Ubuntu experiences frequent freezes under heavy usage.
Ubuntu experiences frequent freezes under heavy usage.
Hello everyone, I've just started exploring Linux and really enjoyed it because of the absence of unnecessary software on Ubuntu 19.04. I've set up a dual-boot between Ubuntu 19.04 and Windows 10 using sudo update-grub, so I can pick which operating system to boot when I power on my PC. Recently, I noticed my Ubuntu system frequently freezes when trying to run high clock speeds—especially above 4.7GHz on my i5-8600K. For reference, Windows 10 runs smoothly at 4.9GHz and even higher without issues, while Ubuntu tends to lock up even at lower speeds like 4.7GHz. Could any Linux experts clarify what's happening with my machine? Some important details: I can run Windows 10 stable at 4.9GHz at 20V, but Ubuntu maxes out around 4.6GHz at 25V. I've also heard that Asus parts don't work well with Linux—my motherboard is an Asus Prime Z370-P Mk1, and I have a GTX 1060 with 418 drivers. These freezes happened on Ubuntu 19.04, Manjaro, and Lubuntu (though I'm not sure of the exact versions). My specs: i5-8600K at 4.5GHz, 1.25V for Ubuntu, 4.9GHz at 1.20V for Windows 10, running on a 16GB Corsair Vengeance DDR4-2800 RAM. I've used Asus Prime Z370-P with 418 drivers and Crucial BX500 with Ubuntu 19.04.
Linux performs exceptionally well and often highlights system instability. For a robust overclock setup, consider installing Linux and compiling Firefox from source.
It seems you're checking for system stability after a lockup. Look at the dmesg logs afterward. If they contain irrelevant information, consider excluding certain kernel modules as recommended. Test if these issues happen without your custom GPU driver and see how your computer recovers—do you need to restart? When it happens, can you change to another terminal using Ctrl+Alt+F2?
It makes sense because they employ various drivers and CPU schedulers, as well as different communication methods. There’s really nothing you can do except try adjustments like switching to a realtime kernel or using Xanmod https://xanmod.org/. Make sure you install the necessary headers if you’re using an NVIDIA GPU, otherwise you risk missing drivers.
Thanks for sharing this. I’ll remember this for future reference when I need to resolve it. It freezes and eventually forces me to shut down the PC, with no way to recover once it starts. This has never happened before, so I’ll try again next time I encounter a lockup.
