    It’s a MSI X470 GAMING PRO. Tried both upper x16 slots. The second one seems to be x8, but the first one doesn’t work either despite being x16. I have other m.2 slots but they’re already used up - however those are smaller SSDs so worst case I could move my OS to a SATA drive and populate those m.2 slots with the larger and newer SSDs that i bought! 😂

    as x4/x4, but PLX would divvy it all up essentially 4x M.2 at x2/x2/x2/x2, that kinda thing. If this adapter doesn’t have it and you can’t get this to work, and you’re willing to blow another hundred bucks, that other kind of adapter would def work.

    Without knowing your motherboard I’d def download the manual and ctrl+f some promising keywords such as ‘bifurcation’ or ‘PCI’ and basically hunt for anything in the manual that describes settings to enable this. Sometimes on a 3 slot board the bottom ‘chipset’ slot can be toggled to run something different than PCH, like some other controller.

    I’d also try running the adapter in every possible configuration, on the most current supported PCI-E standards and a previous generation if motherboard allows, ie: adapter top slot, GPU middle slot, GPU top slot, adapter 3rd slot (if mobo has one), disable PCI-E 4.0 or enable 3.0 each time just to see if some configuration works (kinda tedious but costs 0 dollars so

    Thanks for the hints. I’ll try to put it in gen 3.0 mode and see if I get more settings there, good idea!

    ur “main” NVME SSD. Your chipset typically has like 4 or 8 more (the very bottom slot). And you have to figure out some sort of combo where that works, and they’re not combineable. What’s worse is a lot of motherboards hard wire those extra x4 pcie lanes to the M.2 SSD slots so you get no choice.

    I’ve put the bifurcation card next to the CPU now and it only offers two x4 lanes. I thought zen2 should be able to handle bifurcation, so if it was directly hooked up with the CPU, I should get all four. Seems chipsets still have some influence over the first PCIe slot.

    Ah cool, I didn’t know that there are layers of capabilities for different requested brightnesses. Thanks for your in depth reply! I’m also a 1000 nits enjoyer but I don’t switch on any lights - I like when my eyeballs get blasted with colors. 😂

    Hey there, thanks for the comprehensive reply, I learned a lot. Also, your blog is fantastic, I’m always happy when there’s a new post =)

    Question about the last point: I feel like in SDR mode, the OLED is pushing brighter images. I almost feel like it’s underselling the capabilities at 270, but does so to give pixels a rest every now and then, in the hope that the bright spots don’t stay stationary on the screen. It’s a wild guess, I have no idea.

    I’m using all of them sometimes. ^^ Washed out colors are not an issue on AMD anymore as you said it, but on nvidia I can’t seem to fix it. I wonder if this is happening to absolutely everyone, as the arch wiki makes it sound like nvidia 545+ has been reported working…

    About the contrast: I wish I could, but I found that the factory default was 70% and it did seem to often cause noticeable dimming because the image was too bright for the max avg luminance. It felt weird and I think it’s because Alienware, like many manufacturers, just can’t resist blasting the consumer with overtuned contrasts to get a purchase out of it.






  • I’m on endeavour, though i also really liked manjaro. in terms of nvidia+wayland I’d say it’s very flaky.

    • vrr works SOMETIMES. i have to log out and in 2-3 times into my account until the option shows in the settings, and also functions as proven using vrrtest-git
    • standby corrupts cuda and you’ll need to modprobe or reboot to fix it.
    • hdr shows up but looks really grey and colorless for me, but it might be my monitor’s edid being faulty. kde’s sdr color vibrance option didn’t help.
    • external screens are dropping frames, down to 30fps, where it was fine on windows with 60.

    Keep in mind this is a 3060 laptop gpu. that means it could well be due to mux switching or whatever else. nonetheless i think nvidia seems more reliable on xorg as of this point in time, and I’m not going to buy another nvidia gpu.

    this might not apply to desktop cpus at all but i thought I’d share these in case someone else has the issues as well and knows a fix, or knows for sure it’s better on desktop, so i can reconsider my stance for a tower build 🤔

    there are too many little details to point out but windows just controls your experience too much. for example on a widescreen i don’t want to be forced to have the taskbar on the long edge. and up to including w10 the taskbar placement could be chosen. in windows 11 it’s forbidden… i installed a software to hack this but of course then explorer.exe breaks every 10 minutes.

    the spirit of computer technology is a universal tool. Microsoft strongarms the user to be a tool. so no thanks
