Precision 7530 & Precision 7730 owner's thread

I let Windows choose the driver.

You could load the c:\windows\memory.dmp into a debugger like WinDbg and see which driver is on the call stack of the faulting thread. Thats how I identified the Samsung NVMe driver after my BSODs.

 

Some more bugs.

With Windows 1803, I was able to enroll my university's matriculation card onto the Dell ControlVault Contactless Smartcard app (and log in to Windows using it), but with 1809, I can't do that, and receive this error message:

I cannot for the life of me figure out where the 'policy' is that I've disabled.

 

If it happens consistently, I'll do that. Thanks.

 

For those who cannot get Intel Graphics Control Panel to work: I used DDU (Display Driver Uninstaller) from Windows Safe Mode to remove all Intel GPU stuff, unplugged network to keep Windows from auto installing from WU and reinstalled the latest DCH driver downloaded from Intel.

Now the Intel Graphics Service starts and the Control Panel works.

 

You can make the 7530/7730 dead quiet with 0 RPM fans under typical usage. My fans never turn on unless I'm running something CPU intensive.

1. Under Power Plan Advanced Settings -> PCI Express Link State Power Management -> set "Maximum Power Savings" for both battery and plugged in
2. Undervolt your CPU (and iGPU is you use it) as much as it's stable
3. On the desktop taskbar power settings slide the power mode all the way to the left "Best battery life" when plugged in and one tick from the left when on battery

Use HWiNFO64 and look at the temps under the following sections:

DELL 07NCNV (Intel PCH)
DELL EC: DELL Precision 7730

the readings under those sections drive the fan speeds as well as the CPU package temp. Mine are all generally 36-50 C unless something is using a lot of CPU.

 

Interesting I have a 7730 with the same setting you described but my PCH temperature is around 68C on ~idle when connected with dock. What you mean with 'plugged in' ? External power supply only or connection to dock ?

 

External power supply.

If I remember correctly some of us experimented and discussed earlier in this thread when the TB3 ports are connected they cause the PCH temp to go up like that. I believe using the DisplayPort or HDMI port doesn’t make the PCH temp rise as much.

 

@DerMarkus when I connect to an external display via HDMI the PCH temp is pretty much the same as I showed in screenshot above, though sometimes goes up to 50 C. Fan RPM is usually 0 and occasionally turn on and run at approx 2300 RPM (which is barely audible).

If I remember correctly from earlier in this thread, plugging in an external display via DP makes PCH go slightly up but much less than the TB3 ports which for some reason on 7530/7730 cause PCH temps to go up to 68-72 C and then fans are pretty much always on.

 

Manual fan control

I've been doing work to make manual fan control possible and as seamless as reasonable. Progress has been happening in this thread (http://forum.notebookreview.com/thr...ol-fans-on-dell-laptops-under-windows.805317/) I've been working with my Precision M6700 for the past few days, but I have just confirmed that the same solution works on the Precision 7530.

Current status:
* I've produced a command-line tool which can tell the EC to let go of fan control; this relies on a driver produced by someone else which is the subject of the very first post in that thread
* I've signed the driver but due to Microsoft's restrictions on driver signatures, you must put in a registry key to allow it to be loaded if UEFI secure boot is enabled
(You still do not have to enable test signing mode or anything like that)
* Once the EC has let go of fan control, SpeedFan can manage the fans; you can set up your own temperature thresholds for fan behavior

Also, another member is working with the author of Hwinfo64, and it looks like native support for this solution will be added there.

Downside:
With the EC not controlling the fans, the control that is available is not as granular. There are only three fan levels that can be used, 0% (0 RPM), 50% (≈2000 RPM), and 100% (≈4200 RPM). Note that the EC is able to push the fans up to around 4800 RPM which is not possible here.

I'm going to have a detailed write-up on how to set this up later this week but in the meantime I wanted to post here in case anyone wants to mess with it.

 

Really great news ! I am waiting for additional info
