Driver install

It seems that a lot of GPU problems revolve around specific versions of drivers. Though NVidia has their own support structure, you can often learn from information reported by others who fold.

Driver install

Post by Ricorocks » Mon Jan 09, 2017 4:24 pm

Trying to do a Hot fix driver clean install. One win10 machine, will open DDU with a white window & only thing visible, upper left corner is 'DDU Launch Options.' Nothing happens at this point no matter how long I wait.

For the clean install of 376.48 would 'Revo Uninstaller' be acceptable?

Or 'programs & features' delete all NIVDIA. Anything else to be manually removed?

Or other means for prep, for the new driver

Also, since old driver has been removed, leave UN TICKED clean install of 376.48, or does this get TICKED?
_____

Note DDU worked fine on a win7 dedicated folder, I was surprised after choosing 'highly recommended' the machine did not go to safe mode

Thanks
Rico

I just installed the new driver over the old without any uninstaller and it worked.

Hi Foldy

Update with 'Aileen' & her 1050 ti on line. I'm doing 1.2 mill - 800k ppd. & roughly 70 - 45 wu's per day. With the older drivers, I would get anywhere from 1 - 4 days without a stalled GPU, (fails to re-start folding). Most probable reason for variance in ppd.

On this Win10 machine, which does not like, DDU, I did the 'FULL' driver install so now I have @prog & features:

1. NVidia graphics driver

2. GeForce experience

3. Nividia PhysX software

Can #2 & 3 be deleted

Yes #2 & #3 are not needed for folding :-)

After downloading the driver from NVidia, simply execute it. It contains its own installer and you get to choose which components to install (I use " NVidia graphics driver" only.)

Agree get it from NVIDIA!

Choosing just 'graphics driver' all others unticked, found PhysX at program & features.

One machine I used NVIDIA control panel to disable it by: at nvidia control panel choosing 'PhysX' then choosing CPU > apply

The other machine NVIDIA control panel would not open, so I deleted PhysX, using prog & features.

Thanks Guys
I'm still in my 'rookie' year of folding, Thanks for the patience

I believe Nvidia drivers place an uninstall program in Win Programs but AMD does not. To downgrade Nvidia drivers it worked when I first let the Nvidia uninstall program remove its drivers, then reboot, and needed or not I ran DDU in Safe Mode before installing new driver. If I just used DDU I had problems downgrading Nvidia driver.

Aurum, when installing Nvidia drivers, the user can select "Clean install," which completely removes the previous drivers before installing the upgrade (or downgrade) drivers.

Does anyone know if having Physx installed affects Folding performance negatively? Sure, not needed - I know that. But is it detrimental to have installed?

FAH does not care about Physx installed or not, no influence on performance ;-)
