Re: Drivers installation issue with Amd radeon hd8790m.

Jump to solution

Myself no, i'm not experiencing the freezes and what not just broken drivers anywhere after 18.12.1 after installing and uninstalling every driver after dells driver from 2015 driver for the amd hd 8790m to so many drivers i can't even count them all . Have found drivers after that period just don't work with various problems from breaking the switching options, to vulkan not working to not installing itself correctly to just broken, mentioned it to amd tech got told because of the oem side of it to use the dell drivers, even went as far as uninstalling the intel 4600 dell driver and tried the intel web site only to find not even the 18.12.1 worked and ended up going back to dell drivers so my method is safe mode, ddu uninstall both intel and amd drivers goto dell sites download the intel 2019 driver install it (adds switchable options needed for amd 8790m to function) then download 2015 amd 8790m driver from dell install that restart and then use the 18.12.1 whql signed driver and just update no clean install otherwise it breaks options i have full vulkan support 1.20 (used vulkan benchmarks and doom 2016 to test it) plus normal d3d and opengl

Actually the drivers on the Dell support website are updated to 2020 version. It only shows that the driver version is of 2015 but if you go into the details page it shows updated in 2020. The 2014 version is updated to 2019 version as well. But the installation issue still remains.

I got it to work the first time, took me a whole day. But it worked and then updated via device manager to latest version and it still worked. I used the guide given here. 

You should check your charger as well because the 90 watt charger usually doesn't provide enough power and the laptop freezes frequently. The 130 watt charger provides enough power.

You can see in that picture that release date and last updated date is different, i.e 2015 and 2019.

Also for me the driver version is 15.2001 last updated December 2020.

your missing the point these drivers are old, no 2020 or 2021 drivers ie support for say vulkan=no on a 2015 driver, no support for doom eternal "minimum 20.3.1" and been to several different dell sites same drivers so post a screen shot or link where you got 2020 drivers?

a intel 4600 2020 driver is ---> 15.36.40.5162 but doesn't work correctly from intel for the e6540 and needs the dell driver and that version is latest a 2019 10.18.14.5074 and a 2015 amd dell driver for 8790m which is actually a modified 2014 driver (AMD Radeon HD 8790M - PCI\VEN_1002&DEV_6606)
