Clokwork it starts with eye pain and if I continue i get brain fog and sometimes i can not speak properly. If i don't use PC/TV for a week it returns to normal . Strange

    machala Yes, I meant that.

    With the 1700X I was stuck with W10 1809, then I tried to upgrade to 2004 and it was a disaster.

    So I went back to 1809 and a year later I tried to upgrade to 21H1 and it was fine.

    So I'm currently using 21H1 on the 1700X+RX 480, while the 7900 seems to give me problems with 21H1, both with the RX 480, nvidia 1660 super and the integrated GPU.

    I have a feeling it is a motherboard problem but I have no certainty.

    I may try to install W10 1809 and see how it goes but I am losing hope.

    I'd like to try a 13700K but I'm afraid to spend another 1000 euros and end up with a mountain of hardware to have to sell.

    EDIT: Another option I have is to upgrade the bios to my motherboard (crosshair vi hero) so I can install a 5700X/5800X3D on it and stay that way for another couple of years.

        Lauda89 Very weird indeed, and not very encouraging. My MB is a Gigabyte with the B660 chipset and a 12400 intel CPU. I saw the same issues with MSI B660 motherboard wth an i3 12100F.

        Could it all be the chipset? Some chipsets have issues? Or specific motherboards have issues? Definitely not sure you should go for the 13xxx intel. Better approach might be to buy complete PCs and return them if you find them unsuitable. And once you test something works, you can build your own system using exactly the same HW.

        I opened a topic here half a year back asking whether people believed it could be the motherboard affecting this issue, generally people did not believe that. So I built a PC and then started to buy one graphics card after another to find the right one. And none of them was OK. It must be the motherboard I fear 🙁

        And the 1660 Super is OK in your ryzen 1700 system?

            machala "And the 1660 Super is OK in your ryzen 1700 system?"

            Unfortunately, no. This system gives me problems connected to all monitors I have (an old benq 1920*1200 CCFL that I can use with Accenture laptop and my alienware 240hz) and to all GPUs (the 7900's integrated, RX 480 and 1660 super).

            The old motherboard is a crosshair vi hero (X370 chipset) and the current one is still an asus rog B650A. The bios has the same graphics and menus but the new motherboard has horrendous output on my monitor, already from the bios! it seems to me there is something wrong! I also updated it last night to the latest version but nothing has changed.

            I will give it one last try this weekend installing W10 1809 and if it doesn't work out I will try to sell the PC to someone.

            Can you give me your exact model of motherboard? I could buy your MB and a 13700K so much they should be compatible!

                Indeed I might try to buy an already assembled PC from ZNXT and in case make the return.

                But first I want to try to change monitors to an LG 27GR95QE OLED 2K 240HZ monitor! My dream and I've never had any problems with OLED devices except for the iphone 14 pro, so I'm pretty optimistic!

                Lauda89 Why would you be getting the same motherboard as I have when I'm telling you it's already bad! It's a GIGABYTE B660 GAMING X, the large one with 3x M.2 slots.

                I am also not sure we understood each other with the graphics card… is the 1660 super bad too when you install it in your old motherboard (crosshair vi hero with ryzen 1700)?

                    machala Sorry, I understood that with the gigabyte you were able to solve the situation.

                    I only tried the 1660 in the new PC with the Ryzen 7900! I don't want to try it on the old PC.. it's the only problem-free PC I have and I don't want to risk it.

                        Lauda89 You know what? I totally understand what you mean… I am in the same situation with my old intel haswell-based system with a 660…

                        and again, no the Gigabyte motherboard is bad, very similar symptoms to what you describe with your AMD system. That's why I believe there's no guarantees you would be good with a 13xxx intel system.

                          Lauda89 Can you please tell me what type exactly is your new motherboard? Name and manufacturer… Many thanks.

                              JTL have you tried radeon 5700? seeing them for $200

                              • JTL replied to this.

                                  reaganry No, but while I'm still performing more research I have reason to believe that conventional Radeon cards may not be equivalent to the workstation variants.

                                      I try steam deck 64gb and found that steam deck very please for my eyes. Zero eye strain. Steam deck is no dithering.

                                      Lauda89 Just an update..

                                      I installed W11 with the latest updates and am using the 1660 SUPER with the DVI --> HDMI output of the monitor.

                                      With the DVI output, the situation has improved, and it gets even better by setting limited RGB. Let's say that with DVI + limited RGB I can use the PC. It's not perfect because I can't stay relaxed, but for playing with it 2/3h is ok.

                                      Unfortunately with this setting, the monitor colors suck and I am limited to 120hz (my monitor is 240hz).

                                          Received a Gigabyte 6650XT Eagle. Immediate eyestrain with both Windows 10 22H2 and Linux. Connected via Displayport. Super Resolution enabled. Patching my non-dominant right eyes results in no eyestrain. Will get an eye exam and possibly prism glasses this week. If that fails do make it better I will try the new Intel Arc GPU then W5700 then W5500.
