Ryzen 7 9800x3d High CPU Usage Issue on 1920x1080 165Hz Monitor

Hi everyone,
I'm facing a strange issue with my system and would greatly appreciate your insights and suggestions. Here's my setup and the problem I'm experiencing:

System Specs:

  • Processor: AMD Ryzen 7 9800X3D
  • GPU: EVGA RTX 3080
  • Monitor: 1920x1080 165Hz
  • Motherboard: MSI MPG X870E Pro Carbon Wi-Fi
  • RAM: G.Skill DDR5 64GB (2x32GB) 6000 MHz
  • Cooling: Cooler Master MasterLiquid ML360

The Issue:

  • When gaming on my 1920x1080 165Hz monitor, my CPU usage stays around 80-90%.
  • When I lower the monitor's refresh rate to 60Hz, CPU usage drops to 30-40%.
  • Interestingly, when I connect a second monitor (4K, 60Hz), the CPU usage also drops to 30-40%, even with the 165Hz monitor still connected.

What I've Tried:

  1. Enabled G-Sync and V-Sync.
  2. Set a 165 FPS limit.
  3. Updated NVIDIA drivers.
  4. Increased graphic settings to shift the load to the GPU.
  5. Reduced the monitor's refresh rate to 120Hz, but the issue persists.

Questions:

  • What could be causing this behavior?
  • Has anyone else experienced a similar issue?
  • Any suggestions or solutions are greatly appreciated!

This format is clear and professional, making it easier for others to understand your issue and provide effective solutions. Good luck on the forums!

Title: Ryzen 7 9800X3D High Temperature and CPU Usage Issue - Solution

Hello everyone,

I previously shared a post about the high temperature and inconsistent CPU usage issues I was experiencing with my Ryzen 7 9800X3D processor. After extensive testing and research, I was able to resolve the problem, and I wanted to share my solution here to help anyone else who might be facing a similar situation.

Problem Recap:

  1. High CPU Temperatures:
    • Under load, the CPU temperature would often reach 95°C, even with a high-quality cooling system.
  2. Inconsistent CPU Usage:
    • CPU usage varied drastically depending on FPS limits in games, with higher FPS settings causing higher CPU usage and heat.

Solution: Curve Optimizer Adjustment

The solution lies in using AMD's Curve Optimizer in the Ryzen Master software or directly in the BIOS. Here's what I did:

Step-by-Step Guide:

  1. Open Ryzen Master:
    • If you prefer BIOS, go to the BIOS settings and find the "Curve Optimizer" option under advanced CPU settings.
  2. Enable Curve Optimizer:
    • Switch it to "All Cores" mode.
  3. Set the Negative Offset:
    • I set the offset value to -30 for all cores. This adjustment reduces the voltage for the processor dynamically, helping to lower heat output without impacting performance.
  4. Apply and Save Settings:
    • Save the configuration and reboot your system.

Results After Applying the Curve Optimizer:

  1. Significant Temperature Reduction:
    • CPU temperature under heavy load (100% usage) dropped from 95°C to around 75°C.
  2. Stable Performance:
    • No performance degradation was observed. The CPU maintained its peak speeds and delivered consistent gaming and application performance.

Things to Note:

  • Your System May Vary: Not all CPUs are the same. Start with a smaller negative offset, like -10 or -20, and gradually adjust to see what works for your system.
  • Monitor Stability: After applying these settings, run stress tests like Cinebench or Prime95 to ensure stability.
  • Cooling System: Ensure your cooling solution is properly installed and functioning well. My results were achieved with a Cooler Master MasterLiquid ML360 AIO.

I hope this helps anyone else experiencing similar issues! If you have questions or need further clarification, feel free to ask.

