One workaround is to quit the app and stay connected and then launch it, minimize by not moving the cursor over the window. I have sent an e-mail to NordVPN and they still have not gotten back after almost a week. I get that it is a holiday season, but man, why do companies break products right before the holiday season?
I took a look and I’m seeing the following:
Highest measured interupt: 877 microseconds
Highest ISR Routine Execution: 1007 microseconds - HDAudBus.sys
Highest DPC Routine Execution: 1739 microseconds- nvlddmkm.sys Nvidia Kernal Driver
I don’t have one plugged in.
I quit the NordVPN app in the middle of it and my computer sprung back to life from the “drunkeness”
If you look further down OP’s problem has been resolved. You are right, there is no reason we should have gone that far for a simple app. In another post you mentioned having a Ryzen CPU and I’d wager the solution is the same as the OP’s.
Shouldn’t be giving people instructions to messing around with their machines; however those symptoms are similar to when I installed a SoundBlasterX G6. Waited for it, and paid for it so I’ll be damned if it don’t work so I troubleshot it and went with raising the VDDG IOD voltage.
Enough of story time. You should probably get a refund/stop using the app. OP was willing to work with me so I helped them, that’s all.
Was that ran when the VPN was active? Not the best numbers but I don’t believe it should be causing issues. Not at my PC to compare. Setting your PCIE Gen to GEN 3 in the BIOS is the simplest way to determine if its a stressed IOD. My next step would be memory/RAM configuration.
Yes it was. I just went into BIOS and swapped the PCIE from auto to GEN3 so we’ll see. Could you explain what you mean by stressed IOD?
The IOD die on the Ryzen processors houses your PCIE lanes, memory controller, and some other components I forgot. By “stressed” I mean there is insufficient voltage for the IOD die to service all the components and it tends to behave poorly as a result.
Using PCIE Gen 3 may impact (even if miniscule) performance of your GPU and NVMe devices which is why the better option is to adjust VDDG IOD voltage. All of this is beyond the scope of this subreddit though.
interesting. You’ve gone above and beyond my scope of knowledge, but I really appreciate the help. It seems to be running better for now. I also went and updated the Realtek drivers since those were also showing high latency, but now they seem okay.
If I have the option to run in GEN 4 on my BIOS would that not be better? If not what is being on GEN 3 do in this scenario?
GEN3 has lower bandwidth limits, as a result there is less pressure/demand on the IOD die. To see the performance loss on your 4090 you can type in “Nvidia RTX 4090 PCIE scaling” or something similar.
To run GEN 4 you’ll need to configure your voltages (VDDG CCD/IOD) manually because Auto does not supply enough for your workload. Configuring that puts us at r/overclocking
That’s for another day. Thanks for all of your help! Happy Holidays!
