  • Thanks a lot. I will look into this.

    Reason why I use chmod is because I cant for the life of me figure out why I can’t just use sudo. Even when I set environment variable for the upp.py it refuses to run it. Even when I directly want to run it via sudo it refuses, I can only run it without sudo for whatever reason… but to overwrite pp_table I need sudo privileges and I’ve been only able to get around with chmod.

    Also I’ve tried to make a script that I will just run and will execute the commands… but I get immediately hard lock and black screen and I need to do hard reset. Same when I try to copy and overwrite the pp_table with sudo priviledges with a pre-modified pp_table.

    So I’m kinda hesitant to now run the commands on runtime, it’s possible it will hardlock during boot. I will give it more though tommorrow.

    edit:

    I just found out how to write the pp_table into VBIOS so I will try flashing modified VBIOS on the card and hope it will work. I’ll leave that for tomorrow though.







  • No it did not get warm at all because it was barely doing anything. But so that I’m fair I’ve borrowed different USB 3.2 Gen1 drive and tested also with my Fedora Laptop.

    single 4.4GB video file

    • Zen1 based Windows PC - 2min 10s (could unmount right after progress finished)
    • Zen4 based Fedora41 laptop - 3min 1s (progress finished within 1min but then took 2min to unmount)
    • Zen3 based Fedora41 PC - 5min 16s (progress finished within 20s but took almost 5min to unmount)

  • As I’ve already mentioned, sync does absolutely nothing. The copy took so long that the sync command exited 4 times while the files were still transfering and were nowhere near finishing. Regarding the watch -d grep -e Dirty: -e Writeback: /proc/meminfo command, I did not mention it in this thread but I did try it and yes, there was some almost 900k kB of data in the “Dirty” buffer that went up and down constantly even after I’ve disabled the caching.
