Re: GPU Problem: ThinkPad P73 with Quadro RTX 5000, 6c Xeon, 32GB ECC

Lenovo Vantage offers nothing really, it a gimmick; I have cause I like blue L icon on speed bar;

And it is behind on updates too quite often ... BIOS updates for example;

As far as your issue goes i suggest you sit on the phone and go hard on them; They should do return / exchange if this is only few days over; It is still under warranty; Mention forum, say you were trying to address issue. People were successfully getting an exchange under much less favorable premise

Re: GPU Problem: ThinkPad P73 with Quadro RTX 5000, 6c Xeon, 32GB ECC

So after some more messing around and trying odd different combinations of the drivers installed, it seems like the temp sensor in GPU-z is no longer reporting temperatures above 45*C, and is occasionally flashes to 0*C. It seems that the GPU clock speed is no longer locked to 300 Mhz, but the GPU memory speed is *still* locked at about 200 Mhz. I think I will try to install an alternate graphics driver and if nothing else works I might try to call Lenovo and ask if they'll accept a return a few days over their deadline.

This looks like a different issue all together.

If a sensor is faulty then such behaviour is to be expected. I doubt it is a userland software issue too, vbios/bios maybe.

 

You do have most recent BIOS right? Do not rely on Vantage, hand check ....

 

Good luck

Re: GPU Problem: ThinkPad P73 with Quadro RTX 5000, 6c Xeon, 32GB ECC

For those who are interested, I was able to solve the problems on my P53, as outlined in my post in this thread:

Thanks again to agazpp and FreedomReapr for the help!

I'm glad you were able to solve the problem! It's frustrating when receiving new machine and you start having issues that shouldn't be happening in the first place much less straight from the factory. Thanks for keeping us posted!

Can anyone share the P73 vbios?

Re: GPU Problem: ThinkPad P73 with Quadro RTX 5000, 6c Xeon, 32GB ECC

So I've discovered something new... While formatting and reinstalling Windows solved the 300mhz lock on the RTX 5000, the issue still exists on battery. Can anyone else still here confirm this? It may be a power issue as the machine is running on battery. Once plugged in the problem dissappears. It feels exactly how it used to before the issue resolved when on battery power. When running any benchmark the GPU enters limp mode...

As far as I know, this is an expected behavior for RTX cards while on battery;

I did not go deeply into the matter though;

Re: GPU Problem: ThinkPad P73 with Quadro RTX 5000, 6c Xeon, 32GB ECC

That's what I was thinking... i wouldnt use intensive programs on battery anyways. These machines are meant to be plugged in. Thanks for the reply!

Re: GPU Problem: ThinkPad P73 with Quadro RTX 5000, 6c Xeon, 32GB ECC

Throttling speeds seem to be the same as Battery mode speeds where the memory clock is locked at a low speed while the GPU clock doesnt seem throttled at all. I think the either Lenovo or Nvidia should provide some factual numbers so that real issues aren't as easily dismissed. 

 

At one point, I uninstalled Microsoft ACPI-Compliant Control Method Battery from device manager and the GPU was going full speed. I didn't let it stay there long - the intent really was to make sure nothing was wrong with the battery driver.

And we're back...
