Multi GPU / SLI detection not supported

[gsparx]

I've been using this for a while now to great effect, so thanks for putting it together!

Just this time I ran it, I'm now seeing this error:

PS C:\Users\garrett\Downloads> $ins_version = (Get-WmiObject Win32_PnPSignedDriver | where {$_.devicename -like "*nvidia*" -and $_.devicename -notlike "*audio*"}).DriverVersion.SubString(7).Remove(1,1)
Cannot find an overload for "Remove" and the argument count: "2".
At line:1 char:1

+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    + CategoryInfo          : NotSpecified: (:) [], MethodException
    + FullyQualifiedErrorId : MethodCountCouldNotFindBest

Any idea what might cause that? I tweaked it to on.SubString(7).Replace(".", "") but appending the .Insert(3, ".") to that results in Exception calling "Insert" with "2" argument(s): "Collection was of a fixed size."

Any help is appreciated!

Does this return anything? (Get-WmiObject Win32_PnPSignedDriver | where {$_.devicename -like "*nvidia*" -and $_.devicename -notlike "*audio*"}).DriverVersion

Do you have any drivers installed or is this a fresh windows install?

[gsparx]

Yeah, it does.

PS C:\Users\garrett\Downloads> $ins_version = (Get-WmiObject Win32_PnPSignedDriver | where {$_.devicename -like "*nvidia*" -and $_.devicename -notlike "*audio*"}).DriverVersion.SubString(7)

PS C:\Users\garrett\Downloads> $ins_version
3.8219
3.8219

PS C:\Users\garrett\Downloads> $ins_version = (Get-WmiObject Win32_PnPSignedDriver | where {$_.devicename -like "*nvidia*" -and $_.devicename -notlike "*audio*"}).DriverVersion

PS C:\Users\garrett\Downloads> $ins_version
22.21.13.8219
22.21.13.8219

It's only once I get up to the Replace part that it has issues. This is weird since I've used this before successfully several times.

[gsparx]

looks like it might be related to the fact that it's returning two results for DriverVersion

I just tweaked it to be DriverVersion[0] and it looks like that command passed

[lord-carlos]

Yes, the two results are weird. Can you show me what this returns?

(Get-WmiObject Win32_PnPSignedDriver | where {$_.devicename -like "*nvidia*" -and $_.devicename -notlike "*audio*"})

The same as before, but without the .DriverVersion.

[gsparx]

Aha you've discovered the problem.

It's because I have two GPUs installed right now. I recently added the other one. So now we're returning both GPU devices and the drivers for both.

Hello @lord-carlos , did you try maybe to use command like $ins_version = (Get-WmiObject Win32_PnPSignedDriver | Where-Object {$_.devicename -like "*nvidia*" -and $_.devicename -notlike "*audio*"} | Select-Object -First 1).DriverVersion.SubString(7).Remove(1,1).Insert(3,".") to select only one (first) graphic card and then parse driver version like before?

I understand that you use same driver for both cards and you install it for both in the same time.

[lord-carlos]

That commend works for me with single GPU. @gsparx can you try the command from @Harall on your sli setup?

(Get-WmiObject Win32_PnPSignedDriver | Where-Object {$_.devicename -like "*nvidia*" -and $_.devicename -notlike "*audio*"} | Select-Object -First 1).DriverVersion.SubString(7).Remove(1,1).Insert(3,".")
