Wow.  I can't get version 15.12 to recognize that I need a display driver from any of the 15.12 links.  The 16.11.5 driver will give me the option of display driver but 15.12 won't.  I used ddu unistaller twice and have checked all connections and 15.12 just won't give me the option of downloading display driver.  I have windows 10.  Any thoughts on why this could be happening?

I have looked everywhere and when I find AMD version 15.12 it only gives me the option of downloading the audio driver when I try to download version 15.12.  When I try download the AMD driver it gives the the option to download display driver.  Does anyone know of a link where I can still get AMD 15.12 full version?

I have a 6 gpu mining rig with Windows 10, Arock pro btc 2.0 motherboard, Evga1300 g2 power supply, Radeon RX470 Armor cards, AMD version 16.11.5.  My computer keeps crashing when I loose internet connection (or crashing my internet), I don't know which one.  Windows will crash requiring re-installation of windows sometimes when it crashes.  I have already uninsatlled AMD software and used DDU to uninstall and re-installed AMD software and it still does the same thing.  Any Ideas on what could be causing this?

Got it figured out.  Thanks so much!  I installed 16.11.5 version of AMD.  After a fresh install it still had the same error so I did a process of elimination and ran one card at a time until It started messing up again.  When it tested card 5 the system started freezing.  So I tried a card I knew was good and it still did the same thing.  I then tried a new riser and it worked.  So it turned out to be the riser.  Thanks again for your help! 

Thanks.  I'll try that this evening. 

I'm running 6 AMD RX470 cards on claymore dual miner.  I downloaded the driver that came with the cards, AMD MSI version 16.7.3.  Im getting and error when I try to mine that says  "open CL error 4 cannot write buffer for DAG GPU 3 failed".  Any ideas on how to fix this?