Cheers,
Kaan

Hi,

Hmm... i dont own R7 9800X3D chip im waiting for the 9950X3D to launch anyways... i think you need to change ur 1080p monitor to at least 2K monitor (is just a theory) but before doing that try to update ur motherboard BIOS to the latest version maybe that will fix the cpu usage

Thank you for your response! I appreciate your help and wanted to clarify the issue further. I’ve recorded a video showcasing the problem I’m experiencing with my 1920x1080 165Hz monitor.

In the video, you can see how CPU usage decreases significantly when switching to 60Hz, while it remains extremely high at 165Hz, even with an FPS limit. I’d like to hear your thoughts on this and if you have any additional suggestions.

Here’s the link to the video: https://www.youtube.com/watch?v=vnmKadQbAW4

Thanks again for your time and support!

Diocenes, why do you think this is an issue? Microsoft has not figured out how to deal with usage for a multiple core processor. Use Ryzen Master (RM) to see what is really happening. John.

Diocenes, post screenshots of Ryzen Master (RM) at both frame rates. Movies are not needed. Again why do you think CPU utilization is a problem? John.

While troubleshooting some performance issues, I observed significantly different results when X3D Game Mode is enabled and disabled. I would like to share my findings and get your thoughts or suggestions on the following:

 

Observations:

  1. When X3D Game Mode is Enabled:

    • CPU usage is around 80-90%.
    • CPU temperature remains stable at 70°C.
    • Graphics settings are maxed out, and refresh rate is locked to 165Hz.

  2. When X3D Game Mode is Disabled:

    • CPU usage drops to around 40-50%.
    • However, CPU temperature rises significantly to around 80-90°C.
    • Graphics settings and refresh rate are the same: max settings and 165Hz.

  3. When Refresh Rate is Reduced to 60Hz:

    • With X3D Game Mode enabled: CPU usage drops significantly to 40-50%, and the CPU temperature stays stable at 70°C.
    • With X3D Game Mode disabled: The temperature still increases even though CPU usage remains low.

Questions I’m Struggling With:

  1. Why does CPU temperature increase when X3D Game Mode is disabled, even though CPU usage is lower?
  2. What causes the CPU usage to drop significantly when X3D Game Mode is enabled and the refresh rate is reduced to 60Hz? Could this be related to specific technologies or optimizations?
  3. What could be the underlying reason for such a big difference in behavior when X3D Game Mode is toggled on or off?

I would greatly appreciate any insights or suggestions you might have. If anyone has experienced something similar or has a better understanding of how X3D Game Mode affects performance, I’d love to hear your thoughts!

Diocenes, I would appreciate the screenshots of RM I requested.

Game mode in RM turns off half the cores, so yes it will lower temperature. A screenshot of RM will show half the cores are Sleeping. Please post the screenshots. John.

Hi! Sorry for bumping, but you are not alone. 

I also have a 9800x3d and Gigabyte B650m Aorus Elite AX ICE motherboard paired with a Gigabyte Aero 4090. 
I noticed when X3D mode is enabled, my CPU (Black Ops, Warzone) is hitting atleast 80-90% usage. 

I have a 1440p monitor with mixed settings in game.

Have you resolved this kind of issue? 

Thanks!

My 9800x3d has never even broke 80c in any benchmark, for more or less any amount of time, and certainly not any game, (why i bought and use a stacked cache chip). 

I dont use curve optimizer. I see zero reason (unless you care about benchmarks only).

 Cant wait to replace my other 7800x3d. I love this chip, and its what the 7800x3d should have been off rip. 

X3D mode, seems like its for a 16 core chip. Not a 8.  But hey, you all do you.  Im loving this thing. Not seeing any of the problems or issues above. None. Zero crashes, issues, anything.

The "solution" isnt curve optimizer lol......   Not sure why the resolution, or monitor hz would matter. In the least to even bring up. 

EDIT- Zero "curve optimizer" here. Does nothing to little in gaming, aka why you bought the chip. This chip runs awesome out of the box.

I dunno, the thing pulling 123w on average for 9 mins straight, , seeing 70c seems ok to me.
