    rx470 driver not working properly in Windows 10 (Code 43)




      I have looked at all forums and followed loads of advice, requiring removal of the card, un-installing/re-installing, certificates etc etc, but nothing has resolved my issue.


      I bought a Sapphire Nitro+ RX470 Radeon 8GB for my son's PC - Christmas upgrade on the existing HD6870 XFX Black Edition.  The PC is built on an ASUS M5A78L-M USB3 motherboard with an AMD Phenom Processor (x6 1045T 2.70GHz), with 8GB Ram.


      I have tried literally everything to install the darn card - windows recognises it in Devices Manager, but show the Code 43 and is using the standard Microsoft Display as a result.  I had a similar issue when I built my PC with a 2200G AMD Ryzen and on this the Card in built in! (Can't quite work out how I fixed it either.)


      I have tried installing from the disk (which was Vulcan VT and Crimson I think), tried the latest Adrenaline update and optional one.  Uninstalled them all with a driver removal tool and also manually, reinstalled.  Taken the card out and cleaned the connections.  Nothing is working.


      Why is it so difficult for Microsoft not to recognise the driver or for AMD to understand that this happens (Seen A LOT of people with problems), and create a wizard or troubleshooter???


      Anyway - can anyone help please?  This is seriously affecting my son's PC Fortnite game stats....


      Many thanks

          Assuming your using win10x64


          install these 18.5.1: Radeon™ RX 470 Previous Drivers | AMD

          But first, use DDU in safe mode. Use Clean and Restart option

          You might want to disconnect from the internet too. That would prevent windows from installing it's default driver.


          In DDU's options the very last option will do the same.

              Hi Hardwood,


              Thanks for taking the time to respond.  Yes, I am using win 10x64.


              Unfortunately it didn't work.  Here is what I did for anyone else that may have this issue though (or in case I missed something):


              1. Went into safe mode (Shift+Restart from start menu)

              2. Troubleshoot>Advanced Options>Start-up settings>Restart

              3. F4 for Safe mode

              4. Removed Internet cable

              5. Started DDU and selected GPU Drivers (perhaps I did something wrong here???)

              6. Selected Clean and Shutdown first time and Clean and restart second time

              7. Manually deleted "AMD" folders on C Drive (second time)

              8. Microsoft Basic Display Adapter was still showing in Devices manager (Uninstalled on second attempt)

              9. Installed 18.5.1, having previously downloaded, ran as admin, with Devices Manager open on second go.

              10. When 18.5.1 starts up, Microsoft Basic Display Adapter is re-installed (assume it scans hardware and the MBDA is part of windows and not downloaded from the internet?)

              11. Selected express install.

              12. installed without issue, said driver installed fine with tick to confirm, but there is still a Code 43 error on Devices manager and when selecting Radeon Settings no driver installed (see below).

              13. Shutdown and restarted, but no change.


              I have tried this twice now :-(


              Any other suggestions would be much appreciated, this is becoming very frustrating now!

              It is definitely a Radeon RX470 8Gb Sapphire Nitro+  !!!!
