Also... That's KDE Plasma! You switched from Ubuntu?

 

I did an in-place migration from Ubuntu to Kubuntu.  Turns out that I love KDE...

Heh, told you so. Dolphin is the best file manager I have ever seen, and Konsole is also a decent terminal emulator.

[Aaron44126]

Well, I tried really hard to reproduce this issue "on demand" in Windows on the Precision 7770 and failed.  I was ready to start a new thread about this problem, but before I can do that, I need a hard reproduction case.  It might be that a longer test session is needed, because I generally only run into this issue once or twice during an hour-long game session and it lasts for maybe 20-30 seconds when it happens.  (But that's without pushing the CPU to full tilt, yuzu just pushes 3 or 4 CPU cores pretty hard.)

 

Using the Windows 11 OEM image, I ran 3DMark "Time Spy" in a loop while simultaneously running Cinebench.  The result over several minutes was a pretty constant 110-120W power draw on the GPU (with it complaining about still being power-limited), and Cinebench seemed to be the one suffering from low performance, which is I would argue the appropriate behavior.  The CPU was stuck at 2.05 GHz (as reported by Task Manager), with all 24 threads running, until I ended the 3DMark test.

 

I'm also taking back what I said earlier about a big dropoff between P2 and P3.  I watched the power state while running this test and it was bouncing around between P0, P2, and P3, but performing fine all the while.  I guess I'll revise my statement to be along the lines of "When the GPU is in the poor performance state, it can't go any higher than P3" but that doesn't necessarily mean that P3 is bad under "normal" circumstances.

 

One thing is, I noticed that I had "Enable adaptive C-states for discrete graphics" turned on in the BIOS, which I do not want, so I turned it off before testing.  That could have made a difference.  I know that you (@Ionising_Radiation) also found that turned on, but still had the issue after you turned it off.  I'm not sure how that got toggled on because I have tried to be careful to keep it turned off.  I know that I had tested with it on before and found that it impacted graphics performance for the worse.  I did upgrade the BIOS a few days ago for the first time in a while .....?

 

For kicks, I went and tried turning on "Enable Turbo Boost Maximum Technology 3.0" in the BIOS, because the help text there explicitly states that turning this option on also turns off NVIDIA Dynamic Boost 2.0.  For some reason I thought that this also negatively impacted graphics performance, but I didn't find any meaningful difference when running the same test again, so I'll try with it enabled for a while.

 

[Edit]

Wrote this cheesy script to help me check on this issue under Linux, grabbing CPU power draw, GPU temperature, GPU power draw, GPU P-state, GPU speed, and GPU utilization.  (Took me longer than I thought to find a way to grab the CPU power draw with a terminal command...)  Hoping that if I hit the Linux GPU performance issue again, there will be some kind of indication here (high CPU power draw + low GPU speed) confirming whether or not it is the CPU/GPU fighting each other for power....... or if it is something else entirely?

After 'repasting' (repadding?) with Honeywell PTM7950, temperatures are much better, even with higher power draw:

So... the P3 problem is back. This time I was playing Halo MCC, and I barely noticed it, because the game is so light on the CPU and GPU, that frame-rates went from 240 to 120 FPS. But the GPU's power was cut to P3, and I really have no idea why. I don't know if I should update to the latest BIOS, if that will help. 

[Aaron44126]

I have not had this problem on my system since I disabled “c states for discrete GPU” and also enabled “Intel maximum turbo boost 3.0”, which supposedly disables NVIDIA Dynamic Boost 2.0.

[Ionising_Radiation]

I've tried all combinations of dGPU C-states, Maximum Turbo Boost, the NVIDIA Platform Controllers and Framework being on/off/enabled/disabled, and I still see the problem.

My guess is that it's EC-governed thermal throttling, presented to benchmark/monitoring software as power-limit throttling. Case in point: I was gaming without air-conditioning, and the GPU throttled back down; switched on the air-conditioner, and ten minutes later, throttling went away. So it appears @Etern4l was right after all, it was temperatures, just not enough for the GPU to throttle itself, but enough for the EC to complain...

Does the Precision 7760 support a 2TB WD SN850X? It doesn't seem to work for me. It only fits in 1 of the slots due to the heatsink, but I think this slot is supposed to support Gen 4 drives anyways? It doesn't show up on disk management, WD software or the BIOS. 

