I’m playing with the idea of maybe compiling a custom kernel at some point, but it would mainly be to trim out stuff i don’t need to speed up compile time (i’m using gnu guix, and a few months ago the nonguix substitute servers were down for multiple weeks, causing me to have to compile the kernel myself everytime it got updated). I have a 5800X3D as well and it doesn’t take too long, about half an hour i think, but i still think it’s annoying if you have to do it regularly. On my laptop it takes like 1.5 hours lol. I’m not sure if it’s worth bothering with though, cause i’m also in the process of creating a guix config for my server and then setting up the server so that i can offload builds to it for my other systems (it uses a 3900x). Btw for how long have you had your 5800X3D? I think i’ve had it since 2021 or something like that, but i think the silicon is starting to degrade a little, cause this whole time i’ve also been running it with negative 30 offset, but i’ve been experiencing hard reboots these past months with errors in the logs indicating cpu-related errors. I’ve put the offset back on auto and it seems to be working fine so far, so i think it just might need a little more power to be stable.

We’re opposites. I prefer the libre kernel and it’s not in the repo for the OS I’m using. Takes like 12 hours to compile on my 2012 laptop. I just let it run overnight when there’s an update. Been itching to throw guix on this and check it out.

Oh shiet… well, I pray my 5800X3D survives a little longer. I’d hate to upgrade in this economy D: … I’ve had it since it came out, I think. I did have some random reboots, but that was with one of its newer (?) relatives, an AMD Ryzen 7 5700G with Radeon Graphics. And I believe it was because it had ran out of RAM and SWAP or the like… ALSO LOOK: https://www.wanture.com/tech/amd-ryzen-7-5800x3d-am4-relaunch-q2/ I just happened to come across this now. How many years later and the re-release it?! xD Hilarious…

I compiled my own kernel for a few years when I first started using Linux in the late 90s. “So much faster by removing things I don’t need,” I claimed. I cringe at that now. I’ve been using stock kernels for years now. Any speed improvements from a custom kernel are more than offset by the time it takes to configure and compile it. Making one mistake could wipe out years of theoretical speed improvements as you recover, reconfigure, and recompile. Plus, if you have a problem with a piece of hardware down the road, how do you know the issue isn’t your custom kernel? I’d say, do it once or twice for the experience, or if there’s some specific reason you need it (bleeding edge hardware, for example). Some years back, I realized I’d rather be using my computers instead of administering them.
