Could someone tell of their experience with AMD on Linux? I've read some old comments online about how there's some issues with like GCC.

- rubbingalcohol 7y agoI'm running a Threadripper 2950X in my primary workstation, Ubuntu 19.10. I have not encountered a single CPU-related issue with compilation in the 6 months I've been using this setup. In fact I've had less trouble overall than I've had on my MacOS laptop. IMO Linux has finally reached a point where it's solid enough for general purpose desktop use.
- yummypaint 7y agoI have a ryzen 3600x with the x570 chipset and everything has worked flawlessly for the ~3 months since i got it. Im not into the mineuta of compiler optimizations so i cant speak to that, but there havent been any compilation failures.
- zlynx 7y agoThe 1700X and 1800X had some issues with GCC failures under heavy load. Linux apparently uses more CPU resources faster than Windows does, and caused excess voltage drop in some scenarios, as I recall reading about it. I think various sites online called it Performance Marginality. That was only a problem with some of the first gen Ryzen / Zen 1 chips. And I think it also involved the motherboard, because my 1700X never did it when I have my ASUS board set to boost with all-core overclock, but it did act a bit funny under normal settings. With the current Zen 2 chips everything seems fine. I did have some weird RAM corruption errors with my 3900X when I had the RAM set to 3600 and I did 24 thread Rust compiles. However, that didn't happen with the release version BIOS, it was only after the ABA (I think? The one that fixed RDRAND) Agesa update that was supposed to fix the excess voltage levels and I think they went too far. Everything was perfect running the RAM at default 2400 speed.