 

I kept the bottom cover screwed off and when powering on the laptop I can see that the RGB/power light of the drive doesn't turn on either. It does actually work when using it in an external USB enclosure so I know the SN850X isn't bad. 

[Aaron44126]

Any NVMe drive should work. I’ve used a number of modules in multiple Precision systems and never had an issue. So, not sure what to say here. I have not tried this specific model.

 

I do have an issue with the primary slot in my Precision 7560 (the PCIe4 one) failing to consistently recognize drives, so I don’t use it anymore. It’s still problematic after multiple motherboard replacements.

 

It is expected that drives with a built-in heatsink will not fit. You should use a bare drive and the heatsink included with the system.

I have a WD BLACK SN850X 2TB running in my 7760, I forget which slot, but I don't remember that mine came with a heatsink, I certainly don't remember having any issues fitting it.

New BIOS 1.22.1 for Dell Precision 7560 and 7760

 

Fixes & Enhancements

• This release contains security updates as disclosed in the Dell Security Advisory DSA-2023-113. For more information,    see Dell Security Advisories and Notices.
• Fixed the issue where a yellow exclamation mark is displayed next to NVIDIA Platform Controllers and Framework in Device Manager.
• Fixed the issue where the system does not boot into the Preboot Execution Environment (PXE) from the Dell Dock WD19S. This issue occurs when you disable the Enable USB Boot Support option in the BIOS setup.

 

So finally NVIDIA Platform Controllers and Framework case is closed and Intel Turbo Boost Maximum Technology 3.0 setting is removed from BIOS for ever.

 

 

[Rinconmike]

So I previously disabled the turbo boost 3 in bios to get rid of the exclamation mark. Should I reenable before updating to this bios?

I think the BIOS update effectively disabled that option and removes the option to enable it again, so you should be fine if you already have it disabled; it will be basically no change for you.

Yep; the option is completely gone.

BIOS update warning.

The nvpcf.sys BSOD from earlier rears its head.  I had a coworker upgrade the BIOS today and then got stuck in a BSOD loop.  Fixing it required going to safe mode, disabling the NVIDIA Platform Controllers & Framework device, and then installing an older NVIDIA driver.  Too late to check now but I suspect turbo boost 3.0 was enabled which is what was "saving" him from the BSOD before the BIOS update was applied.

 

If you have Intel Turbo Boost Technology 3.0 enabled, I would suggest that you try disabling it before applying the BIOS update and make sure that your system can boot up without a BSOD.

[Rinconmike]

I think I had this issue when I disabled the Turb boost 3.  I had to delete one of the entries for the NVIDIA Platform Controllers & Framework to stop BSOD.

[heikkuri]

All of you who got BSOD are running Windows 11?  So far no BSOD with Windows 10 or nvpcf.sys problems. But lets see what happens here in the future. Only 1000 device to be updated someday.

Probably doesn't help but as a reference, I installed the new BIOS over the weekend and have not experienced any issues. I'm running Windows 11 via the Beta Insider Preview, build 22631.1900 with the latest NVIDIA driver, 31.0.15.3598.

Only Windows 10 systems here. Experienced the BSOD on two of them (so far).

Is the BSOD on the reboot or after a while of using the machine?

Immediately at boot.

Do you happen to know if before the update they had the exclamation point in device manager next to the NVIDIA Platform Controllers & Framework?

 

When I had this issue, after I got back into windows I had two entries of the NVIDIA Platform Controllers & Framework.  One had the exclamation point.  I deleted that one and did not have the issue after.  I think that is what fixed it for me.  I have not tried the new bios yet.  I still have Turbo Boost 3 turned off on my system.  Nvidia Driver is 528.89 (I think it is one I download from the Nvidia website at the time trying to resolve this).  

 

 

[Aaron44126]

I don't know if there was a NVPCF error in Device Manager beforehand, but I can say that disabling the NVPCF device from safe mode was enough to allow the system to boot normally.

Well that's a huge bummer if they completely removed Turbo Max 3.0 (TBM3) altogether — just to "solve" the less than smooth process of turning it off in the BIOS for the GPU limited folks....

 

My CAD workloads are by far single thread throttled... I only use the RTX A5000 for it's 16GB of VRAM... If they did that'll slow my render times by 10-15%... 

Sounds like Dell though to go for the lowest common denominator. I didn't pick up the Precision Tower 3660/13900K as they just throttled the heck out of it to avoid customer complaints about noise/heat.
