  • What troubleshooting steps did you take so far? I would try these:

    • different OS, maybe a live usb running fedora or ubuntu if it is possible to emulate the workload where this appears
    • bios reset to defaults, no OC not even XMP
    • memtest, either the memtest86+ boot iso or the runtime memtester can detect obvious errors
    • long smart self test on OS drive and an fsck or scrub based on FS

    Also the logs show a very old nvidia gpu which is not supported by the new driver. I don’t know if this can cause crashes, haven’t used one in ages, maybe someone else has more insight.










  • Navigate to a problematic movie or episode -> 3 dots -> Get info -> right column -> Color space

    Usually SDR is bt709 and HDR is bt2020. In older codecs (h264) 10 or 12 bit color depth can also cause issues.

    I’m not sure how tone mapping works on plex since I don’t have a pass but with Jellyfin you need to setup OpenCL which is run on the GPU so your guess that a hardware change can break it is plausible.








  • The FS feature is great, it’s just cumbersome to use without a tool.

    Snapper works well for a local backup like history both against botched updates and accidental deletion, but eats up the free space with the default settings.

    Timeshift is an easy to use GUI but doesn’t support non-default partitions.

    Also the quota support had a nasty side effect: freezing the whole system on snapshot deletion.


  • It’s hard to live up to expectations after Frieren but here are some that were memorable for me:

    • Fate Zero - it’s a battle royal with magic, the story isn’t the focus but the characters and fights are great
    • Spice and Wolf - this is about a merchant’s journey with an unusual companion (there is a new (re)adaptation coming next season, but the old version is also quite good)
    • A Certain Scientific Railgun - a sci-fi city and it’s secrets, I think it does well in the would building

  • I think calling it a “cache” is not precise. The primary function of the DRAM is to hold the dictionary for translating logical addresses (e.g. sectors) from the OS to the physical addresses (which NAND chip, which bank etc.). This indirection is needed for the controller to do wear leveling without corrupting the filesystem.

    On a SATA SSD without DRAM each read IO could mean 2 actual reads: first the dictionary to find the data and than the actual data being read. As you said HBM helps by eliminating this extra read.

    The read and write caching is just a use of the remaining DRAM capacity. Since modern Operating Systems use the general RAM for the same function it is usually just a small increase to the throughput.
