    My Ryzen 5 2600 doesn't work with my Asus GTX 780 DirectCU 2

    syriochan

      I bought a 2600 upgrading my 1500x, i was going to use it on a x370 killer sli and a gtx780 DirectCU2, didn't work at all. I tought it was the motherboard so i bought a x470 ultra gaming, using it with the 780, didn't work. So i borrowed a gtx 1060 from a friend and it works fine. How is that possible? A cpu that is incompatible with a specific video card? never heard before

          BTW, the gtx 780 works fine, it worked fine with my 1500x and now works with a 4790k, so not the GPU fault

              I have the same dilemma.

              I wanted to pair a GTX Titan Gen1 (6GB) (OEM Design) with an MSI X370 Pro Carbon (updated via APU to recent BIOS) and a Ryzen 5 2600. It was not working.

              So I thought, let's take an X470 Board (in my case ASRock X470 Master SLI) as it should rule out incompatibility to Pinnacle Ridge (Ryzen 2600, 2700).

              Again, it doesn't work.

               

              Facts:

              The GPU is now back on the old AM3 setup with FX CPU and working fine.

              Raven Ridge and Summit Ridge (Ryzen 1000 series and Ryzen 2200/2400g CPUs) are working fine.

              Pinnacle Ridge in combination with nVidia Generation 800 series and before does not boot (VGA undedetected as per the board beep or led)

              The reseller of the hardware pieces was doing a test run today and as a matter of fact they tried with several components (different ram, different Ryzen 1000 and 2000 series on several boards (B350, X370, X470) and the results were clear:

              All older generations of Nvidia GPUs (800 downwards), which they tried did not work, 900 series and 1000series GPUs do work though.

               

              As I don't have the money to also buy a new GPU nowadays I am considering of cancelling my purchase in its entirety, as I would not shift to intel, nor buy a new GPU.

               

              It's interesting, how this could not have been tested? There will be plenty of people with such older generations GPU, which would like to swap it over to a nice 2000 series Ryzen config.

               

              Hope it helps and that there is a fix soon!

               

              Regards

              Christian

              Description of ASRock AB350M Pro4  current BETA BIOS:

              "2.Improve NVIDIA VGA card compatibility when CSM is disabled."

               

              Maybe you try to enable CSM? I cannot test anymore....

               

              Hope it helps

                EN (translate): Hello I just purchased a Ryzen 5 2600 processor and I have the same problem with my GTX 780 gainward that does not want to work.

                I have a GTX 560ti gainward that works very well with ! so it's not compared to the old Nvidia series...

                I'm looking forward to a solution or I'd have to go back to intel...

                at least I'm glad to see I'm not an isolated case !

                ps: I installed all this on an "Asus Prime x370-pro"

                 

                 

                FR : Bonjour je viens de faire l’acquisition d'un processeur Ryzen 5 2600 et j'ai le même problème avec ma GTX 780 gainward qui ne veux pas fonctionner.
                j'ai une GTX 560ti gainward qui fonctionne très bien avec ! donc ce n'est pas par rapport au anciennes séries de Nvidia...
                J'attends avec impatience une solution sinon je serais obliger de repartir sur de l'intel ...
                en tout cas je suis content de voir que je ne suis pas un cas isolé !
                ps: j'ai installé tout ça sur une "Asus Prime x370-pro"

                  Jumping in this as well...

                   

                  I have a GTX 780 card that does not work with Ryzen 2700x. Testing other cards, before and after the 700 series work fine.

                   

                  Does anyone have a solution to this? I tried to contact AMD, but they do not answer.

                   

                  Never even heard of a capability issue with GPU and CPU either. It took me hours upon hours of troubleshooting and researching to come to this strange conclusion.

                  I'm curious why this isn't a more largely known issue. It's taken quite a bit of effort to find any information on this and every thread is either deleted by AMD or there just is no answer across the internet. I haven't found anyone that has gotten a resolution, besides getting another graphics card. However, I do not want to buy a new graphics card until the next generation, as my GTX 780 is plenty fine for now.

                   

                  Thanks in advance for any help/discussion!

                      No solution man,
                      I think that ryzen 2 is not compatible with the GK110 (GTX 780 and Titan's GPU) in particular, i think that it's a widespread problem but few people use a gk110 based gpu with a ryzen 2.

                       

                      We're too few for AMD to care, that's a reality check.
                      I changed gpu but next time i have to upgrade the CPU, i think i will not pickup another AMD processor.

                          Best way for AMD to acknowledge a problem is by Users reporting the problem via AMD Support Tickets.

                           

                          AMD EMAIL SUPPORT: Email Form . (will get an answer back from AMD Support)

                          AMD REPORT ISSUE : AMD Issue Reporting Form  (Will not get an answer back but will alert AMD Support of an issue).

                              Unfortunately, it seems AMD does not answer these support tickets or even acknowledge they are looking into the reports... It's really making me reconsider my choice to switch to AMD, to be honest.

                               

                              I think syriochan is right, though. There really is not many of us still on this old GPU with a new Ryzen 2nd Generation. On top of deleting threads and support not answering, there really does seem to be no recourse for us.

                               

                              I even reached out to Nvidia, just because I was curious to see if they have gotten any reports. The rep claims they have not gotten any reports of the 780 not working with the Ryzen 2nd generation. However, they claimed the 780 Ti certainly worked, but could not confirm on the standard 780.

                               

                              I am debating returning my Ram, CPU, and Mobo because of this and just going back to intel. But it's honestly such a hassle, even if there was just an acknowledgement of AMD looking into it/working on a fix, I'd be happy enough. I could suffer another few weeks/months to finish my system, figuring I've been using the same build for 5 years now.

                          If AMD does not care, we can try reaching out to a techtuber with this thread, if they make a video about it, maybe amd will be obliged to look into it.

                            I had the same problem.

                            Ryzen 2600

                            Asus ROG Strix B450-F (latest BIOS)

                            Gigabyte GTX 780

                             

                            The GPU is NOT recognised in either of the PCIe16 slots driven by the CPU (white LED indicating VGA problem)

                            The GPU WORKS in the 3rd PCIe16 slot which is driven by the chipset.

                            I have tried other GPU cards and they all work fine.

                            Obvious incompatibility between GTX 780 and Ryzen 2nd gen.

                            Hopefully will soon be fixed by mobo BIOS update.
