So I jumped ship from Windows to Kubuntu last night, and It’s mostly been pretty good. However my general performance of the computer has been abysmal. Like it takes upwards of 5 seconds to open anything. All of my hardware seems to be running at max speeds, so I have no idea why it would be so sluggish? It’s as if I’m running on 2gb of ram and a cpu at like 1.5ghz. My specs are:
i7-8700k at 4.7ghz max Amd Rx 6750xt 16gb ram at 3200mhz Linux is on an m.2
Any ideas? This is practically unusable for any normal operations, let alone any gaming.
Update: So it seems like my CPU is being throttled to it’s min of 800mhz because the temp is just below 100c. Not sure why it’s so high because I never got that high even in intensive gaming on Windows
So windows also gives me a reading of just under 100C but has no problem running my cpu at 2ghz or higher. So I’ll have to take a look at my radiator and see what’s up.
I installed a SATA ssd to boot windows to because I need it for university, but didn’t mess with cooling. Thanks for the help
Your cooler isn’t working, or poor contact with the CPU maybe.
With an AIO you should not be seeing more than 60-70C on most setups.
Does windows give you just under 100C when you’re just browsing the web or watching videos??
If so then your thermal set up is not working properly. You should check to make sure you’ve got thermal paste on your CPU and the cooler is mounted properly and making good contact. Also some people may accidentally leave the clear plastic sticker on the cooler where it makes contact with the CPU.
I’ve never water cooled so I can’t give advice there.
The 8700k is rated for a max temperature of 100C so it shouldn’t really be anywhere near that at idle. https://ark.intel.com/content/www/us/en/ark/products/126684/intel-core-i7-8700k-processor-12m-cache-up-to-4-70-ghz.html
For context my 7900x is at about 40C at idle and I don’t think I’ve seen it go over 75C under load.
CPUs thermal throttle as they reach their maximum rated tempuratures which would explain why everything is running slower.
Linux may have different thermal cutoffs for when to throttle compared to Windows, so that might explain it.
I’d reseat the connector for the water pump. I just installed a new PSU last week and when I turned it on, I had no RGB. I didn’t even think I went near the RGB header, but I ended up having to reseat it.
Can you try changing the power profile to “balanced” or “performance” in gnome/kde settings? Or is it stuck to “power save”?
I’m unable to change it, I think because it’s a desktop, not a laptop
Those should work on desktop as well. What’s the result of running this command:
sudo systemctl status power-profiles-daemon
