PC Drivers & Software

[Woodiii]

Hello,
I bought an ASUS ROG Strix LC AMD Radeon RX 6900 XT 16G OC Edition (https://www.amazon.de/-/en/gp/product/B08CVBC5MG/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1) 3 weeks ago.
My PC is built as follows:
- ASUS B350 PC-MATE (Mainboard)
- AMD Ryzen 7 5700G (CPU)
- Corsair Vengeance LPX 32GB (2 x 16 GB) DDR4 3200MHz (RAM)
- 2 SSD's and 2 HDD's

I downloaded the recommended drivers for my card from the product website. The revision number is: Adrenalin 22.5.1 Recommended (WHQL)

So now to the problem:
The card works fine 95% of the time. 120+ FPS with 4K and Ultra settings in PUBG and 80 FPS in ARK. However, from time to time the FPS drop to ~10 for 10-30 seconds. I then once had the performance monitor open in the AMD driver software on the second screen. And when I experience these laggs, the card utilization drops to 5-10%. The temperature is stable at 60 degrees GPU core and max 80 degrees GPU hot spot. I think it is because of the drivers. I also sometimes experience a short flicker on the monitor which is attached to the graphics card. This only a little bit annoying, but with my old NVIDIA GTX 1070, I never expierienced these kind of problems.

Do any of you have a suggested solution?

It's possible that your gfx card falls into idle mode from time to time. You can test what happens if you create a game-specific profile and set the min frequency 5-10% lower than the max frequency.

How can I prevent it from falling into idle mode?

[Paan]

Add a game profile, tune in performance, set the frequencies 5-10% from max frequency. Or u can find in youtube how to set the gpu clocks.

[schldskjoirz]

1. Open Adrenalin
2. Select 'Gaming' from the menu bar
3. Select desired game from the list of installed games
- If for some reason the game doesn't appear in the list of installed games, then click the three-dot button ('More Options') on the right-hand side and select
'add game'. Find the game you want and click 'OK'. It should then appear in the list.
4. Select 'Tune Game Performance' next to the 'Launch Game' button
5. Enable 'Gpu Tuning'
6. Enable 'Advanced Control'
7. The 'Max Frequency' slider should already be set to the maximum of the graphics card. Slide the 'Min Frequency' slider near the max. For example my 6900XT's min frequency is set to 2300 Mhz
8. Enable 'Power Tuning' and adjust the slider to 15%
9. Click 'Apply Changes' button and you should be good to go.

Hopefully this fixes the problem.

Hello,

I've configured it just as you said for PUBG, but when I want to start the game it crashes and AMD Bug Report Tool tells me, that: "AMD software detected a driver timeout has occured on your system.". So yeah, I don't know what to do.

[schldskjoirz]

I think at this point you should install the 22.11.1 version to see if it fixes the problem. Better to do all possible software exclusions and then if nothing works, you can start suspecting a hardware problem.

By maximum GPU frequency he meant default value, not literal maximum.

Just set min frequency to -100 from max one. (Like my maximum is 2950 and it is unstable, but default value is 2659.

So for my config i need to set up min=2559, max=2659.

If this is still unstable, try lowering max and min clock by about 100-200 mHz... Even though it shouldn't be unstable

There is another way with MorePowerTool. Disabling DS_GFXCLK and GFXOFF features. If you are interested you can google this program yourself (it is from igorslab)

If there is still persisting issue after that, you are likely have either hardware or software incompatability, or configuration issue. Or application/configuration conflict.

[Woodiii]

I've set it up like you and it is better, but the utilization still drops sometimes for 10 seconds. What do you mean with 'likely have either hardware or software incompatability'?

What is your monitor setup?

Monitors, their number, their refresh rate and their connection type to GPU

[Woodiii]

My primary monitor is a 4k@60Hz Monitor connected via HDMI to my RX 6900 XT.

My second monitor is a 1920x1080@60Hz Monitor connected via VGA to my internal graphics chip on my cpu.

I have to do this, because the graphics card only has one HDMI outlet and i need to connect the main monitor via HDMI in order to use 4k@60Hz in Linux, because with Display Port, Linux wont run 4k@60Hz, only 4k@30hz...

So should I buy a HDMI to Display Port Cable for my second monitor as it has only one vga and one hdmi outlet.

I have to do this, because the graphics card only has one HDMI outlet and i need to connect the main monitor via HDMI in order to use 4k@60Hz in Linux, because with Display Port, Linux wont run 4k@60Hz, only 4k@30hz...

Are you... don't know... should be able to install display output drivers on Linux? It should support DP output with normal speeds.
On other side, DP to HDMI might help. As you use 2 monitors and one is connected to iGPU, it may be that system randomly falls to it. 10 FPS is usually about lowest FPS during lagspike and lasts for a frame. For it to happen for 10-30 consecutive seconds is definitely not normal behaviour. But as it is impossible for me to replicate problem and try to find solution i am carefully saying that it "might" help, as it also "might not".

[Woodiii · Accepted solution]

So, I have now connected my main monitor via Display Port and my second monitor via HDMI to the graphics card and I disabled the internal graphics unit of the cpu. After that the lags have stopped. So thank you for the support and I will mark this topic as solved.

I try to fix the Linux 4k@60Hz Bug or I have to buy a Display Port to HDMI Cable for the second monitor...
