@W1zzard Seeing an unknown component "NvAbHub" with this new version and latest 451.67 drivers (DCH/notebook on GTX 1650/Win10 x64 2004).

AssimilatorSeeing an unknown component "NvAbHub" with this new version

It's not new, and it's not unknown, there's a help text, I just have no clue what it does

Heh - so NVCleanInstall has to differentiate between known knowns, known unknowns, and unknown unknowns.

I didn't know if that help text was specific to that component, or if it was a generic "hey we've never seen this component before, display a default message". Maybe a better message would be "We know about this component, but not what it does - if you do, please contact us!"

AssimilatorWe know about this component, but not what it does - if you do, please contact us!

Great idea, any ideas to reword it a little bit more professional?

Whilst this component is recognised, its function remains unclear - any clarification would be greatly appreciated.

Judging from NvAbHub.nvi it is part of GFE: <bool name="IsGFExperienceComponent" value="true"/>

StefanMJudging from NvAbHub.nvi it is part of GFE: <bool name="IsGFExperienceComponent" value="true"/>

Correct, that's why it's listed in the GFE section and not in "unknown" (which appears when unknown component detected)

Can confirm the new notebook vs desktop feature works...

My laptop:


Versus my desktop:


May I ask what technique you used to differentiate between laptops and desktops @W1zzard ?

Also would the "add hardware support" feature allow installing new drivers with Fermi cards and older?

Check if it has a battery and no UPS, or has a lid switch

@Arctucas: Did you see a black console window? It should run for several minutes. Are you on Windows 10?

Will it help me to finally stop add my GeForce GT 650M (dGPU) in last driver to be able to use it with my eGPU (GTX 1080 Ti)?

Can i also install ShadowPlay?

W1zzard@Arctucas: Did you see a black console window? It should run for several minutes. Are you on Windows 10?

According to his system specs and his screenshot, he's on Windows 7 Ultimate.

Yes, console ran for a while.

W7, does this version only run on W10?

ArctucasYes, console ran for a while.

Not sure, let me try

Give it a try

Just tested, works fine on W7.. Any chance you didn't have internet during the signing process? It needs to contact a timestamp server

W1zzardGive it a try

Well... it's not go well. I used last NVIDIA Desktop Driver package (v451.67, Game Ready).

1.) Hardware support (Template) don't have GeForce GT 650M for laptop. It's detected only my GTX 1080 Ti and i don't have problem with it, except "famous" Error 43 which i know how to fix;
2.) I got error "Signing driver package failed";


So, after that i did everything like i did before:

1.) Launch NVIDIA Driver installer and let it unpack it on drive,
2.) Copy unpacked driver files in another folder and cancel driver installation;
3.) Added my GeForce GT 650M in "Display.Driver\nv_dispi.inf" by copy two lines "%NVIDIA_DEV.0FD1% = Section054, PCI\VEN_10DE&DEV_0FD1&SUBSYS_397217AA" under "[NVIDIA_Devices.NTamd64.10.0...17098]" and "NVIDIA_DEV.0FD1 = "NVIDIA GeForce GT 650M"" at the end of the list "[Strings]";
4.) After that i started NVCleanstall and selected unpacked and modded driver;
5.) I selected additional PhysX, GeForce Experience and ShadowPlay (and services needed for them);
6.) Everything installed normally, but GTX 1080 Ti still got Error 43. Since i forgot that i disable it BIOS GT 650M it's have got same error too;
7.) Fixed error 43 for GTX 1080 Ti and enable GT 650M in BIOS. After Windows boot i see both GPUs work fine in task manager.

I got GeForce Experience, but it mostly useless for me, since it detect GT 650M as default GPU and most services have triangle with "!".

rusTORKSigning driver package failed

Do you have an internet connection?

W1zzardDo you have an internet connection?

It is possible that i may disconnect cable from laptop, since sometime windows like to install driver without my permission. Before try all this i run DDU and delete all NVIDIA drivers.

Yeah this is super annoying, spent the whole morning trying to find a way to disable that (without completely disabling windows update), no luck.

It also do another thing, since i added unsupported GPU in driver and installed it in F7 windows mode (not today!) - it's special mode without driver certification check. Windows after some time may update it anyway as unsigned and i have to reinstall it anyway. After some time i founded that driver installation may be blocked by so called Group policy restrictions. It simple don't allow install driver on device.

It's a bit tricky and dangerous for newbie, since you have to do DDU, then install new driver and set flag on GPU via GUID Class (for GPU it's "{4d36e968-e325-11ce-bfc1-08002be10318}"). But you also can't install new driver without remove block.

Tricky, but usefull.

I let it stay as it is. Mostly it's work... except maybe ShadowPlay, but it's probably because of GT 650M set default in GFE and i don't know how to fix it.

rusTORKF7 windows mode

Not needed with my method in NVCleanstall

W1zzardNot needed with my method in NVCleanstall

Yep, it was surprise. Also, if i disable GT 650M in Task manager - some of GeForce Experience services become available.

rusTORKTask manager

Device Manager?

rusTORKbecause of GT 650M set default in GFE

Can you change the PCI bus number of these cards somehow? move to another slot?

W1zzardDevice Manager?

Yeah, this is correct. My mistake.

W1zzardCan you change the PCI bus number of these cards somehow? move to another slot?

It's laptop. =) It don't have "another slot". dGPU soldered on motherboard, eGPU connected via adapter. Both directly connected to CPU. Maybe it's work this way because display connected to GT 650M so GFE set it as default. It's just strange it forgot about this problem after i disable dGPU and GFE is like" O.K., cool".

That version works for me, thanks.

@W1zzard Just a quick one - I'm using NVCleanstall on my laptop and it does correctly identify that it is indeed a mobile GPU however, on the Select Components To Install page, when I click the Recommended option, it does not select the Optimus component. Is this by design? Generally, I like to install Optimus when possible, but is it not recommended or required?

Thanks for this great program!
