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

Good luck...In 30 years plus of gaming and through many systems and configurations, I've never owned a cpu that would not support my gpu--no matter what it was.  Or heard of it happening to someone else.  My R5 1600 runs perfectly in my x370 mobo my AMD RX-480.  But then, I've been with ATi/AMD since 2002, so that may well be why...;)

Me neither. I've had multiple AMD/Nvidia/Intel CPUs/GPUs never, and i mean NEVER a compatibility issue, this is the first time.

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

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!

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

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).

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

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.

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

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.

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

I can confirm the Problem.

My Setup: Ryzen 5 2600 @ Gigabyte Aorus B450 Pro Gaming Mainboard.

Got the Asus GTX 780 with DirectCU II and it doesn't work on the first (mainly) PCIE Slot, only on the second or third one which is driven by the chipset. Sadly, the second PCIE Slot is only version 2 and runs at 4x Speed, so the GPU is significant slower compared to my old Setup (i5 2500k @ ASUS Sabertooth P67).

I hope there will be a fix soon.

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

Got the same problem. Just bought a Ryzen 2700x and installed on an Asus ROG Strix x470-F Gaming (3 pcie slots). Owning already a Gigabyte GTX 780 Windforce 3X, thought why not use it as it still kicks really well for a 2013 card.

But of course i get POST vga errors as long as the card is installed in the 1st or 2nd slot. In the 3rd slot it works fine but it's slow as hell and also it messes up my usb connectors on MB and also the front audio headers as the video card is kind of big and forces things being all the way down there.

Now, for sure Gigabyte has no interest to update the bios of a 2013 video card so all hopes are in AMD maybe doing some sort of miracle on the next bios update (btw just updated today the bios with the latest version hoping that something got fixed since yesterday night when i started building up this system, but nothing changed).

I spent quite a bit on these components (cpu, mb, ram and ssd) so for sure i cannot afford spending more on a new video card. (Thinking also to contact the MB manufacturer Asus but i have a feeling they'll send me either to AMD or Gigabyte).

Hoping for the best!

Regards,

Viorel
