CPU frequencies wrong

in flag

So after I installed Ubuntu to my laptop, I was amazed at how quiet the laptop became. Previously on Windows the fans constantly ran at full speed. However, when I started gaming on it, framerates became a huge problem. They're nothing like the framerates achieved on Windows. Same with High Performance mode, quiet fans, crappy framerates. So I ran lscpu, and it returned with this:

1100 MHz max frequency? 400 MHz minimum frequency? For reference 1100MHz should be minimum frequency and maximum frequency should be 4.7 GHz. Is there a way to correct this?

Probably a newer kernel version is needed for such new CPU.

kernel is already at 5.11.0-22-generic though

Looks to me as though turbo is disabled. If you are using the default intel_pstate CPU frequency driver then do `cat /sys/devices/system/cpu/intel_pstate/no_turbo` where "0" indicated enabled and "1" indicates disabled. And no, 1.1GHz is not the min frequency, it is the base frequency or max if turbo is disabled.

ok it's been a long time, i forgot about this, but yea Doug's method worked

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
