P53 RTX 4000 throttling

2019-11-18, 21:34 PM

My P53 has been having some issues since BIOS 1.16, and it has continued in ver. 1.17. 

 

The GPU will throttle down to ~25% clocks and consume no more than 40 watts. Ive tried using the Quadro drivers that came with the system, as well as the Quadro experience beta drivers from nVidia. The drivers had no effect. 

 

The problem occurs pretty much always when on battery, regardless of the power mode and driver settings. 

 

It occurs seemingly at random when on wall power, and sometimes will happen when in the middle of GPU intensive work, or when switching from an iGPU app (word or chrome) to a dGPU app (solidworks, etc). 

 

Restarting does not fix it. I tried reinstalling both drivers as well, and it didn't fix it. The problem does not seem to be a thermal constraint. 

 

 

My current theorey is that there is something wrong in the BIOS since the version mine shipped with didn't have this issue, but 1.16 and 1.17 have it. As far as I know, there is not a way to roll my BIOS back. This would imply it is software, and not hardware.

Another thing to note is that the CPU does not throttle at all (i7 9850H).

You can roll back you bios. I did it before when searching for the route of my performance issues. 

 

The earliest you can roll back is 1.14. There is a bios setting that you have to enable. If you can wait a bit, I'm about to repast my cpu & gpu, after that I will tell you exactly where that setting is (if no else does before).

 

Last thing, I think the gpu is limited in every bios on battery. Though I could be wrong.

If you set the performance slider (under the battery icon) to maximum performance, the battery will not limit the GPU. Also, there is a setting in the BIOS for performance under the battery as well as in the Intelligent Power Plan.

The dGPU throttling sounds like an NVIDIA driver issue., especially since you state that it is not a thermal issue so it must be tne power state of the dGPU.

I wonder how widespread this problem is? My recommendation for P53/73 owners w/ Quadro RTX is to check their Memory Clock speeds using TechPowerUp GPU-Z

 

I hope this helps others identify GPU performance issues.

Did this BIOS rollback solve your problem? 

 

Id prefer to try driver-side issues before going back to older BIOSes. 

 

As for GPU mem clocks, that is part of the issue, but it also will clock the core frequencey down in a similar way.

No - the BIOS did not solve it for me. I also went back to hybrid mode, and it still throttled on the Nvidia Quadro RTX. If I set to 'Turn off display' in Power settings to 1 min, I can usually replicate the throttling.

If that replicates it, it persists accross BIOSes, and between different cards, its certainly something on nVidia's driver. 

 

Lenovo needs to get in touch with them about fixing this. 

 

I read on the r/thinkpad sub that people had luck by forcing geforce RTX drivers corresponding to their card (rtx3000=2060, 4000=2070, 5000=2080), but I really dont want to do that as geforce drivers have their own set of issues inherently.

One of Nvidia's older drivers 436.30 seemed to recover more consistently than the others after 'Turn off display' but Throttling comes back just when I think it's fixed for good.

I did try one of the Geforce RTX 20 series and seemed to install fine. Throttling happened on occasion, but after yet another OS Reset, would rather not introduce yet another variable.

For a mobile workstation, I expected a lot more performance and stability. I wonder if other PC manufacturers are experiencing these issues? I feel for software vendors who are probably getting the blame when it's likely hardware and/or drivers.
