe that's what the guy meant. Eitherway it's their responsibility to make it work,...

I reported my problems and they are looking into it (asus) and AMD itself thanked my for my feedback and told me to wait for the next driver so I assume it's a driver problem.

Re: RX 5700 XT fluctuating clock speeds

I will contact AMD but don't know how or where.

About the driver: the guy from Sapphire told me that power savings on GPU are controlled by OS so there is no option, I actually don't understand what you mean by "driver problem".

What issue did you report to the AMD support and what answer you got from him.

Well there is no point telling you about my problems again and explaining,... 

If you do not have any problems with your GPU anymore of course you do not need to contact AMD,...
