mobilenvidia 0 Report post Posted June 13 Still seems weird that 431.65 works everything newer does not All the graphics (including 880m) are pushed through the iGPU, maximus somehow switches where the input of what to display onto screen Setup stopping with error early usually means can't find GPU, something afoot You are not deleting other INFs from driver folder ? this will cause error Just replace INF Another reason is if your GPU exists in an OEM INF, then you need to remove the PCI_ID lines from the OEM INF (as I need to test the modded INFs) Install via Device manager and see what that says And yes install latest IGPU drivers as windows updates adds new features Quote Share this post Link to post Share on other sites

mobilenvidia 0 Report post Posted June 25 Any clues to what the error is ? Did you disable Driver Signature Enforcement ? (Google it) If yes go to install via Device manager and see what error is Quote Share this post Link to post Share on other sites
ieaglei 0 Report post Posted June 25 (edited) Of course I did. Despite of clean uninstalling drivers through DDU, Device manager tells that some more feasible driver is already installed Log: setupapi.dev.log another log after failure of some found driver installation through DM setupapi.dev.log Edited June 25 by ieaglei Quote Share this post Link to post Share on other sites

Try "have disk method" as described in FAQ section instead. Quote Share this post Link to post Share on other sites
ieaglei 0 Report post Posted June 25 (edited) DM successfully installs the same drivers, nonetheless 880m is not detected in games. But there is an interesting thing: some games(RE2 remake for example) detect 880m on 381 and 382 installed through Disk method Edited June 26 by ieaglei Quote Share this post Link to post Share on other sites
ieaglei 0 Report post Posted June 26 I finally found the driver (419.34 Vulkan Mobile OE 419.34 Vulkan Mobile) which detects my 880m in all tested games. Only Disk method helped to install this driver and many others successfully. So guys, thank you for everything, now Im happy. Quote Share this post Link to post Share on other sites
