punker_4_real Posted August 4 Share Posted August 4 (edited) Is there a specific reason why 3d isn't working on windows 7 SP1 it's a nVidia 1080 Max-Q on my laptop Alienware 17 R5 it only works partially for initial installation, then after a reboot nothing... it says it's "fully working" in device manager the card works under windows 11 64bit i can't really tolerate that OS Edited August 4 by punker_4_real Link to comment Share on other sites More sharing options...
ED_Sln Posted August 4 Share Posted August 4 What system updates are installed? New drivers may require Platform Update KB2670838 to work. The SHA-2 updates seem to be installed, without them there will be a Digital Signature error. Try installing different drivers, especially older than 474.11.

Give me the device ID. 5 Link to comment Share on other sites More sharing options...

Here you go PCI\VEN_10DE&DEV_1BE0&SUBSYS_08771028&REV_A1 PCI\VEN_10DE&DEV_1BE0&SUBSYS_08771028 PCI\VEN_10DE&DEV_1BE0&CC_030000 PCI\VEN_10DE&DEV_1BE0&CC_0300 Looks like possibly the Desktop version crammed into a laptop bios version 86.04.8A.00.6B Edited August 6 by punker_4_real Link to comment Share on other sites More sharing options...
ED_Sln Posted August 6 Share Posted August 6 The required updates are not installed. You need to install platform update KB2670838, SHA-2 support KB4490628 and KB4474419-v3. Link to comment Share on other sites More sharing options...
D.Draker Posted August 6 Share Posted August 6 I know for a fact that this precise driver worked flawlessly on my friend's laptop with a 1080. It's from Microsoft certified update. https://catalog.s.download.windowsupdate.com/c/msdownload/update/driver/drvs/2018/04/8f1d9923-3457-43d7-929c-1ebb96122d58_1c548e6f1128501e7e3c8fff5bca8b6419f6cbcf.cab 5 Link to comment Share on other sites More sharing options...
D.Draker Posted August 6 Share Posted August 6 Open nv_ref_pubwu.inf and replace all occurrences of 1B80 with 1BE0, click save, when a prompt shows about the unsigned driver, click yes. 5 Link to comment Share on other sites More sharing options...

He wouldn't be able to install them at all, if he had no required updates on the machine, 5 Link to comment Share on other sites More sharing options...
D.Draker Posted August 6 Share Posted August 6 Something tells me that device is locked to the OEM manufacturers drivers only. I had a similar case in the past, only the supplied drivers worked, all drivers from Nvidia site simply crashed during high load. 5 Link to comment Share on other sites More sharing options...

So don't chase newer drivers. 5 Link to comment Share on other sites More sharing options...

As far as I know, WU graphics card drivers had worse support for different technologies, e.g. OpenGL version is usually lower than the manufacturer's driver, CUDA and OpenCL may not be supported, performance in general is lower. Please make a screenshot of GPU-Z. Link to comment Share on other sites More sharing options...

And you had doubts it wouldn't? Why? PS Have I ever given a bad driver to anyone? Edited August 8 by D.Draker 5 Link to comment Share on other sites More sharing options...
